ABSTRACT

ABSTRACT Introduction: Tuberculous aortic aneurysm (TBAA) is an exceedingly rare but severe manifestation of tuberculosis, with a high risk of sudden rupture of the aorta in absence of medical or surgical intervention. This review aimed to provide a detailed understanding of TBAA, including its associated complications, affected population, treatment measures, and outcomes. Methods: Case studies and relevant research articles were analyzed to understand the recent advances in medical scientific knowledge on TBAA. Recent clinical case reports on TBAA were searched from the year 2010 to 2020. Results: Case reports indicated a higher prevalence of TBAA in the male population. The most affected age group was 15 to 79 years. The most common treatment for TBAA included surgery followed by antituberculous medication. The case reports discussed in this review reflected open surgery, endovascular repair, coil embolization, laparotomy, aortic valve and root replacement as some of the surgical procedures used depending on the complication and type of aneurysm. The treatment outcome was considered effective in most cases. Conclusion: Postoperative chemotherapy and medications reduce the risk of severity. Early diagnosis of TBAA is imperative, followed by surgical resection and postoperative antituberculous medication with careful follow-up to prevent relapse.

ABSTRACT

ABSTRACT Objective: Tracheoinnominate fistula (TIF) is a rare and frequently lethal complication of tracheostomies. Immediate bleeding control and surgical treatment are essential to avoid death. This report describes the successful endovascular treatment of TIF in a preschooler and reviews the literature concerning epidemiology, diagnosis, prophylaxis, and treatment of TIF in pediatric patients. Case description: A tracheostomized neurologically impaired bed-ridden three-year-old girl was admitted to treat an episode of tracheitis. Tracheostomy had been performed two years before. The child used a plastic cuffed tube continually inflated at low pressure. The patient presented two self-limited bleeding episodes through the tracheostomy in a 48h interval. A new episode was suggestive of arterial bleeding, immediately leading to a provisional diagnosis of TIF, which was confirmed by angiotomography, affecting the bifurcation of the innominate artery and the right tracheal wall. The patient was immediately treated by the endovascular placement of polytetrafluoroethylene (PTFE)/nitinol stents in Y configuration. No recurrent TIF, neurological problems, or right arm ischemia have been detected in the follow-up. Comments: TIF must be suspected after any significant bleeding from the tracheostoma. Endovascular techniques may provide rapid bleeding control with low morbidity, but they are limited to a few case reports in pediatric patients, all of them addressing adolescents. Long-term follow-up is needed to detect whether stent-related vascular complications will occur with growth.


RESUMO Objetivo: As fístulas traqueoinominadas (TIF) são complicações raras e frequentemente letais das traqueostomias (TQT). Controle imediato do sangramento e tratamento cirúrgico são essenciais para evitar a morte. Este trabalho relata o tratamento endovascular bem-sucedido de uma TIF em um pré-escolar e revisa a literatura a respeito da epidemiologia, profilaxia, diagnóstico e tratamento de TIF em pacientes pediátricos. Descrição do caso: Uma criança de 3 anos de idade, com encefalopatia, restrita ao leito e traqueostomizada havia dois anos foi internada para tratar um episódio de traqueíte. A criança usava uma cânula plástica balonada continuamente inflada com baixa pressão. A paciente apresentou dois episódios autolimitados de sangramento pela traqueostomia em um intervalo de 48 horas. Um novo episódio foi sugestivo de sangramento arterial e assumiu-se o diagnóstico provisório de TIF, confirmado através de angiotomografia, atingindo a bifurcação da artéria inominada e a parede direita da traqueia. A paciente foi imediatamente tratada pela inserção endovascular de um enxerto de politetrafluoroetileno (PTFE)/nitinol em "Y". No seguimento, não foram encontradas recorrência de TIF, sequelas neurológicas ou isquemia do braço direito. Comentários: Deve-se suspeitar de TIF sempre que houver um sangramento significativo pelo traqueoestoma. Técnicas endovasculares possibilitam o rápido controle do sangramento com baixa morbidade, mas estão limitadas a poucos relatos de caso e pacientes pediátricos, sendo todos em adolescentes. O seguimento a longo prazo é necessário para avaliar se ocorrem complicações vasculares dos stents com o crescimento.

