ABSTRACT

Abstract A primary aortic mural thrombus (PAMT) is defined as a thrombus attached to the aortic wall in the absence of any atherosclerotic or aneurysmal disease of the aorta or any cardiac source of embolus. It is a rare entity that has high morbidity and mortality. There is no consensus on the ideal treatment of PAMT. The objective of this paper is to review the possibilities for treatment of mobile abdominal aortic mural thrombus. Endovascular therapy and open surgery appear to be the best options for treatment of mobile abdominal aortic mural thrombus. Thus, in patients with favorable anatomy, endovascular therapy is probably the treatment choice, while in those with unfavorable anatomy, open surgery is probably the best option for treatment of a mobile abdominal aortic thrombus. It is important to emphasize that anticoagulation alone can be used as a non-aggressive option and, if this fails, endovascular or surgical methods can then be employed.


Resumo O trombo mural aórtico primário é definido como um trombo aderido à parede aórtica na ausência de doença aterosclerótica e/ou aneurismática ou de fonte cardíaca de êmbolo. Trata-se de uma doença rara, porém causadora de alta morbimortalidade, e não há consenso acerca do seu tratamento. Este estudo objetivou revisar as possibilidades na presença de componente móvel. A terapia endovascular e a cirurgia aberta parecem ser as melhores opções, sendo a abordagem endovascular o tratamento de escolha para pacientes com anatomia favorável e a cirurgia aberta o tratamento de escolha para pacientes com anatomia desfavorável. No entanto, a anticoagulação sistêmica apresenta-se como método não invasivo para pacientes com alto risco cirúrgico e como possibilidade terapêutica na falha ou indisponibilidade de abordagem cirúrgica.

ABSTRACT

RESUMEN PROPÓSITO: La pandemia mundial por covid-19 ha impuesto nuevos retos para la atención de pacientes con infarto cerebral con oclusión de gran vaso, el tratamiento endovascular con trombectomía mecánica es la elección para estos casos. Las recomendaciones que se presentan buscan mantener la eficacia, la celeridad y la seguridad de la intervención siguiendo las nuevas medidas de bioseguridad. METODOLOGÍA: Revisión no sistemática de la literatura de manejo endovascular para el infarto cerebral en época pre covid-19 y durante la pandemia por covid-19. Los aspectos de la intervención, que a juicio de los autores se modificaron, se presentan en forma de recomendaciones narrativas. RESULTADOS: Se identificaron tres fases en el manejo endovascular del infarto cerebral: preintervención, intervención y postintervención. En la primera se incluyen los temas de selección del candidato, la tamización para covid-19, el consentimiento informado, la notificación-preparación del equipo y la modalidad anestésica. En las otras dos fases se hacen recomendaciones generales. Por último, se identifican puntos importantes para la toma de decisiones en el manejo endovascular del infarto cerebral. CONCLUSIÓN: Las recomendaciones pretenden facilitar la adaptación de los protocolos, evitar retrasos y mantener la seguridad de la intervención endovascular en pacientes con infarto cerebral con oclusión de gran vaso candidatos a trombectomía mecánica en época de covid-19.


SUMMARY PURPOSE: The global pandemic of COVID-19 has imposed new challenges for the attention of patients with ischemic stroke and large vessel occlusion. Endovascular treatment with mechanical thrombectomy is the therapy of choice for these patients. The recommendations intend to maintain the efficacy, times and safety of the intervention following the new biosafety measures. METHODOLOGY: A non-systematic review of the literature on endovascular management for ischemic stroke in the pre-COVID-19 period and during the COVID-19 pandemic. The aspects of the intervention, modified in the author's opinion, are presented in the form of narrative recommendations. RESULTS: Three phases were identified in the endovascular management for cerebral infarction: Pre-intervention, intervention, and post-intervention. The first one includes candidate selection, screening for COVID-19, informed consent, notification-preparation of the team/suite and anesthetic modality. For the other two phases general recommendations were developed. Finally, we identified key points for decision-making in the endovascular management of ischemic stroke. CONCLUSION: These recommendations pretend to facilitate adaptations of protocols, avoid delays and maintain the safety of endovascular intervention in patients with ischemic stroke with large vessel occlusion candidates for mechanical thrombectomy during COVID-19 pandemic.

