Abstract

Leriche syndrome is characterized by abdominal aorta and/or bilateral iliac occlusive disease, with a triad of clinical symptoms and signs such as claudication, erectile dysfunction, and decreased distal pulses. Diagnostic imaging is one of the key factors for diagnosis of the anatomic origin of the Leriche symptoms. We report the case of a 56-year-old man with diagnosis of abdominal aorta and bilateral iliac occlusive disease with a wide collateral vascular network.

Multidetector computed tomography with coronal volume rendering reconstruction shows abdominal aortic occlusion below renal arteries origin's (white arrowhead) with extension to bilateral common iliac arteries. Note the hypertrophic network of collateral vessels: (1) superior mesenteric artery (yellow arrowhead) communicates with inferior mesenteric artery via Riolan's arc (white arrows), (2) inferior mesenteric artery (green arrowhead) through the superior rectal artery (red arrows) provides blood flow to internal iliac artery (red arrowheads), and (3) inferior epigastric arteries (blue arrowheads) guarantee blood flow to the bilateral external iliac arteries (yellow arrows).