ABSTRACT

Resumo Pacientes portadores de doença arterial obstrutiva periférica com isquemia crítica do membro associada a infecção de prótese vascular apresentam elevadas taxas morbimortalidade e alto risco de perda do membro. Apresentamos o caso de um paciente masculino de 76 anos com isquemia crítica do membro inferior esquerdo associada a infecção de prótese vascular femoropoplítea. Utilizamos abordagem híbrida para o tratamento com acesso cirúrgico das regiões inguinais e poplíteas, sendo a prótese vascular utilizada como acesso endovascular para recanalização direta da artéria femoral superficial devido a obstrução longa e extensa calcificação, que impediram as tentativas iniciais de tratamento endovascular. Após a recanalização endovascular, a prótese infectada foi retirada. O avanço das técnicas e materiais endovasculares em associação com a cirurgia aberta permitem novas soluções para pacientes quando os procedimentos habituais falham.


Abstract Patients with severe arterial obstructive disease and critical limb ischemia associated with vascular graft infection have elevated morbidity and mortality rates and are at high risk of limb loss. We present the case of a 76-year-old male patient with left lower limb critical ischemia and a femoropopliteal vascular graft infection. We used a hybrid treatment approach with an open surgical approach to the inguinal and popliteal regions and used the vascular prosthesis as endovascular access for direct recanalization of the superficial femoral artery, because the long occlusion and extensive calcification had frustrated initial attempts at endovascular treatment. After endovascular recanalization, the infected graft was removed. Used in conjunction with open surgery, advances in endovascular techniques and materials offer new solutions for patients when usual procedures fail.

ABSTRACT

Abstract Endovascular embolization of arteries feeding pulmonary sequestrations is a growing therapeutic option. A 51-year-old woman with chest pain and hemoptysis was admitted. During hospitalization she presented 150 mL hemoptysis, hypotension, and hematocrit fell to 23.3%. Contrast-enhanced computed tomography confirmed a pulmonary sequestration irrigated by an aneurysmal artery from the abdominal aorta. The patient underwent endovascular coil embolization of the artery feeding the aneurysm and an Amplatzer device was deployed in the proximal third of the sequestration artery. Subsequent contrast-enhanced computed tomography confirmed complete thrombosis of the aberrant artery feeding the aneurysm and absence of irrigation of the pulmonary sequestration. At 56 months follow-up the patient remains asymptomatic, tomography showed involution of the sequestration and complete thrombosis of the aberrant artery. The challenges presented by the different treatment alternatives are discussed.


Resumo A embolização endovascular das artérias que alimentam os sequestros pulmonares é uma opção terapêutica em crescimento. Uma mulher de 51 anos com dor torácica e hemoptise foi internada. Durante a internação, ela apresentou hemoptise de 150 mL, hipotensão e queda do hematócrito para 23,3%. A tomografia computadorizada com contraste confirmou um sequestro pulmonar irrigado por uma artéria aneurismática originária da aorta abdominal. A paciente foi submetida a embolização endovascular da artéria que alimentava o aneurisma com uso de coils e dispositivo Amplatzer no terço proximal da artéria sequestrante. A tomografia subsequente confirmou a trombose completa da artéria aberrante que alimentava o aneurisma e a ausência de irrigação dentro do sequestro pulmonar. No seguimento de 56 meses, a paciente permanecia assintomática, e a tomografia mostrou involução do sequestro e trombose completa da artéria aberrante. Os desafios apresentados pelas diferentes alternativas de tratamento são discutidos neste artigo.