ABSTRACT

Objetivo: Revisar sistemáticamente la evidencia de la terapia endovascular comparado con el manejo estándar. Criterios de inclusión: Ensayos clínicos aleatorizados que incluyan a: pacientes adultos mayores de 18 años, haber sufrido accidente cerebrovascular isquémico manejados con terapia endovascular en comparación con manejo médico. Métodos: Se realizó la búsqueda en las siguientes bases de datos: MEDLINE, the Central Register of Controlled Trials (CENTRAL); PubMed, HINARI, EMBASE; Cochrane Injuries group y lista de referencia de los artículos. Resultados: La trombectomía se asoció con disminución de la mortalidad (OR 0,78, IC del 95%: 0,63-0,95 p= 0,01), aumento de la tasa de revascularización (OR 6,16, IC del 95%: 4,39-8,64 p= <0,0001), mejoría de desenlace funcional (OR 1,78, IC del 95%: 1,52 ­ 2,08 p= <0,0001). No hubo diferencia en cuanto a la recurrencia de isquemia cerebral ni de la aparición de hemorragia intracerebral (OR 0,86, IC del 95%: 0,51 ­ 1,47 p= 0,59; OR 1,13, IC del 95%: 0,79 ­ 1,62 p= 0,5, respectivamente). Conclusiones: La terapia endovascular comparada con la fibrinólisis endovenosa mejora el pronóstico funcional, aunque se necesitan más estudios.


Objective: Systematically review the evidence of endovascular therapy compared with standard management. Inclusion criteria: Randomized clinical trials that include adult patients older than 18 years, have suffered an ischemic stroke managed with endovascular therapy compared to medical management. Methods: The search is performed in the following databases: MEDLINE, the Central Registry of Controlled Trials (CENTRAL); PubMed, HINARI, EMBASE; Cochrane Injury Group and reference list of articles. Results: Thrombectomy was associated with decreased mortality (OR 0.78, 95% CI 0.63-0.95 p = 0.01), increased revascularization rate (OR 6.16, CI 95%: 4.39-8.64 p = <0.0001), improvement in functional outcome (OR 1.78, 95% CI: 1.52 - 2.08 p = <0.0001). There was no difference in the recurrence of cerebral ischemia or the appearance of intracerebral hemorrhage (OR 0.86, 95% CI 0.51 - 1.47 p = 0.59, OR 1.13, 95% CI %: 0.79 - 1.62 p = 0.5, respectively). Conclusions: Endovascular therapy compared with the treatment of fibrinolysis improves functional prognosis

ABSTRACT

La terapia endovascular (TEV) es el tratamiento estándar del ataque cerebrovascular isquémico (ACVi) con oclusión de gran vaso (OGVC). Aún no se conoce si esos resultados pueden generalizarse a la práctica diaria. Se describen los resultados de la TEV en pacientes con ACVi por OGVC dentro de las 24 horas, en un análisis retrospectivo entre enero 2013 y diciembre 2017 que incluyó 139 casos consecutivos con ACVi y OGVC en arteria cerebral media (ACM), hasta 24 horas del inicio de los síntomas, que recibieron TEV en nuestra institución. El resultado primario medido fue la escala de Rankin modificada (mRS) ≤ 2 a 90 días. Se evaluaron también: reperfusión exitosa, según la escala modificada de trombólisis en infarto cerebral (mTICI) 2b/3, hemorragia intracraneal sintomática (HIS) y mortalidad a 90 días. La edad media: 67.5 ± 15.0, siendo el 51.8% mujeres. La mediana basal de National Institute of Health Stroke Scale (NIHSS) fue 14 (IIC 8-18); la mediana del tiempo desde inicio de síntomas hasta punción inguinal: 331 min (IIC 212-503). El 45.3%, 63 pacientes, fueron tratados > 6 horas después del inicio de síntomas. La tasa de mRS ≤ 2 fue 47.5%. Se logró una reperfusión exitosa en el 74.8%. La tasa de mortalidad a 90 días fue del 18.7% y la HIS del 7.9%. Nuestro registro de pacientes de la vida real con ACVi por OGVC tratados con TEV dentro de las 24 horas mostró altas tasas de reperfusión, buenos resultados funcionales y pocas complicaciones, acorde con las recomendaciones internacionales.


