Abstract : Background: Retroperitoneal open iliac conduits (ROIC) are used in patients with hostile iliac anatomy undergoing endovascular aortic repair (EVAR).

Objectives: We hereby report our experience of ROIC in patients subjected to EVAR.

Methods: This was a retrospective evaluation of 8 patients out of a total of 75 patients (11%) who underwent EVAR in the last 10 years. Pre-procedure computed tomography angiography was used to assess the dimensions of iliac and femoral arteries. Patients who had small arterial dimensions (i.e. smaller than the recommended access size for the aortic endograft device) were subjected to ROIC.

Results: The mean age of the 3 males and 5 females studied was 45.7 ± 15.2 years. The indication for ROIC was the small caliber ilio-femoral access site in 7 patients and atherosclerotic disease in 1 patient. All external grafts were anastomosed to the right common iliac artery except one which was anastomosed to the aortic bifurcation site because of a small common iliac artery. The procedural success rate was 100%. Local access site complications included infection (n=1), retroperitoneal hematoma (n=1), and need for blood transfusion (n=3). The median post-intervention hospital stay was 10 days. All patients had favorable long-term outcomes at a median follow-up of 18 months.

Conclusions: Female patients require ROIC during EVAR more frequently. Adjunctive use of iliac conduit for EVAR was associated with favorable perioperative and short-term outcomes.

Resumo: Contexto: Os condutos ilíacos abertos retroperitoneais são utilizados em pacientes submetidos a reparo endovascular de aneurisma (REVA) com anatomia ilíaca hostil.

Objetivos: Relatamos a nossa experiência com os condutos ilíacos em pacientes submetidos a REVA.

Métodos: Trata-se de uma avaliação retrospectiva de oito pacientes, de um total de 75 (11%), os quais foram submetidos a REVA nos últimos 10 anos. Foi realizada angiotomografia computadorizada antes do procedimento para avaliar as dimensões das artérias ilíaca e femoral. Os pacientes com dimensões arteriais menores, abaixo do tamanho de acesso recomendado para o dispositivo de endoprótese aórtica, foram submetidos a condutos ilíacos.

Resultados: A média de idade dos participantes foi de 45,7±15,2 anos, sendo três do sexo masculino e cinco do sexo feminino. As indicações para condutos ilíacos foram local de acesso ilíaco femoral de pequeno calibre, para sete pacientes, e doença aterosclerótica, para um paciente. Todas as próteses externas foram anastomosadas na artéria ilíaca comum direita, com exceção de uma, que foi anastomosada no local da bifurcação aórtica por apresentar artéria ilíaca comum menor. A taxa de sucesso do procedimento foi de 100%. As complicações no local de acesso incluíram infecção (n = 1), hematoma retroperitoneal (n = 1) e necessidade de transfusão de sangue (n = 3). O tempo mediano de internação hospitalar pós-intervenção foi de 10 dias. Todos os pacientes apresentaram desfechos de longo prazo favoráveis no seguimento mediano de 18 meses.

Conclusões: As pacientes do sexo feminino necessitaram de condutos ilíacos durante REVA com maior frequência. O uso adjuvante de condutos ilíacos com REVA foi associado a desfechos perioperatórios e de curto prazo favoráveis.