ABSTRACT

Objective To report three cases of vein of Galen aneurysmalmalformation (VGAM) in pediatric patients treated at the hemodynamics lab of Hospital Santa Isabel (HSI) in Blumenau, state of Santa Catarina, Brazil, from 2006 to 2020. Clinical presentation, endovascular treatment, and postprocedure evolution to date are included. Case description Three children aged 5 to 12 months with cardiac, respiratory, or neurological damage in the neonatal stage, were referred to the neurosurgery service and diagnosed with VGAM. The three patients underwent endovascular embolization of themalformation, with different clinical evolution throughout outpatient follow-up. Conclusion Vein of Galen aneurysmal malformations are uncommon vascular abnormalities that, until the advent of endovascular embolization, were associated with high morbidity and mortality rates. Its prognosis is linked with initial clinic, early diagnosis, and timely surgical correction.

ABSTRACT

ABSTRACT Background: Predictors of outcomes following endovascular treatment (ET) for aneurysmal subarachnoid hemorrhage (aSAH) are not well-defined. Identifying them would be beneficial in determining which patients might benefit from ET. Objective: To identify the predictive factors for poor outcomes following ET for aSAH. Methods: 120 patients with ruptured cerebral aneurysms underwent endovascular embolization between January 2017 and December 2018. Blood pressure variability was examined using the standard deviation of the 24-hour systolic blood pressure (24hSSD) and 24-hour diastolic blood pressure (24hDSD). Predictors were identified through univariate and multivariate regression analysis. All patients were followed up for three months. Results: At follow-up, 86 patients (71.7%) had good outcomes and 34 (28.3%) had poor outcomes. Patients with poor outcomes had significantly higher 24hSSD than those with good outcomes (19.3 ± 5.5 vs 14.1 ± 4.8 mmHg; P < 0.001). The 24hDSD did not differ significantly between patients with good outcomes and those with poor outcomes (9.5 ± 2.3 vs 9.9 ± 3.5 mmHg; P = 0.464). The following were significant risk factors for poor outcomes after endovascular embolization: age ≥ 65 years (odds ratio [OR] = 23.0; 95% confidence interval [CI]: 3.0-175.9; P = 0.002); Hunt-Hess grade 3-4 (OR = 6.8; 95% CI: 1.1-33.7; P = 0.039); Fisher grade 3-4 (OR = 47.1; 95% CI: 3.8-586.5; P = 0.003); postoperative complications (OR = 6.1; 95% CI: 1.1-34.8; P = 0.042); and 24hSSD ≥ 15 mmHg (OR = 14.9; 95% CI: 4.0-55.2; P < 0.001). Conclusion: Elevated 24hSSD is a possibly treatable predictive factor for poor outcomes after ET for aSAH.


RESUMO Antecedentes: Fatores preditores de resultados após tratamento endovascular (TE) para hemorragia subaracnóide aneurismática (HSA) não estão bem definidos. Identificá-los seria útil para determinar quais pacientes podem se beneficiar de TE. Objetivo: Identificar os fatores preditivos de resultados ruins após TE para HSA. Métodos: 120 pacientes com aneurismas cerebrais rompidos foram submetidos à embolização endovascular entre janeiro de 2017 e dezembro de 2018. A variabilidade da pressão arterial foi examinada usando-se o desvio padrão da PA sistólica de 24 horas (DPPAS- 24h) e da PA diastólica de 24 horas (DPPAD-24h). Os fatores preditores foram identificados por meio de análises de regressão univariada e multivariada. Todos os pacientes foram acompanhados por três meses. Resultados: No acompanhamento, 86 pacientes (71,7%) tiveram bons resultados e 34 (28,3%) tiveram resultados ruins. Pacientes com resultados ruins apresentaram DPPAS-24h significativamente maior do que aqueles com bons resultados (19,3 ± 5,5 vs 14,1 ± 4,8 mmHg; P <0,001). O DPPAD-24h não diferiu significativamente entre os pacientes com bons resultados e aqueles com resultados ruins (9,5 ± 2,3 vs 9,9 ± 3,5 mmHg; P = 0,464). Os fatores de risco significativos para resultados ruins após embolização endovascular foram os seguintes: idade ≥ 65 anos (razão de probabilidade [OR] = 23,0; intervalo de confiança de 95% [IC]: 3,0-175,9; P = 0,002); escala de Hunt-Hess 3-4 (OR = 6,8; IC 95%: 1,1-33,7; P = 0,039); escala de Fisher 3-4 (OR = 47,1; IC 95%: 3,8-586,5; P = 0,003); complicações pós-operatórias (OR = 6,1; IC 95%: 1,1-34,8; P = 0,042); e DPPAS 24h ≥ 15 mmHg (OR = 14,9; IC 95%: 4,0-55,2; P <0,001). Conclusão: O DPPAS 24h elevado é um fator preditivo possivelmente tratável para resultados ruins após TE para HSA.