Endovascular treatment (EVT) has become the standard of care for acute ischemic stroke (AIS) with proximal large vessel occlusions (LVO). However, it is still unknown whether these results can be generalized to clinical practice. We aimed to perform a retrospective review of patients who received EVT up to 24 hours, and to assess safety and efficacy in everyday clinical practice. We performed a retrospective analysis, from January 2013 to December 2017, on 139 consecutive patients with AIS for anterior circulation LVO strokes up to 24 h from symptoms onset, who received EVT in our institution. The primary outcome measured was a modified Rankin scale (mRS) ≤ 2 at 90 days. Secondary outcomes included successful reperfusion, defined as a modified Thrombolysis in Cerebral Infarction (mTICI) scale 2b/3, mortality rate at 90 days and symptomatic intracranial hemorrhage (sICH). The mean age was 67.5 ± 15.0, with 51.8% female patients. Median baseline National Institute of Health Stroke Scale (NIHSS) was 14 (IQR 8-18); median time from symptom onset to groin puncture was 331 min (IQR 212-503). Sixty-three patients (45.3%) were treated beyond 6 hours after symptoms onset. The rate of mRS ≤ 2 was 47.5%. Successful reperfusion was achieved in 74.8 %. Mortality rate at 90 days was 18.7 % and sICH was 7.9 %. Our registry of real-life patients with AIS due to LVO who received EVT within 24 hours showed high reperfusion rates, and good functional results with few complications, according to international recommendations.

ABSTRACT

Introducción: Los aneurismas del segmento comunicante posterior representan aproximadamente 25% de todos los aneurismas intracraneales, y el 50% de los aneurismas de la arteria carótida interna. El objetivo fue evaluar la eficacia del tratamiento quirúrgico y endovascular en el manejo de aneurismas de esta localización. Material y Métodos: Estudio comparativo retrospectivo. Se revisó las historias clínicas de pacientes con aneurisma del segmento comunicante posterior que ingresaron al departamento de Neurocirugía del Hospital Nacional Guillermo Almenara durante el periodo 2010-2017. Se comparó estancia hospitalaria, complicaciones, mortalidad y estado funcional a los 12 meses, en relación al tratamiento recibido, microquirúrgico o endovascular. Resultados: Se evaluaron 256 pacientes, 111 (43,36%) recibieron tratamiento quirúrgico, y 145 (56,64%) endovascular. En el caso de aneurismas rotos, el estado de independencia funcional fue alcanzado por 68 (66,7%) y 69 (70,4%) pacientes que recibieron tratamiento quirúrgico y endovascular, respectivamente (OR:0.84, IC 95%: 0.46­1.53; p=0.505). Se presentaron complicaciones neurológicas en 37 (36,3%) y 34 (34.7%) pacientes sometidos a tratamiento microquirúrgico y endovascular, respectivamente (OR: 1.07, IC 95%: 0.60­1.91; p=0.912). La estancia hospitalaria promedio fue 19,55±13.85 y 14.06±14.97 días, para pacientes con tratamiento quirúrgico y endovascular, respectivamente (p<0.008). La mortalidad fue 11,8% y 11,2%, con ligera predominancia en el grupo tratado quirúrgicamente (OR: 1.05, IC 95%: 0.44­2.52; p=0.904). Conclusiones: No existe diferencia significativa respecto al resultado funcional a los 12 meses, complicaciones y mortalidad entre ambos tipos de tratamiento en el caso de aneurismas rotos. Los pacientes sometidos a terapia endovascular tuvieron de forma significativa menor estancia hospitalaria


