Non-cirrhotic portal vein thrombosis - therapeutic challenge.

Portal vein thrombosis (PVT) is a disease in which thrombosis occurs from the intrahepatic branches of the portal vein, and may extend to the splenic vein and/or superior mesenteric vein. It is most often associated with liver cirrhosis. PVT not associated with cirrhosis is rare. The aim of this article is to report two cases of PVT in which it was not associated with cirrhosis. Both were treated with anticoagulation and clinical progress afterwards was good.

Trombose de veia porta não associada à cirrose - desafio terapêutico / Non-cirrhotic portal vein thrombosis - therapeutic challenge

Resumo A trombose de veia porta (TVP) é uma doença na qual ocorre trombose desde os ramos intra-hepáticos da veia porta, podendo se estender até a veia esplênica e/ou veia mesentérica superior, estando associada, na maioria das vezes, à cirrose hepática. A TVP não associada a cirrose é rara. O objetivo deste artigo foi relatar dois casos de TVP não associados à cirrose, que foram tratados com anticoagulação e tiveram evolução clínica satisfatória.

Axillary-iliac bypass to protect a transplanted kidney during abdominal aortic aneurysm repair: case report.

Abdominal aortic aneurysms (AAA) are the most common type, even when compared to those involving other segments of the aorta. The prevalence and natural history of arterial aneurysms in abdominal organ transplant recipients remain uncertain. We report a case of abdominal aortic aneurysm in a kidney transplant patient with contrast allergy. Conventional abdominal aortic aneurysm repair was performed, constructing a bi-iliac aortic bypass. A temporary bypass was constructed from the right axillary artery to the right common iliac artery to maintain the renal graft. The patient was transferred to the intensive care unit, where he remained hemodynamically stable, and he was discharged on the 2nd postoperative day. Conventional open surgery with temporary extra-anatomic bypass is an alternative option for treatment of AAA in patients with transplanted kidneys.

Derivação axilo-ilíaco para proteção de rim transplantado durante a correção de aneurisma de aorta abdominal: relato de caso / Axillary-iliac bypass to protect a transplanted kidney during abdominal aortic aneurysm repair: case report

Resumo Os aneurismas de aorta abdominal (AAA) são os mais frequentes, mesmo quando comparados a outros segmentos da aorta. A prevalência e a história natural de aneurismas arteriais em receptores de transplante de órgão abdominal permanecem incertas. Relatamos a abordagem de um caso de aneurisma de aorta abdominal em um paciente transplantado renal e com alergia ao contraste. Foi realizado o tratamento convencional do aneurisma de aorta abdominal com um by-pass aorto bi-ilíaco. Para manutenção do enxerto renal, foi confeccionado um by-pass temporário da artéria axilar direita até a artéria ilíaca comum direita. O paciente foi encaminhado para a unidade de terapia intensiva, onde permaneceu estável hemodinamicamente e recebeu alta no 2º pós-operatório. A cirurgia convencional aberta com derivação extra-anatômica temporária é uma alternativa para o tratamento do AAA em pacientes com transplante renal.

Endovascular treatment of traumatic dissection of the thoracic aorta - series of 16 cases.

BACKGROUND: Aortic injuries caused by blunt chest traumas have high pre-hospital and emergency mortality. The endovascular approach is one option for treatment of these injuries, but many outcomes related to this approach remain unknown. OBJECTIVES: The aim of this study is to describe a specialist trauma center's experience with endovascular treatment of cases like these. METHODS: This is a descriptive study based on review of the electronic medical records of patients who had suffered from blunt thoracic aorta trauma and were seen at a hospital specializing in trauma cases in the city of Curitiba (Paraná, Brazil). RESULTS: Sixteen patients were included in the study. All patients were traffic accident victims and 75% of the accidents were the result of vehicle collisions. Aortic lesions ranged from grade I to IV and the majority had grade II lesions (50%). All patients underwent endovascular treatment with endografts, an average of 71 hours after the trauma. Two patients died, both from causes unrelated to their aortic injuries. During follow-up, only two patients presented complications (endoleak and progression of the dissection). CONCLUSIONS: The endovascular method is a viable alternative for treatment of blunt trauma thoracic aortic injuries. Randomized and controlled studies are needed to provide evidence to support indication of this method to treat this type of injury.

Endovascular treatment of penetrating thoracic aorta injury - case report.

In the current scenario, traumas with violent causes are responsible for large numbers of cases. Among these, thoracic aorta injury caused by penetrating trauma is a cause of elevated morbidity and mortality, demanding adequate diagnosis, and can now often be repaired using endovascular procedures. This treatment method has proven to be safer, with a lower rate of complications than open surgical procedures. After endovascular repair, it is necessary to conduct continuous monitoring of the patient's health and correct any complications related to the procedure that may emerge. The objective of this article is to describe a case of penetrating trauma of the thoracic aorta that was treated endovascularly, since the literature predominantly covers blunt trauma injuries.

Abordagem endovascular de lesão de aorta torácica penetrante - relato de caso / Endovascular treatment of penetrating thoracic aorta injury - case report

Resumo O cenário atual do trauma por causas violentas tem apresentado um elevado número de casos. Entre eles, a lesão de aorta torácica por trauma penetrante é uma condição de elevada morbimortalidade que exige diagnóstico adequado e que, nos últimos anos, tem sido corrigida com procedimentos endovasculares. Essa modalidade de tratamento se mostra mais segura, com menor número de complicações em relação ao procedimento cirúrgico aberto. Após a realização da abordagem endovascular, há necessidade de acompanhamento contínuo, que visa monitorar as condições de saúde do paciente e corrigir possíveis complicações relacionadas ao procedimento. O objetivo deste artigo é relatar um caso de traumatismo penetrante de aorta torácica, tratado por via endovascular, visto que a literatura aborda predominantemente as lesões por trauma contuso.

Tratamento endovascular de dissecção traumática de aorta torácica - série de 16 casos / Endovascular treatment of traumatic dissection of the thoracic aorta - series of 16 cases

Resumo Contexto As lesões de aorta nos traumatismos torácicos fechados possuem alta mortalidade pré-hospitalar e no serviço de emergência. O tratamento endovascular é um método de escolha para o tratamento dessas lesões; entretanto, muitos resultados em relação a essa abordagem permanecem desconhecidos. Objetivos O objetivo deste trabalho é descrever a experiência no tratamento endovascular de lesões traumáticas de aorta torácica em um centro de referência em trauma. Métodos Este trabalho trata-se de estudo descritivo realizado através da revisão de prontuários eletrônicos de pacientes vítimas de trauma contuso de aorta torácica, atendidos em um hospital de referência em trauma na cidade de Curitiba (Paraná, Brasil). Resultados Dezesseis pacientes foram incluídos no estudo. Todos os pacientes foram vítimas de acidente de trânsito, sendo que 75% dos acidentes ocorreram por colisão entre veículos. As lesões de aorta variaram de Grau I a IV, e a maioria dos pacientes apresentou lesão de grau II (50%). Todos os pacientes foram submetidos a terapia endovascular com implante de endoprótese sendo realizado em média 71 horas após o trauma. Dois pacientes evoluíram a óbito, porém de causas não relacionadas à lesão de aorta. Durante o seguimento, apenas dois pacientes apresentaram complicações (endoleak e progressão da dissecção). Conclusões O método endovascular é uma alternativa viável no tratamento de lesões de aorta torácica por trauma contuso. São necessários estudos randomizados e controlados a fim de reforçar a indicação desse método como terapia para esse tipo de lesão.