ABSTRACT

Abstract Carotid artery trauma carries a high risk of neurological sequelae and death. Surgical management of these injuries has been controversial because it entails deciding between repair or ligation of the vessel, for which there is still no true consensus either way. This article proposes a new management strategy for carotid artery injuries based on the principles of damage control surgery which include endovascular and/or traditional open repair techniques. The decision to operate immediately or to perform further imaging studies will depend on the patient's hemodynamic status. If the patient presents with massive bleeding, an expanding neck hematoma or refractory hypovolemic shock, urgent surgical intervention is indicated. An altered mental status upon arrival is a potentially poor prognosis marker and should be taken into account in the therapeutic decision-making. We describe a step-by-step algorithmic approach to these injuries, including open and endovascular techniques. In addition, conservative non-operative management has also been included as a potentially viable strategy in selected patients, which avoids unnecessary surgery in many cases.


Resumen El trauma de la arteria carótida tiene una alta probabilidad de muerte y de secuelas neurológicas. El manejo quirúrgico es objeto de controversia porque se tiene que decidir entre reparar la arteria carótida o ligarla, para lo cual aún no existe un consenso. El objetivo de este artículo es proponer una nueva estrategia de manejo para el trauma de la arteria carótida con los principios de la cirugía de control de daños y el uso de técnicas como el reparo endovascular o el manejo conservador. La decisión de operar el paciente inmediatamente o realizar estudios imagenológicos dependerá del estado hemodinámico del paciente. Si el paciente presenta sangrado masivo, hematoma expansivo o choque hipovolémico refractario, una intervención quirúrgica urgente esta indicada. Un déficit del estado neurológico al ingreso es un marcador de mal pronóstico en estos casos e influye en la toma de decisiones. Se describe el paso a paso del reparo vascular abierto y se incluye las estrategias de manejo tanto endovasculares como abiertas. Adicionalmente, el manejo conservador también ha sido incluido como una estrategia viable en pacientes seleccionados, evitando cirugías innecesarias.

ABSTRACT

Abstract Peripheral vascular injuries are uncommon in civilian trauma but can threaten the patient's life or the viability of the limb. The definitive control of the vascular injury represents a surgical challenge, especially if the patient is hemodynamically unstable. This article proposes the management of peripheral vascular trauma following damage control surgery principles. It is essential to rapidly identify vascular injury signs and perform temporary bleeding control maneuvers. The surgical approaches according to the anatomical injured region should be selected. We propose two novel approaches to access the axillary and popliteal zones. The priority should be to reestablish limb perfusion via primary repair or damage control techniques (vascular shunt or endovascular approach). Major vascular surgeries should be managed post-operatively in the intensive care unit, which will allow correction of physiological derangement and identification of those developing compartmental syndrome. All permanent or temporary vascular procedures should be followed by a definitive repair within the first 8 hours. An early diagnosis and opportune intervention are fundamental to preserve the function and perfusion of the extremity.