Background: Posterior communicating segment aneurysms represent about the 25% of all intracranial aneurysms and the 50% of the internal carotid artery aneurysms. The objective of the study was to evaluate the efficacy of the surgical and endovascular treatments in the management of the aneurysms of this localization. Methods: Comparative and retrospective study. Clinical charts of patients with aneurysms of the posterior communicating segment were reviewed during the period from 2010 to 2017 in the Guillermo Almenara Hospital. Hospital stay, complications, mortality and functional status at 12 months were compared among endovascular and surgical treatment. Results: Two hundred and fifty-six patients were evaluated, 111 (43,36%) were treated with surgery and 145 (54,64%) with endovascular therapy. Among ruptured aneurysms, functional independence status was reached in 68 (66,7%) and 69 (70,4%) of the patients who were treated with surgery and embolization respectively (OR:0.84, IC 95%: 0.46­1.53; p=0.505). Neurological complications were found in 37 (36,3%) and 34 (34,7%) patients treated with surgery and embolization respectively (OR: 1.07, IC 95%: 0.60­1.91; p=0.912). The mean hospital stay was 19,55±13.85 and 14.06±14.97 days of the patients treated with surgery and embolization respectively. Mortality was 11,8% and 11,2%, with a slight predominance in the surgically treated group (OR: 1.05, IC 95%: 0.44­2.52; p=0.904). Conclusions: There is no significant difference according to functional status at 12 months, complications and mortality among both type of treatments in the group of ruptured aneurysms. Patients treated with endovascular therapy had lower hospital stay with statistical difference

ABSTRACT

A correção de aneurisma de aorta abdominal tem sido sua principal indicação o implante de endoprótese (EDV) quando a anatomia for favorável. Apresenta infecção em pós-operatório (PO) baixa, mais relacionados a procedimentos complementares. A ocorrência de fístula aorto-entérica é mais complexa, mas frequentemente associada a infecção pós-EDV. Representa um desafio operatório em um paciente muitas vezes debilitado. A antibioticoterapia é utilizada por longo tempo e de largo espectro. Neste trabalho, apresentaremos um caso de fístula aorto-entérica pós implante de EDV e a conduta que foi realizada para o seu tratamento.


The principal indication for repair of abdominal aortic aneurysm is the endovascular approach when the aortic anatomy is favorable. Graft infection has lower incidence, more related to re-intervations after the endovascular approach. It represents an operational challenge in a often debilitated patient. The antibiotic therapy is long and with a broad spectrum. In this work we will present a case with secondary aortic fistulae after endovascular repair and the decisions for the treatment.

ABSTRACT

La malformación arterio-venosa (MAV) en el páncreas es una anomalía anatómica poco frecuente que puede ser causa de pancreatitis aguda. Presentamos el caso de un paciente de 46 años cuyo diagnóstico se sospechó por los hallazgos de la tomografía computarizada con contraste endovenoso y por resonancia magnética y se confirmó mediante una arteriografía del tronco celíaco y de la arteria mesentérica superior. El tratamiento recibido fue por vía endovascular, aunque la otra opción válida para el tratamiento de esta enfermedad es la resección quirúrgica. El objetivo de esta comunicación es presentar un caso de pancreatitis aguda por MAV tratada por vía endovascular.


Arteriovenous malformation in the pancreas is a rare anatomic abnormality that may produce acute pancreatitis. The diagnosis was suspected by computed tomography with intravenous contrast and by magnetic resonance imaging and it was confirmed by arteriography of the celiac trunk and superior mesenteric artery. The treatment received was endovascular, although the other valid option for the treatment of this disease is the surgical resection. The objective of this communication is to present a case of acute pancreatitis due to arteriovenous malformation treated by endovascular approach.

ABSTRACT

Abstract Background Endovascular management of atherosclerotic infrainguinal arteries recently shifted towards drug eluting devices, designed to locally prevent the restenosis process. Numerous clinical studies report an advantage of drug coated balloons over uncoated balloon angioplasty in treating lower extremity peripheral artery disease. However, as coating and balloon platforms are different, each device requires dedicated clinical evaluations. Objective The aim of the study is to further investigate the safety and effectiveness of a Paclitaxel-Coated Balloon for the treatment of atherosclerotic infrainguinal arteries in a real-world setting. Methods 203 patients out of a final sample of 882 were enrolled in this prospective multicenter, observational, all-comers registry during the first 12 months. The primary endpoints were major adverse events (defined as procedure or device related death within 30 days post index procedure, clinically-driven target lesion revascularization or major target limb amputation) at 6 months and freedom from clinically-driven target lesion revascularization at 12 months. Both endpoints were adjudicated by a Clinical Events Committee. Results Mean patient age was 70.2±10.4 years (60.1% male). 47.3% of the patients were diabetic and 67.5% had a history of smoking. Severe claudication was reported in 37.4% and 40% had critical limb ischemia. 257 lesions, including 13.2% in the infrapopliteal territory, were treated with Passeo-18 Lux (mean lesion length 75.1 mm±69.4, 20% occlusions, 76.3% calcified). At 6 months, the rate of major adverse events was 5.5% (95%CI 3.1-9.7). Freedom from clinically-driven target lesion revascularization at 12 months was 93.2% (95%CI 89.1-95.8). All causes mortality was 6.5% (95%CI 3.8-11.0) and overall amputation rate was 4.2% (95%CI 2.1-8.3) at 12 months. Conclusion In a real-world environment, the BIOLUX P-III registry preliminary results confirm the safety and efficacy of the Paclitaxel-Coated Passeo-18 Lux balloon as a stand-alone treatment option for atherosclerotic infrainguinal arteries.


