Explantador de Cabrera: un nuevo dispositivo para explantar endoprótesis aórticas después de reparo endovascular de aneurisma de aorta, un estudio experimental ex vivo / Cabrera explanter: a new device to explant aortic stents after endovascular aortic aneurysm repair, an ex vivo experimental study

Introducción. Las complicaciones posteriores a la reparación endovascular de aneurisma (EVAR) pueden resolverse con técnicas endovasculares. Sin embargo, cuando está indicada, la explantación de una endoprótesis es un procedimiento complejo, que se asocia a lesiones vasculares o viscerales, con alta morbimortalidad, en pacientes con edad avanzada y múltiples comorbilidades, y por lo tanto, alto riesgo quirúrgico. No existen dispositivos producidos por la industria para explantar las endoprótesis aórticas, por lo que el objetivo de este trabajo fue desarrollar un dispositivo para la explantación de endoprótesis aórticas. Métodos. Se llevó a cabo un estudio experimental, en fase preclínica, para desarrollar un dispositivo para la explantación de endoprótesis aórticas, con pruebas en modelos 3D y en un modelo animal porcino cadavérico. Resultados. Es factible desarrollar un modelo experimental de un nuevo dispositivo para explantar endoprótesis aórticas, denominado explantador de Cabrera, y comprobar su funcionamiento en un modelo animal cadavérico. El uso del explantador de Cabrera limitó el daño de la pared aórtica por parte de la endoprótesis en un 100 % al momento de su explantación en un modelo experimental ex vivo. Conclusión. Usando una jeringa septo, el explantador de Cabrera es superior a la técnica estándar de explantación de una endoprótesis al limitar la lesión de la pared aórtica, al colapsar y liberar los ganchos de fijación suprarrenal de forma controlada y segura al interior de la luz aórtica y, posteriormente, extraerla de forma rápida y efectiva, conservando la mayor cantidad de aorta sana para la posterior reconstrucción aorto-ilíaca.

Introduction. Complications after endovascular aneurysm repair (EVAR) can be resolved with endovascular techniques; however, when indicated, stent explantation is a complex procedure, which is associated with vascular or visceral injuries, with high morbidity and mortality in patients, with advanced age and multiple comorbidities, and therefore high surgical risk. There are no devices produced by the industry to explant aortic endoprostheses, so the objective of this work was to develop a device for the explantation of aortic endoprostheses. Methods. An experimental study was carried out, in the preclinical phase, to develop a device for the explantation of aortic endoprostheses, with tests in 3D models and in a cadaveric porcine animal model. Results. It is feasible to develop an experimental model of a new device for explanting aortic endoprostheses, called Cabrera explanter, and verify its operation in a cadaveric animal model. The use of the Cabrera explanter limited damage to the aortic wall by the endoprosthesis by 100% at the time of explantation in an ex vivo experimental model. Conclusions. Using a septum syringe, the Cabrera explanter is superior to the standard stent explantation technique by limiting injury to the aortic wall, collapsing and releasing the adrenal fixation hooks in a controlled and safe manner into the aortic lumen, and subsequently, extract it quickly and effectively, preserving the greatest amount of healthy aorta for the subsequent aorto-iliac reconstruction.

Embolização de múltiplos aneurismas de artéria esplênica em paciente com hiperesplenismo por hipertensão portal: relato de caso / Embolization of multiple splenic artery aneurysms in a patient with hypersplenism due to portal hypertension: a case report

Resumo Os aneurismas de artéria esplênica são o terceiro tipo mais comum de aneurismas intra-abdominais, sendo considerados o tipo mais comum de aneurismas viscerais. A hipertensão portal é um fator de risco significativo para o seu desenvolvimento. Relatamos o caso de uma paciente do sexo feminino, branca, de 52 anos, com múltiplos aneurismas de artéria esplênica com hiperesplenismo por hipertensão portal e cirrose. Por meio da angiotomografia abdominal, foram identificados seis aneurismas esplênicos. Nesse contexto, optou-se por intervenção endovascular por meio da embolização com molas de destaque controlado e material embolizante Onyx™. Os três aneurismas maiores foram tratados. As angiografias de controle mostraram boa exclusão dos aneurismas. Portanto, a técnica endovascular foi uma boa opção devido às comorbidades e às discrasias sanguíneas apresentadas. Neste caso, o procedimento foi bem-sucedido. Não houve intercorrências imediatas ou complicações a longo prazo. A paciente evoluiu bem, seguindo em acompanhamento clínico.

Abstract Aneurysms of the splenic artery are the third most common type of intra-abdominal aneurysms and the most common type of visceral aneurysms. Portal hypertension is a significant risk factor for development of these aneurysms. We report the case of a white, female, 52-year-old patient with multiple splenic artery aneurysms and hypersplenism secondary to portal hypertension and cirrhosis. Abdominal angiotomography identified six splenic aneurysms. In this scenario, an endovascular intervention was scheduled to conduct embolization using controlled release coils and Onyx™ embolization agent. The three largest aneurysms were treated. Control angiographs showed good exclusion of the aneurysms. The endovascular technique therefore proved to be a good choice considering the patient's comorbidities and blood disorders. In this case, the procedure was successful. There were no immediate or long-term complications. The patient recovered well and is in clinical follow-up.

Comparison of Prognostic Performance between Fisher and Modified Fisher Scales for Patients with Aneurysmal Subarachnoid Hemorrhage / Comparação do desempenho prognóstico entre as escalas Fisher e Fisher modificada para pacientes com hemorragia subaracnóidea aneurismática

Objective The present study aims to assess and compare the prognostic value of these two scales for predicting mortality. Method We reviewed 172 patients with aneurysmal subarachnoid hemorrhage, who were followed-up for 6 months. The Fisher and modified Fisher scales were evaluated for the prediction of mortality using logistic regressions. Results The Fisher scale was associated with mortality (odds ratio [OR]: 2; 95% confidence interval [CI]: 1.09­4.05) in the multivariate analysis. The modified Fisher scale was not associated with mortality in the multivariate analysis (OR: 1.39; 95% CI: 0.9­2.29), nor in the univariate analysis (OR: 1.24; 95%CI: 0.87­1.86). There was no significant association between Fisher score and unfavorable functional outcomes (mRS > 2) in the univariate analysis (OR: 1.33; 95%CI: 0.92­1.92), nor in the multivariate analysis (OR: 1.37; 95%CI: 0.92­2.05). There was no significant association between modified Fisher scores and unfavorable functional outcomes in the univariate analysis (OR: 1.16; 95%CI: 0.88­1.52). There was also no significant association in the multivariate analysis (OR: 1.18; 95%CI: 0.88­1.57). Conclusion Only the Fisher scale was associated with mortality. Neither of the two scales was associated with unfavorable functional outcomes (mRS > 2).