Resumen El trauma vascular periférico no es común en el contexto civil, pero representa una amenaza para la vida del paciente o de la extremidad. El control definitivo de la lesión vascular representa un desafío quirúrgico, especialmente en pacientes con inestabilidad hemodinámica. Este artículo describe la propuesta de manejo del trauma vascular periférico de acuerdo con los principios de la cirugía de control de daños. Se debe identificar los signos sugestivos de lesión vascular y realizar oportunamente maniobras temporales para el control del sangrado. Se debe elegir el abordaje quirúrgico dependiendo del área anatómica lesionada. Se proponen dos nuevas incisiones para acceder a la región axilar y poplítea. La prioridad es restablecer la perfusión de la extremidad mediante el reparo primario o técnicas de control de daños (shunt vascular o abordaje endovascular). Los pacientes sometidos a cirugías vasculares mayores deben ser manejados postoperatoriamente en la unidad de cuidados intensivos para corregir las alteraciones fisiológicas e identificar aquellos que desarrollen un síndrome compartimental. Todos los procedimientos vasculares permanentes o temporales deben contar con un reparo definitivo en las primeras 8 horas. El diagnóstico temprano e intervención oportuna son fundamentales para salvaguardar la perfusión y funcionalidad de la extremidad.

ABSTRACT

Abstract Trauma damage control seeks to limit life-threatening bleeding. Sequential diagnostic and therapeutic approaches are the current standard. Hybrid Room have reduced hemostasis time by integrating different specialties and technologies. Hybrid Rooms seek to control bleeding in an operating room equipped with specialized personnel and advanced technology including angiography, tomography, eFAST, radiography, endoscopy, infusers, cell retrievers, REBOA, etc. Trauma Hybrid Service is a concept that describes a vertical work scheme that begins with the activation of Trauma Code when admitting a severely injured patient, initiating a continuous resuscitation process led by the trauma surgeon who guides transfer to imaging, angiography and surgery rooms according to the patient's condition and the need for specific interventions. Hybrid rooms integrate different diagnostic and therapeutic tools in one same room, reducing the attention time and increasing all interventions effectiveness.


Resumen El control de daños en trauma busca limitar el sangrado que amenaza la vida. El enfoque diagnóstico y terapéutico secuenciales son el estándar actual. Las salas híbridas que integran especialidades y tecnologías han reducido el tiempo de hemostasia. Las salas híbridas buscan controlar el sangrado en un quirófano equipado con personal especializado y tecnología de punta como sistemas de angiografía, tomografía, eFAST, radiografía, endoscopia, infusores, recuperadores de células, REBOA, etc. El concepto del servicio hibrido de atención de trauma integra un trabajo vertical que inicia con la activación del código de trauma al admitir un paciente traumatizado grave, iniciando los esfuerzos de reanimación dirigida por el cirujano de trauma que orienta el traslado a salas de imágenes, angiografía y cirugía según la condición del paciente y la necesidad de intervenciones específicas. Las salas hibridas le permite al cirujano de trauma tener todas estas herramientas tanto diagnosticas como terapéuticas al alcance de una sola sala, reduciendo el tiempo de atención y aumentando la efectividad de las intervenciones realizadas.

ABSTRACT

RESUMEN La dilación aneurismática de la aorta es una patología con una prevalencia importante entre las afecciones que aquejan a la misma (dependiendo de la zona que compromete) sea aorta torácica o abdominal presenta una mortalidad variable que exige distintas y específicas formas de reparación acorde a la factibilidad técnica y la fragilidad del paciente. La angiografía por tomografía computada o por resonancia magnética son los exámenes de elección para el diagnóstico diferencial de las distintas patologías de la aorta, aportando detalles estructurales para trazar estrategias en relación a técnicas a emplear para su abordaje o reparación. Entre las múltiples opciones terapéuticas para las dilataciones aneurismáticas que comprometen a la aorta torácica, la reparación endovascular de los aneurismas se han convertido en una opción terapéutica muy viable para proporcionar una menor comorbilidad frente a la reparación quirúrgica a cielo abierto, aun en situaciones muy complejas en donde pudieran coexistir un compromiso de ramas aórticas importantes, en estos casos la reparación endovascular de los aneurismas continua siendo de elección al poder ser complementada con una revascularización quirúrgica mínima en forma previa o concomitante, constituyéndose así en una técnica híbrida eficaz y eficiente. El actual trabajo presenta a un paciente con el diagnóstico de sífilis terciaria en quien se evidencia un compromiso importante de la aorta torácica, consistente en una dilatación aneurismática en su porción descendente que comprime extrínsecamente el nacimiento de las arterias: carótida primitiva y subclavia izquierda. Se realizó en un primer tiempo un puente carótido-carotídeo y en un segundo tiempo el tratamiento endovascular consistente en el implante de una endoprótesis por vía femoral hasta la lesión en la aorta torácica, los mismos sin compromiso de la circulación de los vasos del cuello preservando la indemnidad de la circulación cerebral y lográndose una exclusión exitosa del aneurisma torácico con la endoprótesis.


