Abdominal aortic aneurysm with occlusion of three primary mesenteric vessels treated by surgery with perfusion of the left iliac artery

Abstract

A 64-year-old woman who underwent thoraco-abdominal aortic replacement for a Crawford type II aneurysm 11 years ago was referred to our hospital because of a residual juxtarenal abdominal aortic aneurysm. The coeliac, superior mesenteric and inferior mesenteric arteries were occluded. Collateral vessels from the left internal iliac artery to these 3 mesenteric arteries had developed. We performed open aneurysm repair using an extracorporeal circuit to maintain collateral flow to these mesenteric arteries.