Objetivo O presente estudo tem como objetivo avaliar e comparar o valor prognós tico dessas duas escalas para predizer mortalidade. Método Revisamos 172 pacientes com hemorragia subaracnóidea aneurismática, acompanhados por 6 meses. As escalas de Fisher e modificada de Fisher foram avaliadas para a previsão de mortalidade usando regressões logísticas. Resultados A escala de Fisher foi associada à mortalidade (odds ratio [OR]: 2; intervalo de confiança [IC] 95%: 1.09­4.05) na análise multivariada. A escala Fisher modificada não foi associada à mortalidade na análise multivariada (OR: 1.39; IC95%: 0.9­2.29), nem na análise univariada (OR: 1.24; IC95%: 0.87­1.86). Não houve associação significativa entre o escore de Fisher e resultados funcionais desfavoráveis (mRS > 2) na análise univariada (OR: 1.33; IC95%: 0.92­1.92), nem na análise multivariada (OR: 1.37; IC95%: 0.92­2.05). Não houve associação significativa entre os escores modificados de Fisher e resultados funcionais desfavoráveis na análise univariada (OR: 1.16; IC95%: 0.88­1.52). Também não houve associação significativa na análise multivariada (OR: 1.18; IC95%: 0.88­1.57). Conclusão Apenas a escala de Fisher foi associada à mortalidade. Nenhuma das duas escalas foi associada a resultados funcionais desfavoráveis (mRS > 2).

Microcirugía y estrategias adyuvantes en el tratamiento de los aneurismas intracraneales

Introducción: El riesgo del ser humano de padecer un aneurisma intracraneal se calcula entre 1-2 %, en el 80 % de los casos su forma de presentación es una hemorragia subaracnoidea. Objetivo: Evaluar la utilidad de diferentes maniobras adyuvantes para facilitar la micro disección y el presillamiento del cuello de los aneurismas intracraneales. Metodología: Se realizó un estudio descriptivo con todos los pacientes admitidos en el servicio de neurocirugía del Hospital "Roberto Rodríguez", en Morón, Ciego de Ávila, Cuba, que presentaron un diagnóstico de aneurisma intracraneal y que fueran intervenidos con técnica de microcirugía para su exclusión de la circulación, en el periodo comprendido entre enero de 1997 y diciembre del 2020. Resultados: 201 pacientes fueron intervenidos, 198 (98,51 %) con aneurismas de la circulación anterior y solo 3 (1,49 %), de la circulación posterior. En total fueron abordados 252 sacos, se utilizaron estrategias adyuvantes al procedimiento convencional para facilitar el acto del presillamiento aneurismático como lo fueron el drenaje espinal continuo, la ventriculostomìa al exterior para drenaje de LCR y monitorización continua de la PIC y de la presión de retracción cerebral, cierre temporal de la arteria madre, succión retrograda descompresión en los aneurismas gigantes. El 74,62 % de los casos se recuperaron sin ningún tipo de síntomas o secuelas y la mortalidad fue del 1,49 %. Discusión: La microcirugía resulta un procedimiento eficaz, con elevado nivel de eficiencia, para el tratamiento de los aneurismas intracraneales en nuestro medio. Las estrategias adyuvantes facilitan la relajación del parénquima, la disección y el presillamiento del cuello aneurismático.

Introduction: The human risk of suffering from an intracranial aneurysm is estimated between 1-2%, in 80% of cases its presentation is a subarachnoid hemorrhage. Objectives: To evaluate the usefulness of different adjunctive maneuvers to facilitate micro dissection and clamping of the neck of intracranial aneurysms. Method: We have carried out a descriptive study including all the patients admitted in the neurosurgery department of "Roberto Rodríguez" Hospital in Moron, Ciego de Avila, Cuba with the diagnosis of intracranial aneurysms who were operated on through microsurgical cliping techniques in the period between january 1997 and december 2020. Results: 201 patients were operated on, 198 (98.51%) with aneurysms of the anterior circulation and only 3 (1.49%), of the posterior circulation. A total of 252 sacs were approached, adjuvant strategies to the conventional procedure were used to facilitate the act of aneurysmal clamping, such as continuous spinal drainage, ventriculostomy to the outside for CSF drainage and continuous monitoring of ICP and brain retraction pressure, temporary closure of the mother artery, retrograde suction decompression in giant aneurysms. 74.62% of the cases recovered without any type of symptoms or sequelae, and mortality was 1.49%. Discussion: Microsurgery is an effective procedure, with a high efficiency index, for the treatment of intracranial aneurysms in our environment. Adjunctive strategies facilitate parenchymal relaxation, dissection, and clamping of the aneurysmal neck.

Tratamiento endovascular de aneurismas con anatomía aórtica compleja / Endovascular treatment of aneurysms with complex aortic anatomy

RESUMEN Introducción: la anatomía arterial es la principal limitante para el abordaje aórtico endovascular estándar. Presentamos nuestra experiencia para la reparación endovascular de aneurismas aórticos complejos. Material y métodos: estudio observacional retrospectivo en pacientes con aneurismas complejos (yuxta/pararrenales y toracoabdominales) tratados en forma consecutiva mediante: endoprótesis fenestradas (FEVAR), ramificadas (BEVAR), con EndoAnchors (ESAR), o en chimenea (ChEVAR). La decisión de la técnica fue determinada con base en la anatomía arterial. Resultados: se evaluaron los últimos 50 procedimientos (6 mujeres; edad promedio 71,3 años; diámetro 69,6mm; 3 pacientes con aneurismas complicados), de los cuales 22 recibieron FEVAR (2,8 fenestraciones / paciente), 11 BEVAR, 11 ESAR y 6 ChEVAR (1,8 chimeneas /paciente). La tasa de éxito técnico fue del 100% (ausencia de endoleak I o III con permeabilidad adecuada de los vasos viscerales). A 30 días 3 pacientes fallecieron (6%). Durante el seguimiento, 5 pacientes presentaron oclusión de la arteria renal, repermeabilizada en 4. Cuatro pacientes desarrollaron un endoleak tipo IA (3 ESAR secundarios y un ChEVAR), un paciente un endoleak IC y un cuarto uno IIIB (22%, 3 de los 11 ESAR, ninguno de los FEVAR industriales). En el análisis de supervivencia, la supervivencia global fue del 88,6% al año, y libre de reoperación del 86,5%. Conclusiones: se trata de la primera publicación en nuestro medio que muestra un enfoque global del paciente con un aneurisma de aorta complejo, de acuerdo con sus características anatómicas. Estas tecnologías ya desempeñan un papel primario en el tratamiento de estos pacientes.