ABSTRACT The aneurysmal dilation of the aorta is a pathology with a significant prevalence among the conditions that afflict it, depending on the area involved, whether thoracic or abdominal aorta has a variable mortality that requires different and specific forms of repair according to the technical feasibility and fragility of the patient. Computed tomography angiography or magnetic resonance angiography are the tests of choice for the differential diagnosis of the different pathologies of the aorta, providing structural details to design strategies in relation to techniques to be used for its approach or repair. Among the multiple therapeutic options for aneurysmal dilatations involving the thoracic aorta, endovascular repair of aneurysms have become a very viable therapeutic option by providing less comorbidity compared to open surgical repair, even in very complex situations where important aortic branches may coexist, in these cases endovascular repair of aneurysms continues to be of choice as it can be complemented with minimal surgical revascularization either previously or concomitantly, thus constituting an effective and efficient hybrid technique. This work presents a patient with the diagnosis of tertiary syphilis in whom a significant compromise of the thoracic aorta is evidenced, consisting of an aneurysmal dilatation in its descending portion that extrinsically compresses the origin of the arteries: primitive carotid and left subclavian. A carotid:carotid bridge was performed firstly and in the femoral route until the lesion in the thoracic aorta, the same without compromising the circulation of the vessels of the neck preserving the indemnity of the cerebral circulation and achieving a successful exclusion of the thoracic aneurysm with the endoprosthesis.

ABSTRACT

Abstract Introduction: The treatment of infrarenal aortic aneurysms has changed in the last three decades. Endovascular aneurysm repair (EVAR) has become the primary treatment option in anatomically suitable patients with infrarenal aortic aneurysms. However, there is no serum biomarker to be used in EVAR follow-up. Methods: This is a prospective single-centre study of 30 consecutive patients with abdominal aortic aneurysm (AAA) who underwent EVAR. Serum dosages of micro ribonucleic acid 1281 (miRNA-1281), creatinine, total cholesterol, triglycerides, and C-reactive protein (CRP) were evaluated and angiotomographic evaluations were performed preoperatively and six months after the intervention. Results: There was a hyperexpression of miRNA-1281 in patients with AAA and a significant reduction of it after EVAR, from 1.66-fold before EVAR to 0.27 after the procedure (P<0.0001). MiRNA-1281 expression was not influenced by renal function (creatinine: 1.14±0.29, P=0.68), total cholesterol (179.9±59.9, P=0.22), or CRP (1.17±3.5; P=0.48). There is correlation between AAA size and CRP serum levels, however there was no statically significant reduction of CRP after EVAR. Discussion: MiRNA-1281 expression may be influenced by cholesterol, triglycerides levels, and renal function. We found no difference in these markers before and six months after EVAR. However, miRNA-1281 presents a significant reduction in patients with no follow-up complications. We hypothesize that miRNA-1281 expression may be related to aortic wall stress or flow changes. Conclusion: MiRNA-1281 may contribute as a possible marker of EVAR follow-up.