Resumo Contexto O manejo endovascular de artérias infrainguinais ateroscleróticas recentemente tem mudado para dispositivos farmacológicos, desenhados para impedir localmente o processo de reestenose. Numerosos estudos clínicos descrevem uma vantagem da angioplastia com uso de balões farmacológicos sobre os balões convencionais no tratamento de doença arterial periférica dos membros inferiores. No entanto, considerando que as plataformas do revestimento farmacológico e dos balões são diferentes, cada dispositivo requer avaliações clínicas específicas. Objetivo Fazer investigação adicional sobre a segurança e eficácia de um balão revestido com paclitaxel para o tratamento de artérias infrainguinais ateroscleróticas em um cenário de mundo real. Métodos 203 pacientes de uma amostra final de 882 pacientes foram incluídos neste registro prospectivo observacional multicêntrico de inclusão sequencial, durante os primeiros 12 meses. Os desfechos primários foram eventos adversos maiores (definidos como morte relacionada ao procedimento ou ao dispositivo em até 30 dias após o procedimento-índice, necessidade de revascularização da lesão-alvo ou amputação significativa do membro-alvo) em 6 meses e ausência de de revascularização da lesão-alvo em 12 meses. Ambos os desfechos foram adjudicados por um comitê de eventos clínicos. Resultados A idade média foi 70,2±10,4 anos (60,1% sexo masculino). 47,3% dos pacientes eram diabéticos, e 67,5% tinham história de tabagismo. Claudicação severa foi relatada em 37,4%, e 40% apresentava isquemia crítica de membro. 257 lesões, incluindo 13,2% em território infrapoplíteo, foram tratadas com o balão Passeo-18 Lux (comprimento médio das lesões 75,1 mm±69,4, 20% oclusões, 76,3% calcificadas). Aos 6 meses, a taxa de eventos adversos maiores foi de 5,5% (95%CI 3,1-9,7). A ausência de revascularização da lesão-alvo aos 12 meses foi de 93,2% (95%CI 89,1-95,8). Mortalidade por todas as causas foi de 6,5% (95%CI 3,8-11,0) e a taxa geral de amputação foi de 4,2% (95%CI 2,1-8,3) aos 12 meses. Conclusão Em um cenário de mundo real, os resultados preliminares do registro BIOLUX P-III confirmam a segurança e eficácia do balão revestido com paclitaxel Passeo-18 Lux como opção de tratamento único para artérias infrainguinais ateroscleróticas.

ABSTRACT

Los aneurismas aórticos en la población pediátrica son poco frecuentes. El uso de catéteres de arteria umbilical en neonatos se ha asociado a infección y en algunas oportunidades a formación de aneurismas aórticos. La reparación quirúrgica de estos aneurismas es una forma de terapia; sin embargo, la intervención percutánea con stents pudiese proveer una vía alternativa de tratamiento con menores complicaciones. El objetivo de este reporte es dar a conocer el alcance terapéutico de un procedimiento híbrido, en el que el desarrollo de la técnica quirúrgica y percutánea en conjunto ofrece otra alternativa terapéutica menos invasiva que la cirugía vascular abierta, para la reparación de aneurismas aórticos o de sus ramas principales. Caso clínico: Recién nacido de pretérmino, 30 semanas, peso 1.335 g. Se instaló catéter en arteria umbilicar que se retiró a los 14 días por infección. Evolucionó con sepsis a Staphylococcus aureus. Ecocardiograma y angiotac confirman AAT, se manejó mediante procedimiento híbrido, cirugía e instalación endovascular de 2 stents recubiertos (Atrium V12 XR Medical Corp, Hudson, NH). Los controles clínicos post procedimiento como la ecotomografía abdominal confirmaron el éxito del tratamiento. Conclusión: El procedimiento endovascular de reparación de aneurisma de la aorta en recién nacidos prematuros puede ser considerado en el momento de decir la terapéutica de esta enfermedad y podría evitar los riesgos asociados a cirugía abierta. Sin embargo, obliga a un seguimiento y control durante el crecimiento del paciente por la eventual necesidad de redilatar los stents implantados. Se desconoce cómo será la evolución de los procedimientos endovasculares neonatales en el futuro.