ABSTRACT Background: Arterial anatomy is the main limiting factor for standard endovascular aortic (EVAR) approach. We present our experience for endovascular repair of complex aortic aneurysms. Material and Methods: This is a retrospective observational study in patients with complex aneurysms (juxta/pararenal and thoracoabdominal) treated consecutively with: fenestrated (FEVAR), branched (BEVAR), EndoAnchors (ESAR), or chimney (ChEVAR) stents. The decision of the technique was determined based on the arterial anatomy. Results: The last 50 procedures were evaluated (6 women; mean age 71.3 years; diameter 69.6 mm; and 3 patients with complicated aneurysms), among whom 22 received FEVAR (2.8 fenestrated stents/patient), 11 BEVAR, 11 ESAR and 6 ChEVAR (1.8 chimney stents/patient). Technical success rate was 100% (absence of type I or III endoleak with adequate patency of the visceral vessels). Three patients died within the first 30 days (6%). During follow-up, 5 patients presented with renal artery occlusion, treated successfully in 4 cases. Four patients developed type IA endoleak (3 secondary ESAR and one ChEVAR), one patient IC endoleak and almost a quarter of cases type IIIB endoleak (22%, 3 out of 11 patients receiving ESAR, none of the industrial FEVAR group). In survival analysis, overall survival analysis was 88.6% at one year, and 86.5% of cases were free from reoperation. Conclusions: This is the first publication in our setting that shows a global approach to the patient with complex aortic aneurysm, according to the anatomical characteristics. These technologies already play a primary role in the treatment of these patients.

Factores predictivos de rotura de aneurismas intracraneales / Rupture Predictive Factors for Intracranial Aneurysms

Introducción: Un aneurisma intracraneal roto provoca una hemorragia subaracnoidea. La enfermedad presenta una alta mortalidad y morbilidad. Sin embargo, no todos se rompen. Mejorar la predicción de rotura permitirá un tratamiento quirúrgico preventivo en un grupo de pacientes y evitará una intervención quirúrgica con riesgos en otro grupo de enfermos. Es necesario identificar factores predictivos para mejorar la estratificación del riesgo de rotura y optimizar el tratamiento de los aneurismas intracraneales incidentales. Objetivo: Identificar factores predictivos de rotura de aneurismas intracraneales. Métodos: En una muestra de 152 pacientes espirituanos con aneurismas intracraneales saculares rotos (n = 138) y no rotos (n = 22) y 160 imágenes de angiografía por tomografía computarizada, se realizaron mensuraciones de los índices o factores morfológicos, los cuales se combinaron mediante análisis de regresión logística con variables demográficas y clínicas. Resultados: El grupo de edad con mayor frecuencia de presentación de aneurismas fue el de mayor de 65 años. La muestra estuvo representada, en su gran mayoría, por el sexo femenino. Se identificaron tres factores clínicos y cuatro factores morfológicos estadísticamente significativos, asociados con la rotura. El índice de no esfericidad (p = 0,002 y el sexo femenino (p = 0,02) fueron los de mayor significación estadística. Conclusiones: Se detectaron siete factores predictivos de rotura de aneurismas intracraneales estadísticamente significativos, de los cuales el índice de no esfericidad resultó el de mayor significación(AU)

Introduction: A ruptured intracranial aneurysm causes a subarachnoid hemorrhage. The disease has high mortality and morbidity. However, not all of them break. Improving the rupture prediction will allow preventive surgical treatment in a group of patients and it will avoid risky surgical intervention in another group of patients. It is necessary to identify predictive factors to improve rupture risk stratification and to optimize treatment of incidental intracranial aneurysms. Objective: To identify rupture predictive factors for intracranial aneurysms. Methods: Measurements of the morphological indices or factors were performed in a sample of 152 patients from Sancti Spiritus with ruptured (n = 138) and unruptured (n = 22) saccular intracranial aneurysms and 160 computed tomography angiography images. They were combined using logistic regression analysis with demographic and clinical variables. Results: The age group with the highest frequency of aneurysm presentation was older than 65. The sample was represented, in its vast majority, by the female sex. Three clinical factors and four statistically significant morphological factors associated with rupture were identified. The non-sphericity index (p = 0.002) and the female sex (p = 0.02) were the most statistically significant. Conclusions: Seven statistically significant predictors of intracranial aneurysm rupture were detected, the non-sphericity index being the most significant(AU)

Prevalência de aneurismas viscerais raros em 92.833 angiotomografias (2005-2021) / Prevalence of rare visceral aneurysms on 92,833 CAT scans (2005-2021)

Resumo Contexto Ainda são incomuns os estudos de prevalência de aneurismas viscerais raros, e os poucos estudos que focalizaram esses aneurismas observam taxas de prevalência em grupos de pacientes com aneurismas viscerais, mas pouco se conhece sobre a sua prevalência na população geral. Objetivos Avaliar a prevalência de aneurismas viscerais raros em angiotomografias realizadas para diagnóstico e seguimento de pacientes com diferentes patologias vasculares. Métodos Este estudo transversal partiu do acesso a todos os laudos de angiotomografias realizadas entre janeiro de 2005 e julho de 2021 em hospital privado de excelência situado na cidade de São Paulo. Foi utilizado um programa de mecanismo de busca de laudos pré-indexados, cuja base de dados é o Sistema de Informação Radiológica (RIS), para acesso aos laudos de pacientes com aneurismas intra-abdominais. Resultados Foram acessados laudos de angiotomografias de 92.883 pacientes, dos quais 2.597 (2,795%) apresentavam aneurismas intra-abdominais, sendo 937 (1,063%) viscerais, incluindo 158 (0,171%) aneurismas viscerais raros, mais frequente entre homens e nos seguintes segmentos: tronco celíaco (0,098%), artéria mesentérica superior (0,033%), artéria gástrica esquerda (0,010%), artéria pancreático-duodenal (0,009%), artéria gastroduodenal (0,005%) e arco pancreático (0,004%). Prevalências menores foram encontradas em outros diferentes segmentos. Achados adicionais revelaram taxa de concomitância de aneurismas viscerais raros com outros aneurismas intra-abdominais entre 11,11% e 66,67%. Conclusões A prevalência de aneurismas viscerais raros em ampla população submetida a angiotomografias foi de 0,171%, com maior comprometimento nos pacientes do sexo masculino.