ABSTRACT

Introducción. La presión arterial sistólica puede ser un factor determinante para la toma de decisiones en el manejo de pacientes con trauma severo y hemorragia no compresible del torso. El objetivo de este trabajo fue determinar el punto óptimo de presión arterial sistólica previo a la oclusión endovascular de aorta asociado con la mortalidad a las 24 horas. Métodos. Se realizó un análisis combinado de dos bases de datos de registro de REBOA, ABO-Trauma Registry y AAST-AORTA, que incluye pacientes de Norte América, Suramérica, Europa, Asia y África. Pacientes sin efecto hemodinámico con el uso del REBOA fueron excluidos. Se describieron las características demográficas, clínicas y de la colocación del REBOA en los pacientes que fallecieron en las primeras 24 horas. Se analizó la asociación entre la presión arterial sistólica previa a la oclusión aortica y la mortalidad a través de modelos de regresión logística y se evaluó el poder predictivo de la presión arterial sistólica en un intervalo entre 60 y 90 mmHg. Resultados. Fueron identificados 871 registros, pero solo 693 pacientes cumplieron con los criterios de inclusión. El trauma cerrado se presentó en el 67,2 % de los pacientes y la severidad del trauma tuvo una mediana de ISS de 34 (RIQ: 25-45). La mediana de la presión arterial sistólica previa al REBOA fue de 61 mmHg (RIQ: 46-80). La mortalidad a las 24 horas fue del 34,6 %. La asociación entre la presión arterial sistólica pre-oclusión de la aorta y la mortalidad a las 24 horas tiene una capacidad predictiva de acuerdo con el área bajo la curva ROC para trauma cerrado de 0,64 (IC95% 0,59-0,70) y para trauma penetrante de 0,61 (IC95% 0,53-0,69). Se identificó que la presión arterial sistólica de 70 mmHg se asocia con un aumento por encima del 25 % de la mortalidad a las 24 horas. Discusión. La presión arterial sistólica de 70 mmHg en pacientes con trauma severo y hemorragia no compresible puede ser el punto crítico para la oclusión endovascular de aorta para mejorar la supervivencia de los pacientes, sin importar el mecanismo de trauma. Sin embargo, la presión arterial sistólica debe complementarse con otros factores clínicos para tomar la decisión oportuna


Introduction. Systolic blood pressure (SBP) can be a determining factor for decision-making in the management of patients with severe trauma and non-compressible torso bleeding (NTCH). The objective of this study was to determine the optimal SBP threshold value prior to endovascular occlusion of the aorta associated with 24-hour mortality.Methods. A combined analysis of two REBOA registry databases, ABO-Trauma Registry and AAST-AORTA, was performed, which includes patients from North America, South America, Europe, Asia, and Africa. Patients without hemodynamic effect with the use of REBOA were excluded. Demographic, clinical, and REBOA placement characteristics were described in patients who died in the first 24 hours. The association between SBP prior to aortic occlusion and mortality was analyzed using logistic regression models and the predictive power of SBP was evaluated in an interval between 60 and 90 mmHg.Results. 871 records were identified, but only 693 patients met the inclusion criteria. Blunt trauma occurred in 67.2% of the patients and the severity of the trauma had a median ISS of 34 (IQR: 25-45). The median systolic blood pressure prior to REBOA was 61 mmHg (IQR: 46-80). The 24-hour mortality was 34.6%. The association between systolic blood pressure pre-occlusion of the aorta and mortality at 24 hours has a predictive capacity according to the area under the ROC curve for blunt trauma of 0.64 (95% CI: 0.59-0.70) and for penetrating trauma of 0.61 (95% CI: 0.53-0.69). A systolic blood pressure of 70 mmHg was found to be associated with an increase of over 25% in mortality at 24 hours. Discussion. SBP of 70 mmHg in patients with severe trauma and non-compressible hemorrhage may be the critical point for endovascular aortic occlusion to improve patient survival, regardless of the mechanism of trauma. However, systolic blood pressure must be supplemented with other clinical factors to make the timely decision

