Abstract

Background:Endovascular repair has become established as a safe and effective method for treatment of abdominal aortic aneurysms. One major complication of this treatment is leakage, or endoleaks, of which type 2 leaks are the most common.Objective:To conduct a brief review of the literature and evaluate the safety and effectiveness of embolization by micronavigation for treatment of type 2 endoleaks.Method:A review of medical records from patients who underwent endovascular repair of abdominal aortic aneurysms identified 5 patients with persistent type 2 endoleaks. These patients were submitted to embolization by micronavigation.Results:In all cases, angiographic success was achieved and control CT scans showed absence of type 2 leaks and aneurysm sacs that had reduced in size after the procedure.Conclusion:Treatment of type 2 endoleaks using embolization by micronavigation is an effective and safe method and should be considered as a treatment option for this complication after endovascular repair of abdominal aortic aneurysms.

Resumo

Contexto:O reparo endovascular se estabeleceu como uma modalidade segura e efetiva no tratamento do Aneurisma de Aorta Abdominal. Uma das principais complicações deste tipo de tratamento é o Vazamento ou Endoleak, sendo o do tipo 2 o mais frequente deles.Objetivo:Fazer uma breve revisão de literatura e avaliar a segurança e a efetividade da embolização por micronavegação para o tratamento do Vazamento tipo 2.Método:A revisão dos prontuários dos pacientes submetidos ao Reparo Endovascular do Aneurisma de Aorta abdominal identificou cinco pacientes que apresentavam Endoleak tipo 2 persistente. Esses pacientes foram submetidos à embolização por micronavegação.Resultado:Em todos os casos, houve sucesso angiográfico e as tomografias de controle evidenciavam ausência de Vazamento tipo 2 e diminuição do saco aneurismático, após o procedimento.Conclusão:O tratamento do Endoleak tipo II por embolização por micronavegação é um método efetivo e seguro, sendo considerado uma opção para esta complicação após o Reparo Endovascular do Aneurisma de Aorta Abdominal.