Abstract Background Studies on the prevalence of rare visceral aneurysms are still scarce and the few studies that have focused on these aneurysms present prevalence rates in groups of patients with visceral aneurysms, but little is known about their prevalence in the general population. Objectives To assess the prevalence of rare visceral aneurysms on CAT scans performed for diagnosis and follow-up of patients with other vascular pathologies. Methods This cross-sectional study began by accessing all reports from CAT scans performed between January 2005 and July 2021 at a private hospital of excellence located in the city of São Paulo. A software program for pre-indexed reports was used to search the Radiological Information System (RIS) database to identify reports of patients with intra-abdominal aneurysms. Results CAT scan reports from 92,883 patients were accessed. Of these, 2,597 (2.795%) showed intra-abdominal aneurysms, 937 (1.063%) of which were visceral, including 158 (0.171%) rare visceral aneurysms, which were more frequent among male patients and in the following segments: celiac trunk (0.098%), superior mesenteric (0.033%), left gastric (0.010%), pancreatic-duodenal (0.009%), and gastroduodenal arteries (0.005%) and the pancreatic arch (0.004%). Lower prevalence was found in other segments. Additional findings revealed concomitance of rare visceral aneurysms with other intra-abdominal aneurysms ranging from 11.11% to 66.67%. Conclusions The prevalence of rare visceral aneurysms in a large population undergoing CAT scan was 0.171%, with greater involvement in male patients.

Giant splenic artery aneurysm: case report / Aneurisma gigante da artéria esplênica: relato de caso

Abstract True splenic artery aneurysms are exceedingly rare and the medical literature contains only a limited number of reports on this pathology. Presently, there remains a lack of consensus regarding the optimal management and treatment approaches for patients in this category. Over the course of the last century, significant changes have occurred in the realm of surgical options, transitioning from open and endovascular procedures to the more advanced laparoscopic and robotic interventions. The propensity for these aneurysms to rupture underscores the need for timely intervention. The risk of rupture is notably elevated in patients harboring giant splenic artery aneurysms. In this report, we present the case of a 55-year-old woman diagnosed with a giant splenic artery aneurysm measuring 12x12 cm in diameter. She presented with notable weakness, discomfort, and pain in the left subcostal area. In response to her complaints and after thorough evaluation, we opted for a surgical procedure encompassing distal pancreatic resection in conjunction with splenectomy and resection of the giant splenic artery aneurysm.

Resumo Os aneurismas verdadeiros da artéria esplênica são extremamente raros, e há um número limitado de relatos sobre essa condição na literatura médica. Atualmente, não há consenso sobre as abordagens ideais de manejo e tratamento para pacientes que se enquadram nessa categoria. Ao longo do século passado, ocorreram mudanças significativas no domínio das opções cirúrgicas, passando de procedimentos abertos e endovasculares para intervenções laparoscópicas e robóticas mais avançadas. A propensão à ruptura do aneurisma ressalta a necessidade de intervenção em tempo oportuno. O risco de ruptura é notavelmente elevado em pacientes com aneurismas gigantes da artéria esplênica. Neste relato, apresentamos o caso de uma mulher de 55 anos diagnosticada com aneurisma gigante de artéria esplênica medindo 12x12 cm de diâmetro. A paciente apresentava fraqueza notável, desconforto e dor na região subcostal esquerda. Em resposta às suas queixas e após avaliação minuciosa, optamos por um procedimento cirúrgico que incluiu pancreatectomia distal associada a esplenectomia e ressecção do aneurisma gigante da artéria esplênica.

Aneurismas de las arterias pulmonares en relación al síndrome de Hughes Stovin / Aenurysms of the pulmonary arteries in relation to Hughes Stovin syndrome

El síndrome de Hughes Stovin es una vasculitis de pequeños y grandes vasos, más frecuente en hombres jóvenes. Se manifiesta con trombosis y aneurismas. Inicia con tromboflebitis que evoluciona a aneurismas con eventual desenlace fatal por ruptura de los mismos. Algunos autores consideran el síndrome de Hughes Stovin como una variante de la enfermedad de Behçet. El diagnóstico es clínico y el tratamiento de primera línea son los corticoides y la ciclofosfamida. Frente a un caso de trombosis, la anticoagulación es controversial por el riesgo de sangrado. Presentamos el caso de un varón joven con cuadro clínico compatible en el cual se descartaron otras patologías con requerimiento de tratamiento quirúrgico por mala evolución clínica.

Hughes Stovin syndrome is characterized by small and big vessels vasculitis, more commonly presented in young men. Initially it manifests with thrombophlebitis and aneurysms which can cause fatal bleed due to rupture. Some authors consider Hughes Stovin syndrome as a variant of Behcet's disease. Diagnosis is made by clinical findings and the first line treatment are corticosteroids and cyclophosphamide. Anticoagulation is controversial due to the increased risk of hemorrhage.