ABSTRACT

Abstract Objective: To validate the use of a three-dimensional printing system for metric and volumetric analysis of the segments of an abdominal aortic aneurysm (AAA). Materials and Methods: In patients scheduled to undergo endovascular AAA repair, the computed tomography angiography (CTA) measurements obtained during the preoperative assessment of the patients were compared with those obtained by computed tomography of individualized three-dimensional biomodels. Results: The volumetric assessment showed a discrepancy of 3-12%, and the difference between the areas was 10-16%. Conclusion: Computed tomography measurements of 3D-printed biomodels of AAAs appear to be comparable to those of threedimensional CTA measurements of the same AAAs, in terms of the metric and volumetric dimensions.

ABSTRACT

Objective:To investigate the clinical efficacy of thoracic endovascular aortic repair (TEVAR) in treating Stanford type B traumatic aortic dissection (TAD).Methods:A retrospective case series study was conducted to analyze the clinical date of 26 patients with Stanford type B TAD admitted to Nantong First People's Hospital from June 2011 to December 2019. There were 21 males and 5 females, aged 35-83 years [(56.2±12.9)years]. All patients mainly suffered from chest and back trauma and were treated with TEVAR. The operation time, intraoperative blood loss, intraoperative heparin dosage, duration of ICU stay and postoperative organ complications were collected. The changes of brain natriuretic peptide, urea nitrogen and creatinine were compared before operation and at one day after operation. The CT angiography (CTA) was performed to mainly detect the location of stent, reverse tearing, paraplegia and internal leakage at 6 months after TEVAR. The aortic CTA was used to measure the maximum diameter of aortic dissecting aneurysm and true lumen diameter of distal aorta before operation and at 6 months after operation, and the diameter changes were compared to determine the aortic remodeling after TEVAR.Results:All patients were followed up for 6-36 months [(25.9±6.3)months]. The operation time was 60-200 minutes [(96.7±30.7)minutes], the intraoperative blood loss was 20-45 ml [(31.1±6.8)ml], the dosage of heparin was 0-0.53 mg/kg [(0.4±0.1)mg/kg], the postoperative ICU stay was 1-7 days [(4.7±1.3)days]. Seven patients developed pulmonary infections after operation and showed significant improvement after closed thoracic drainage, airway management and anti-infection treatment. Two patients had abnormal renal function after operation and received medical therapy for improvement. There was no significant difference in brain natriuretic peptide, urea nitrogen and creatinine between before operation and one day after operation ( P>0.05). At 6 months after operation, the CTA showed that the stent position was satisfactory and there were no serious complications such as reverse tearing and paraplegia. Of one patient with type I endoleak, the tumor did not further expand and his condition was stable. At 6 months after operation, the diameter of dissecting aneurysm [(34.4±5.0)mm] was smaller than that before operation [(38.2±5.6)mm], the true lumen of distal stent [(26.8±4.6)mm] was larger than that before operation [(22.6±6.0)mm] ( P<0.05 or 0.01). Conclusion:For Stanford type B TAD, TEVAR has no significant effect on cardiac function and renal function, with no severe complications and good aortic remodeling.

ABSTRACT

Patients with chronic kidney dysfunction (CKD) have abnormal coagulation function and impaired drug metabolism, resulting in increased bleeding risk and decreased drug clearance. Therefore, while receiving treatment, the prognosis of ischemic stroke patients with CKD is different from that of ischemic stroke patients without CKD. For patients with CKD who need anticoagulant treatment, the use of new anticoagulants without renal metabolism can achieve the same anticoagulant effect as warfarin, and the risk of bleeding is lower. When using antiplatelet drugs, due to the increased risk of bleeding in ischemic stroke patients with CKD, the clinical benefits and bleeding risk should be carefully weighed. Although CKD is not an absolute contraindication of intravenous thrombolysis or endovascular treatment in patients with acute ischemic stroke, attention should be paid to the influence of CKD on the increased risk of death in patients with ischemic stroke after treatment.