Aortic aneurysms (AA) in the paediatric population are uncommon. The use of umbilical catheters in neonates has been associated with infections and, on some occasions, the formation of aortic aneurysms. The surgical repair of these aneurysms is one type of treatment; however, percutaneous intervention with stents could provide an alternative treatment route, with fewer complications. The aim of this report is to present the therapeutic scope of a hybrid procedure, in which the combined surgical and percutaneous technique offers a less invasive alternative to open surgery for the repair of aortic aneurysms or their main branches. Clinical case: The case concerns a pre-term newborn of 30 weeks weighing 1,335 g. An umbilical catheter was introduced, which was withdrawn at 14 days due to an infection. It developed as Staphylococcus aureus with sepsis. The echocardiogram and Angio-CT confirmed AA, which were managed using a hybrid procedure of surgery and the endovascular implantation of 2 coated stents (Atrium V12 XR Medical Corp, Hudson, NH). The post-procedure clinical follow-ups, including abdominal echo-tomography, confirmed the success of the treatment. Conclusion: The endovascular aortic aneurysm repair procedure in premature newborns may be considered when deciding treatment of this disease, and could avoid the risks associated with open surgery. However, follow-up and monitoring is required while the patient grows up, due to the possibility that the implanted stents require re-dilating. The outcomes of neonatal endovascular procedures in the future are unknown.

ABSTRACT

Objetivo: Describir el caso clínico de una paciente con oclusión de la arteria central de la retina (OACR) bilateral posterior a la embolización de una malformación arterio ­ venosa facial congénita y revisar la literatura sobre el tema. Diseño del estudio: Reporte de caso. Metodología: Se reportó el caso de una paciente con oclusión de arteria central de la retina bilateral que consulta a la clínica Unidad Láser del Atlántico, Barranquilla ­ Colombia en agosto de 2013, se hizo revisión detallada de la historia clínica y se tomaron fotos a color y angiografía fluoresceïnica de la retina. Resultados: La paciente consulta por presentar pérdida de la visión en ambos ojos posterior a una terapia endovascular con embolesferas realizada como tratamiento para una malformación arterio - venosa localizada en la punta de la nariz desde la infancia. La angiografía fluoresceinica de la retina evidencia: 1. Oclusión de la arteria central de la retina bilateral. 2 Persistencia de perfusión en rama superior de bifurcación de arteria temporal inferior ojo derecho 3. Variante anatómica de arteria cilioretiniana ojo izquierdo. Conclusión: La mayoría de las obstrucciones de las arterias centrales de la retina resultan en pérdida severa y permanente de la visión, es por tal motivo que teniendo en cuenta las potenciales complicaciones de origen embólico de los procedimientos intervencionistas, los pacientes necesitan ser conscientes del riesgo que este tratamiento puede implicar. Oftalmólogos, radiólogos y demás personal a cargo de este tipo de procedimientos deben tener un alto índice de sospecha diagnóstica de una OACR ante una disminución repentina de la visión durante o inmediatamente después de este tipo de procedimientos intervencionistas. De igual manera se resalta la necesidad de la evaluación cuidadosa de angiografías para la detección de cualquier vaso colateral anormal antes de la embolización.