Aneurismas ventriculares en una población de pacientes con cardiomiopatía chagásica / Ventricular aneurysms in a chronic Chagasic cardiomyopathy population

Resumen Antecedentes: Los pacientes con enfermedad de Chagas pueden desarrollar cardiomiopatía crónica (CChC); los aneurismas ventriculares son característicos de esta condición. Objetivo: Analizar una población de pacientes con CChC con aneurismas ventriculares, buscando asociaciones entre las variables sexo, edad, síntomas, fracción de eyección del ventrículo izquierdo (FEVI), tamaño de los aneurismas y presencia de arritmias ventriculares. Método: Los pacientes fueron valorados con historia clínica, electrocardiografía (ECG), radiología, ecocardiografía y Holter. Resultados: De 627 pacientes con CChC, 60 (9.6%) presentaron aneurismas (60%). Había una relación significativa entre edad mayor de 50 años y FEVI normal. El valor predictivo negativo de clase funcional I y ECG sin anomalías del QRS para detectar FEVI < 50% o taquicardia ventricular fue del 47.4%. No hubo relación significativa entre anomalías del QRS con FEVI < 50% ni taquicardia ventricular. Los aneurismas grandes estaban asociados a FEVI < 50%, pero no fueron predictores de taquicardia ventricular. No hubo asociación significativa entre volúmenes de fin de diástole del ventrículo izquierdo y FEVI o taquicardia ventricular; los pacientes en fase B1-2 no presentaron mayor riesgo de taquicardia ventricular que los de fase C-D. Conclusiones: En los pacientes con CChC se recomienda un estudio integral con ecocardiografía y Holter; el valor predictivo negativo de la clínica y del electrocardiograma es muy reducido.

Abstract Background: Chagas disease patients can develop chronic cardiomyopathy; ventricular aneurysms are characteristic of this condition. Objective: A population of patients with Chagas cardiomyopathy with ventricular aneurysms was analyzed, looking for associations between variables sex, age, symptoms, left ventricular ejection fraction, size of aneurysms and presence of ventricular arrhythmias. Method: The patients were evaluated with a clinical history, electrocardiography, radiology, echocardiography and Holter. Results: Of 627 patients with CChC, 60 (9.6%) had aneurysms, 60%. There was a significant relationship between age older than 50 years and normal LVEF. The negative predictive value of Functional Class I and ECG without QRS abnormalities to detect LVEF < 50% or ventricular tachycardia was 47.4%. There was no significant relationship between QRS abnormalities with LVEF < 50% or ventricular tachycardia. Large aneurysms were associated with LVEF < 50% but were not predictive of ventricular tachycardia. There was no significant association between left ventricular end-diastole volumes and LVEF or ventricular tachycardia; patients in phase B1-2 did not present a greater risk of ventricular tachycardia than those in phase C-D. Conclusions: In patients with CHCC, a comprehensive study with ECO and Holter is recommended, the negative predictive value of the symptoms and the electrocardiogram is very low.

Enfermedad de Kawasaki en pediatría: caso clínico / Kawasaki disease in pediatrics: a case report

la enfermedad de Kawasaki (EK) es una vasculitis multisistémica que se presenta en la infancia. Por lo general es una afección aguda, febril, autolimitada, de etiología desconocida y puede desarrollar alteraciones cardiovasculares; su expresión clínica es variable: presenta inflamación de los vasos de mediano calibre y de múltiples tejidos: pulmonar, meníngeo, cardiaco, urinario, gastrointestinal, musculoesquelético, neurológico o linfático. El diagnóstico y el tratamiento buscan disminuir la duración de los síntomas y prevenir la presencia de aneurismas coronarios.

Kawasaki disease (KD) is a multisystemic vasculitis that presents in childhood. It is usually an acute, febrile, self-limited disease of unknown etiology and may develop cardiovascular alterations; its clinical expression is variable as it presents inflammation of medium caliber vessels and multiple tissues: pulmonary, meningeal, cardiac, urinary, gastrointestinal, musculoskeletal, neurological or lymphatic. Diagnosis is clinical, and treatment aims to reduce the duration of clinical symptoms and prevent the presence of coronary aneurysms. Objective: to describe the clinical case of an infant patient with KD, in which clinical criteria characteristic of this pathology were identified. Case report: a 22-month-old male patient was admitted to the emergency room with a 14-day evolutionary clinical picture consisting of fever, emetic episodes, abdominal pain, unresponsive to acetaminophen, and diarrheal episodes. Two days later, he manifested generalized exanthema in the inguinal region that spread to the right testicle, back, and thorax. Subseguently, he presented bilateral nonpurulent conjunctivitis for three days. He received treatment with topical steroids and oral antihistamines; partial improvement with subseguent evolution in right testicularedema and bilateral desquamation in hands and feet. KD was suspected, a transthoracic echocardiogram was sent without coronary aneurysmal dilatations, and treatment with ASA was started without indication, given the evolution of immunoglobulin. Conclusions: KD is infrequent in childhood and should be suspected in patients with prolonged febrile symptoms unresponsive to conventional treatments and in whom the presence of other pathologies is ruled out.

a doença de Kawasaki (DK) é uma vasculite multissistêmica que ocorre na infância. Geralmente é uma doença aguda, febril, autolimitada, de etiologia desconhecida, podendo desenvolver alterações cardiovasculares; sua expressão clínica é variável, apresentando inflamação de vasos de médio porte e de múltiplos tecidos: pulmonar, meníngeo, cardíaco, urinário, gastrointestinal, musculoesquelético, neurológico ou linfático. O diagnóstico é clínico e o tratamento visa reduzir a duração dos sintomas clínicos e prevenir a presença de aneurismas coronábanos. Objetivo: descrever o caso clínico de um paciente infantil com DK, no qual foram identificados critérios clínicos característicos dessa patologia. Caso clínico: paciente do sexo masculino, 22 meses de idade meses de idade, admitido no departamento de emergência com um curso clínico de 14 dias, consistindo em febre, episódios eméticos e dor abdominal, sem resposta ao acetaminofeno, além de episódios diarreicos. Dois dias depois, ele desenvolveu uma erupção cutánea generalizada na região inguinal que se espalhou para o testículo direito, costas e tórax. Posteriormente, ele apresentou conjuntivite bilateral não purulenta por três dias. Ele foi tratado com esferoides tópicos e anti-histamínicos orais; houve melhora parcial com posterior evolução do edema testicular direito, descamação bilateral nas mãos e nos pés. Suspeitou-se de DK, portanto foi realizado ecocardiograma transtorácico sem dilatações aneurismáticas coronarianas e iniciado tratamento com AAS, sem indicação devido ao tempo de evolução da imunoglobulina. Conclusões: a DK não é frequente na infância e deve ser suspeitada em pacientes com sintomas febris prolongados que não respondem aos tratamentos convencionais e nos quais a presença de outras patologias é descartada.

