Aortic infection accompanied by Leriche syndrome: Presenting with acute mesenteric ischemia and spleen abscesses

Abstract

Aortoiliac occlusive disease, also referred to as Leriche syndrome, is an obstruction of the distal abdominal aorta, iliac and femoropopliteal arteries by cause of atherosclerotic process. The coexistence of aortoiliac occlusive disease and aortic infection has been mentioned in hardly any cases in the literature. Air presence in the aorta is not uncommon in inflammatory and infective conditions. However, aortic air without pseudoaneurysm formation has rarely been reported and is important in the early diagnosis of aortic infections. This report describes a patient with aortic infection accompanied by Leriche syndrome, causing acute mesenteric ischemia and spleen abscesses. We think that this severe disease and its complications can be recognized in even by non-contrast computed tomography in emergency departments.