Objective: To describe the clinical case of a female patient with central retinal artery occlusion (CRAO) after an embolization procedure as a primary treatment for a congenital nasal vascular lesion, its evolutions and sequela and review the current literature about this subject. Study Design: Case report. Methods: We reported the case of a patient with central retinal artery occlusion, who presented at Clinica Unidad Laser del Atlantico on august 2013. Her medical record was reviewed and analyzed. Posterior segment photographs and fluorescein angiography were taken. Results: The patient was seen for visual loss of both eyes after endovascular therapy for a congenital malformation located at the tip of her nose, which was presented from birth. The fluorescein angiographic showed a central retinal artery occlusion in both eyes. Conclusion: Most of the obstruction of the central retinal arteries result in severe and permanent loss of vision, for that reason and considering account potential embolic complications of interventional procedures, patients need to be aware of the risk that this treatment it may involve. Ophthalmologists, radiologists and other healthcare physicians should have a high index of suspicion of CRAO after a sudden decrease of visual acuity during or immediately after the interventional procedures. Careful evaluation of angiography to detect any abnormal collateral vessel before embolization is recommended.

ABSTRACT

La coartación de aorta es una estrechamiento congénito de la luz aórtica que, generalmente, afecta la porción torácica distal a la emergencia de la arteria subclavia izquierda. Esta condición es de gran importancia, pues predispone al desarrollo de patología cardiovasculares a edades tempranas, lo que se traduce en una alta morbimortalidad. Se reporta el primer caso en Costa Rica, de reparación endovascular de una coartación de aorta, mediante la colocación de un stent recubierto, con parada cardiaca inducida con adenosina. La paciente toleró el procedimiento bien y el gradiente postintervención fue menor de 5 mmHg. Su presión arterial sistémica es 100/60 mmHg y no tiene limitaciones o sintomatología...

ABSTRACT

Los aneurismas de la arteria pulmonar son poco frecuentes en niños. Entre sus principales causas se encuentran procesos infecciosos como la endocarditis, que favorece el desarrollo de aneurismas micóticos, en especial en pacientes con defectos cardíacos congénitos y en aquellos con adicción a drogas de uso endovenoso (sobre todo en adultos), y lleva al desarrollo de aneurismas micóticos. Las opciones de tratamiento dependen de las características de la lesión y de la condición clínica del paciente. Se presenta el caso de una paciente de siete años, quien fue referida para evaluación por endocarditis infecciosa de la válvula tricúspide debida a Staphylococcus aureus. Desarrolló aneurismas bilaterales en ramas lobulares de la arteria pulmonar secundarios a la infección valvular. El aneurisma del lado derecho era de gran tamaño y con alto riesgo de ruptura, razón de peso para que se le efectuara embolización con coils. El procedimiento fue exitoso y no se documentaron complicaciones. La lesión del lado izquierdo se trató de forma expectante teniendo en cuenta que era de menor tamaño. En la actualidad la paciente está en seguimiento ambulatorio con el fin de vigilar la evolución del aneurisma del lado izquierdo.


Pulmonary artery aneurysms are infrequent in children. Among its main causes are infectious processes such as endocarditis which favors the development of mycotic aneurysms especially in patients with congenital heart defects and in those with endovenous drug addiction (mainly in adults) that develop mycotic aneurysms. Treatment options depend on the characteristics of the lesion and the clinical condition of the patient. We present the case of a seven year old female patient who was referred for evaluation of infectious endocarditis of the tricuspid valve due to Staphylococcus aureus. She developed bilateral aneurysms in lobular branches of the pulmonary artery secondary to the valve infection. The right aneurysm was large and had a high risk of rupture, and for this reason an embolization with coils was performed. The procedure was successful and no complications were documented. Given that the left side lesion was smaller, it received an expectant management. At present, the patient has ambulatory follow-up in order to monitor the evolution of the left side aneurysm.

ABSTRACT

Las malformaciones aneurismáticas de la vena de Galeno representan aproximadamente un tercio de todas las malformaciones vasculares intracraneales en la edad pediátrica; sin embargo, existe poca referencia en el medio. Los pacientes con este tipo de malformación presentaban altas tasas de morbimortalidad hasta la década de los noventa; desde entonces el desarrollo en las técnicas de diagnóstico prenatal y de terapia endovascular han permitido modificar el pronóstico de esta población. Se describe el caso de un paciente en quien se hizo diagnóstico prenatal, se realizó tratamiento con terapia endovascular a los cuatro meses de vida, y se obtuvieron buenos resultados. Se hace enfásis en el diagnóstico temprano y en la prevención de secuelas a través de una intervención oportuna.