Tratamento endovascular na doença de Behçet: uma revisão integrativa / Endovascular treatment in Behçet's disease: an integrative review

Resumo A doença de Behçet (DB) é caracterizada por ser uma doença rara, crônica, recidivante, inflamatória e multissistêmica. Quanto ao diagnóstico, não existe nenhum teste universalmente descrito; logo, ele é feito de maneira clínica, por meio da presença da sua tríade clássica de sinais: úlceras orais, úlceras genitais e uveíte (inflamação do trato uveal do olho). O objetivo deste estudo foi avaliar a importância do tratamento endovascular na doença de Behçet, sendo que a revisão de literatura para obter essa resposta foi realizada a partir de 30 artigos publicados entre 2002 e 2021. A DB acomete tanto o sistema venoso quanto o arterial. A ruptura de aneurismas é a principal causa de morte e necessita de tratamento, podendo ser clínico, cirúrgico aberto ou por via endovascular. A cirurgia endovascular vem ganhando espaço no tratamento cirúrgico nos casos de aneurismas arteriais, inclusive nos relacionados com DB, apesar de a terapia de escolha ainda ser controversa.

Abstract Behçet's Disease (BD) is a rare, chronic, relapsing, inflammatory, and multisystemic disease. There is no universally described test for confirming diagnosis, so it is made clinically, on the basis of its classic triad of signs: oral ulcers, genital ulcers, and uveitis (inflammation of the uveal tract of the eye). The aim of this study is to evaluate the importance of endovascular treatment in Behçet's disease. The literature review conducted to achieve this objective covered 30 articles published between 2002 and 2021. Behçet's Disease affects both the venous and arterial systems. Rupture of aneurysms is the main cause of death and thus requires treatment, which can be clinical, open surgical, or endovascular. Endovascular surgery has been gaining ground for surgical treatment of arterial aneurysms, including those related to BD, although the therapy of choice is still controversial.

Influencia del error diagnóstico en el pronóstico de la hemorragia subaracnoidea aneurismática en uruguay: analisis de una serie de 149 pacientes en un período de tiempo prepandemia y durante la pandemia SARS-Cov2 / Influence of diagnostic error on the prognosis of aneurysmal subarachnoid hemorrhage in Uruguay: analysis of a series of 149 patients in a pre-pandemic period and during the SARS-Cov2 pandemic

Introducción:La hemorragia subaracnoidea espontánea (HSA) presenta aproximadamente el 5% de todos los ACV, siendo una patología de alto impacto en la sociedad por su elevada morbi-mortalidad. La clínica de presentación es variada, lo cual lleva múltiples veces a dificultades en el diagnóstico. El objetivo de este trabajo es analizar el error diagnóstico que existe en esta patología y evaluar si el mismo se vio modificado por la interposición de la Emergencia Sanitaria declarada en el país por la pandemia del SARS-Cov2. Materiales y Métodos: es un estudio prospectivo y multicéntrico, incluyendo a todos los pacientes que presentaron HSA en el Uruguay entre el 1 de noviembre del 2019 y el 31 de julio de 2020. Se analizaron acuerdo con 3 períodos: 1) pre-pandemia, 2) cuarentena general, y 3) nueva normalidad. Se incluyeron todos los pacientes mayores de 18 años que consultaron y se les diagnosticó una HSA espontánea aneurismática. Se definió́ error diagnóstico a la imposibilidad de reconocer esta patología en la consulta médica inicial otorgándole el alta. El análisis se procesó utilizando el software SPSS versión 22. La investigación fue aprobada por todos los Comité de Ética de los diferentes centros que participaron del estudio. Resultados: de un total de 149 pacientes, la edad media fue de 57,23 años, con mayor frecuencia en el sexo femenino. Se constató error diagnóstico en 38 pacientes (25,5%), con mayor porcentaje durante la cuarentena general. El retraso en el diagnóstico por problemas asistenciales fue de un 2,6%. Se evidenció un 22,8% de complicaciones por el tratamiento indicado, y un 71,1% por la HSA, con una mortalidad global del 51,7%. Conclusiones: en el presente trabajo se observó un error diagnóstico elevado, evidenciando una relación directa y significativa con la cefalea y la HSA leve (HyH 1 y 2) como formas de presentación. Hubo un porcentaje mayor de HSA graves en comparación a la literatura, con una relación directa y significativa entre la presencia de vasoespasmo y la mortalidad con el error diagnóstico. También es claro que la crisis sanitaria determinó que ese error diagnóstico aumentara durante los primeros meses de la pandemia en Uruguay.

Introduction: Spontaneous subarachnoid hemorrhage (SAH) represents approximately 5% of all strokes, being a pathology of high impact in society, due to its high morbidity and mortality. The clinical presentation is varied, which leads many times to difficulties in diagnosis. The objective of this work is to analyze the diagnostic error that exists in this pathology, and to assess whether it was modified by the introduction of the Health Emergency declared in the country by the SARS-Cov2 pandemic. Materials and Methods: it is a prospective and multicenter study, including all patients who presented SAH in Uruguay between November 1, 2019 and July 31, 2020. They were analyzed according to 3 periods: 1) pre-pandemic, 2) general quarantine, and 3) new normality. All patients over 18 years of age who consulted and were diagnosed with spontaneous aneurysmal SAH were included. Diagnostic error was defined as the inability to recognize this pathology in the initial medical consultation and discharge. The analysis was processed using SPSS version 22 software. The research was approved by all the Ethics Committees of the different centers that participated in the study. Results: of a total of 149 patients, the mean age was 57.23 years, more frequently in the female sex. Diagnostic error was found in 38 patients (25.5%), with a higher percentage during general quarantine. The delay in diagnosis due to healthcare problems was 2.6%. There were 22.8% complications due to the indicated treatment, and 71.1% due to SAH, with an overall mortality of 51.7%. Conclusions: in the present work, a high diagnostic error was observed, showing a significant direct relationship with headache and mild SAH (HyH 1 and 2) as forms of presentation. There was a higher percentage of severe SAH compared to the literature, with a direct and significant relationship between the presence of vasospasm and mortality with diagnostic error. It is also clear that the health crisis determined that this diagnostic error increased during the first months of the pandemic in Uruguay

