How to manage a case of aymptomatic thoraco-abdominal aortic aneurysm with occluded mesenteric arteries

Abstract

We report a unique case of a 57-year-old male having a suprarenal thoraco-abdominal aortic aneurysm which is extending till the origin of superior mesenteric artery (SMA). The origins of celiac artery and SMA were totally occluded and filled retrogradely through dense collateral vessels arising from the inferior mesenteric artery. Surprisingly, the patient was not having any symptoms related to mesenteric ischemia. We decided to use a conventional aortic aneurysm stent graft to repair it without revascularizing the occluded mesenteric arteries. After 1 month, CT aortogram was repeated which revealed a well-apposed stent graft with no endoleaks. He did not have any clinical signs and symptoms attributable to mesenteric ischemia.