Aneurysmal malformations of the vein of Galen represent approximately one third of all intracranial vascular malformations in children. However, in our country we have few references. Patients with this type of malformation had high morbi-mortality rates until the early nineties; since then, the development of techniques of prenatal diagnosis and endovascular therapy have allowed to modify the prognosis of these patients. We describe the case of a patient in whom prenatal diagnosis of aneurysmal malformation of the vein of Galen was made, and was managed at four months of age with endovascular therapy with good results. We emphasize on early diagnosis and prevention of sequelae through appropriate intervention.

ABSTRACT

A doença de Behçet, uma vasculite sistêmica de causa desconhecida, pode ser causa de doença aneurismática da aorta em alguns portadores dessa patologia. Nós apresentamos nossa experiência com dois casos de aneurismas aórticos em pacientes com doença de Behçet submetidos à terapêutica endovascular, descrevendo seus respectivos seguimentos. A terapêutica atual, a patofisiologia e os critérios diagnósticos vigentes foram revisados. Concluímos que a técnica endovascular é uma excelente opção terapêutica para certos pacientes com doença de Behçet e que esta deve ser acompanhada de tratamento imunossupressivo adequado.


Behcet's disease, a systemic vasculitis of unknown etiology, may be the cause of aortic aneurysmal diseases in some patients. We report our experience with two Behcet's disease patients who presented with aortic aneurysms and were submitted to endovascular therapy, and describe their respective follow-ups. Current pathophysiology, diagnosis, and treatment approaches were reviewed. Our experience suggests that the endovascular approach, combined with adequate immunosuppressive treatment, is an excellent therapeutic option for some patients with Behcet's disease suffering from aneurysms.

ABSTRACT

Reportamos el uso de la angioplastia percutánea con balón en tres pacientes con diagnóstico de vasoespasmo cerebral secundario a hemorragia subaracnoidea espontánea. Todos los pacientes estaban en mala condición clínica neurológica pero dentro de la ventana terapéutica para isquemia cerebral. El tratamiento fue considerado exitoso tanto en términos angiográficos como clínicos. La terapia endovascular mediante la angioplastia cerebral percutánea con balón es una herramienta útil en el vasoespasmo cerebral, en pacientes debidamente seleccionados y que estén dentro de la ventana terapéutica, que parece ser de doce horas luego de instalados los signos y síntomas.

ABSTRACT

EI vasoespasmo cerebral es la principal causa tratable de muerte e incapacidad por hemorragia subaracnoidea espontánea secundaria a la ruptura de un aneurisma cerebral. Sin embargo, su tratamiento ha sido tradicionalmente frustrante, con resultados desalentadores. A pesar de que aún no se han aclarado del todo los mecanismos fisiopatológicos a través de los cuales ocurre este intrigante fenómeno, en los últimos 9 años, paralelamente al desarrollo de las técnicas endovasculares para el tratamiento de las enfermedades cerebrovasculares, han surgido nuevas alternativas en el manejo del vasoespasmo cerebral. Entre ellas se destacan el uso intraarterial de papaverina y la angioplastia con balón de los vasos cerebrales. Se presenta una revisión del estado actual de estos novedosos instrumentos terapéuticos, así como el reporte de un caso en el cual usamos la papaverina intraarterial en el tratamiento del vasoespasmo quese presentó durante un procedimiento endovascular para excluir un aneurisma de la arteria cerebral media


Cerebral vasospasm is the first treatable cause of death and disability secondary to spontaneous subarachnoid hemorrhage due to ruptured cerebral aneurysms. However, its treatment has been disapointing with poor results. Despite the fact that the physiopathologic mechanisms governing this phenomenon are largely unknown, during the last nine years, simultaneously with the development of endovascular therapy techniques for treatment of cerebrovascular diseases, two new alternatives have emerged in order to alleviate cerebral vasospasm: intraarterial papaverine and cerebral balloon angioplasty. We report the use of intraarterial papaverine in one case to treat cerebral vasospasm presented during the endovascular therapy procedure; a review of literature is included