Aneurismas por Estreptococo Pneumoniae / Aneurysms by Streptococcal Pneumoniae

El Estreptococo Pneumoniae es un microorganismo patógeno capaz de causar en humanos diversas infecciones y procesos invasivos severos, siempre graves y potencialmente letales. El objetivo de este trabajo fue mostrar la infrecuente presencia del Estreptococo Pneumoniae en la aparición de los aneurismas micóticos aórticos y de arterias periféricas, una asociación muy particular que coloca al cirujano vascular ante una especial conducta terapéutica encaminada a erradicar la infección, evitar la ruptura y sustituir la arteria, para mantener la continuidad de la luz del vaso y prevenir situaciones graves de isquemia(AU)

Streptococcal Pneumoniae is a pathogenic microorganism capable of causing in humans various infections and severe, always serious and potentially lethal invasive processes. The objective of this work was to show the rare presence of Streptococcal Pneumoniae in the onset of aortic mycotic aneurysms and peripheral arteries, a very particular association that places the vascular surgeon in an special therapeutic behavior aimed at eradicating the infection, preventing ruptures and replacing the artery, to maintain the continuity of vessel's light and prevent serious ischemia's situations(AU)

Aneurisma de la arteria carótida interna como lesión compresiva de la vía visual / Internal carotid artery aneurysm as a compressive lesion of the visual pathway

El diagnóstico temprano de las lesiones compresivas del nervio óptico adquiere cada vez mayor importancia. La descompresión precoz de este o del quiasma puede resultar una mejora significativa de la función visual, mientras que el diagnóstico erróneo puede ocasionar pérdida visual irreversible, disfunción neurológica o la muerte. Las causas de la compresión de la vía visual anterior son increíblemente variadas. Los meningiomas, los tumores hipofisarios y los aneurismas son las lesiones comúnmente más identificadas como causa de neuropatía óptica compresiva sin edema del disco. Presentamos una paciente femenina de 50 años de edad, quien se sometió a la cirugía de catarata congénita del ojo izquierdo, sin mejoría de la función visual, a lo que se sumó el empeoramiento inespecífico de la calidad visual. La psicofísica visual, la campimetría automatizada y la tomografía de coherencia óptica aportaron hallazgos sugestivos de compresión de la vía visual intracraneal. Se indicó imagen por resonancia magnética de cráneo y órbitas para confirmar la sospecha diagnóstica. La angiografía cerebral demostró la presencia de un aneurisma de la arteria carótida interna, que se trató por vía endovascular con resultados satisfactorios(AU)

The importance of early diagnosis of compressive lesions of the optic nerve is on the increase. Timely decompression of the optic nerve or the optic chiasm may bring about significant visual function improvement, whereas erroneous diagnosis may result in irreversible visual loss, neurological dysfunction or death. The causes of compression of the anterior visual pathway are incredibly varied. Meningiomas, pituitary tumors and aneurysms are the lesions most commonly identified as causes of compressive optic neuropathy without disc edema. A case is presented of a female 50-year-old patient undergoing congenital cataract surgery of her left eye without visual function improvement, alongside unspecific visual quality worsening. Visual psychophysical testing, automated campimetry and optical coherence tomography contributed findings suggestive of intracranial visual pathway compression. Magnetic resonance imaging of the brain and orbits was indicated to confirm the diagnostic suspicion. Cerebral angiography revealed the presence of an internal carotid artery aneurysm which was treated by endovascular procedure with satisfactory results(AU)

Estudio multicéntrico retrospectivo de los aspectos epidemiológicos, clínicos y terapéuticos de la enfermedad de Kawasaki en niños de Panamá

Resumen Antecedentes: La enfermedad de Kawasaki (EK) representa la principal causa de cardiopatía pediátrica adquirida en muchos países; sin embargo, hay pocos estudios publicados en Latinoamérica. Objetivo: Describir la epidemiología, los aspectos clínicos y el tratamiento de EK en niños en Panamá como parte del estudio de vigilancia de REKAMLATINA-2 en Latinoamérica. Pacientes y Métodos: Estudio retrospectivo, descriptivo, de pacientes internados con diagnóstico de EK, atendidos en tres hospitales pediátricos de Panamá del 1-enero-2009 al 31-diciembre-2013. Resultados: Se analizaron 111 pacientes, 61(54,9%) eran hombres. Todos fueron hospitalizados, siendo la media de hospitalización de 5,8 (4-7) días. La mediana de edad al ingreso fue de 28,9 (12-38) meses. Un 63,9% recibió antimicrobianos recientemente por otros posibles diagnósticos. Recibieron inmunoglobulina intravenosa (IGIV) 105 (94,6%) pacientes; de éstos, 10 (9,5%) fueron resistentes. Un 11,7% tuvo alteraciones cardiovasculares en el ECO inicial, de las cuales las lesiones coronarias se detectaron en 3 (2,9%) pacientes. Conclusiones: Los datos sugieren que EK en Panamá tiene una incidencia cercana a 2,05 x 100,000 bajo 15 años de edad y una frecuencia 2,6 veces mayor bajo 3 años de edad. Se observó un alto porcentaje de uso de antimicrobianos ambulatoriamente antes de la confirmación diagnóstica, lo cual sugiere reconocimiento tardío de EK en Panamá.

Abstract Background: Kawasaki disease (KD) is the leading cause of pediatric acquired heart disease in many countries, however, there are few published studies from Latin America (LA). Aim: To describe the epidemiology, clinical aspects, and treatment of KD in children from Panama as part of the REKAMLATINA-2 in LA. Methods: Retrospective descriptive review of hospitalized patients diagnosed with KD, attended at three main pediatric hospitals of Panama from January-1-2009 to December-31-2013. Results: 111 patients were analyzed, 61(54.9 %) were male. All children were hospitalized, and had a mean length of hospitalization of 5.8 (4-7) days. Median age at admission was 28.9 (12-38) months. Prior to KD final diagnosis, 63.9% patients received antibiotics for other presumed diagnoses. 105 (94.6%) patients received IGIV, 10 (9.5%) were resistant. On initial echocardiogram, 11.7% of cardiovascular complications were reported, of which coronary artery lesions (CALs) were detected in 3 (2.9 %) patients. Conclusion: The data suggest that KD in Panama has an incidence of about 2.05 x 100,000 in children under 15 years of age, and with a frequency 2.6 times higher in children under 3 years. A high rate of antibiotic misuse on outpatient prior to diagnostic confirmation was observed, suggesting KD unawareness and late recognition in Panamá.

Enfermedad de Kawasaki en lactantes bajo un año de edad: un reto para el diagnóstico y tratamiento de los pacientes. Experiencia en un centro hospitalario en México / Kawasaki disease in infants under one year of age: a challenge for the diagnosis and treatment of patients. Experience in a hospital center in Mexico

Resumen Antecedentes: La enfermedad de Kawasaki (EK) en lactantes bajo un año de edad es poco frecuente en la mayoría de los países. Este grupo de pacientes tienen mayor riesgo de desarrollar complicaciones cardiacas. Objetivo: Evaluar el comportamiento clínico, tratamiento empleado y pronóstico cardiaco en lactantes bajo un año de edad atendidos por EK en un hospital pediátrico de tercer nivel en la Ciudad de México. Pacientes y Métodos: Estudio retrospectivo, descriptivo, de pacientes con diagnóstico de EK desde agosto de 1995 a agosto de 2019. Se estudió la presentación clínica, los exámenes de laboratorio, el tratamiento administrado y el desarrollo de lesiones coronarias en pacientes bajo un año de edad y se comparó con pacientes mayores. Resultados: Se estudiaron 687 pacientes, 152 de ellos eran lactantes bajo un año de edad (22,1%). Hubo un mayor tiempo al diagnóstico de la EK en los lactantes menores, con un incremento de presentaciones clínicas incompletas; este grupo de pacientes desarrolló en forma más frecuente lesiones coronarias en comparación con los pacientes mayores y también tuvo un mayor porcentaje de aneurismas coronarios gigantes. Hubo dos fallecimientos en los lactantes menores, secundarios a infarto al miocardio. Conclusiones: El diagnóstico de EK en pacientes bajo un año de edad es un reto diagnóstico con presentaciones clínicas incompletas y mayor riesgo de desarrollar complicaciones cardiacas graves.

Abstract Background: Frequency of Kawasaki disease (KD) in infants is low in almost all countries. These patients are at higher risk of developing cardiac complications. Aim: To evaluate the clinical features, treatment used and cardiac outcome in infants under one year of age attending for KD in a third level pediatric hospital in Mexico City, Mexico. Methods: A cross-sectional study was conducted in our hospital from August 1995 to August 2019. We analyzed the clinical features, laboratory results, treatment used and cardiac outcomes in infants younger than one year of age and compared them with older patients. Results: We included 687 patients, 152 were younger than one year of age (22.1%). There was a delayed diagnosis in younger patients with an increased frequency of incomplete clinical presentations. Coronary artery abnormalities were most common in younger infants who also had an increased frequency of giant coronary artery aneurysms. Two patients in the younger group died in the acute phase of KD of myocardial infarction. Conclusions: Diagnosis of KD in infants younger than 1 year of age is a clinical challenge with an increased rate of incomplete clinical presentations and also an increased risk of development of severe cardiac complications.

Catéter de drenaje de líquido cefalorraquídeo: usos, técnica y complicaciones para el anestesiólogo / Spinal fluid drainage catheter: uses, technique, and complications for the anesthesiologist

Spinal drainage catheter installation is a procedure indicated essentially in the repair of aortic aneurysms and the neurosurgery setting. It is not always a simple procedure where dilemmas arise about the indication, technique, and complications. The following article reviews each of these topics.

La instalación de un catéter de drenaje espinal es un procedimiento indicado principalmente en la reparación de aneurismas aórticos y en el escenario de neurocirugía. No siempre es un procedimiento fácil de realizar donde surgen dudas sobre indicación, técnica y eventuales complicaciones. En el siguiente artículo revisamos cada uno de estos temas.

Effectiveness and safety of structured exercise vs. no exercise for asymptomatic aortic aneurysm: systematic review and meta-analysis / Efetividade e segurança de exercícios estruturados versus sem exercício em pacientes assintomáticos com aneurisma de aorta: revisão sistemática e metanálise

Abstract We conducted a systematic review to compare the effectiveness and safety of exercise versus no exercise for patients with asymptomatic aortic aneurysm. We followed the guidelines set out in the Cochrane systematic review handbook. We searched Medline, Embase, CENTRAL, LILACS, PeDRO, CINAHL, clinicaltrials.gov, ICTRP, and OpenGrey using the MeSH terms "aortic aneurysm" and "exercise". 1189 references were identified. Five clinical trials were included. No exercise-related deaths or aortic ruptures occurred in these trials. Exercise did not reduce the aneurysm expansion rate at 12 weeks to 12 months (mean difference [MD], −0.05; 95% confidence interval [CI], −0.13 to 0.03). Six weeks of preoperative exercise reduced severe renal and cardiac complications (risk ratio, 0.54; 95% CI, 0.31-0.93) and the length of intensive care unit stay (MD, −1.00; 95% CI, −1.26 to −0.74). Preoperative and postoperative forward walking reduced the length of hospital stay (MD, −0.69; 95% CI, −1.24 to −0.14). The evidence was graded as 'very low' level.

Resumo Foi realizada revisão sistemática para comparar a efetividade e a segurança de exercícios versus não exercícios em pacientes assintomáticos com aneurisma de aorta. Usamos os termos MeSH aortic aneurysm e exercise para as bases MEDLINE, Embase, CENTRAL, LILACS, PeDRO, CINAHL, clinicaltrials.gov, International Clinical Trials Registry Platform (ICTRP) e OpenGrey. Foram obtidas 1.189 referências. Cinco ensaios clínicos foram incluídos. Não houve morte ou rotura associada ao exercício. Além disso, este não reduziu a velocidade de crescimento do aneurisma em 12 semanas a 12 meses [diferença de médias (DM) −0,05; intervalo de confiança de 95% (IC95%) −0,13 a 0,03]. Seis semanas de exercícios pré-operatórios reduziram complicações clínicas renais e cardíacas (razão de risco 0,54; IC95% 0,31-0,93) e a permanência em unidade de terapia intensiva (DM −1,00; IC95% −1,26 a −0,74). Caminhadas nos períodos pré e pós-operatório reduziram a permanência hospitalar. A evidência foi classificada como de muito baixa qualidade.
