From Foot Trauma to Leriche Syndrome: A Case of an Ulcerated Lesion Leading to a Vascular Diagnosis

Leriche syndrome, or aortoiliac occlusive disease, is a rare but serious condition caused by occlusion of the distal aorta and/or iliac arteries. It classically presents with claudication, diminished pulses, and, in severe cases, critical limb ischemia. We report the case of a 35-year-old man, a chronic smoker, who presented with an ulcerated and secondarily infected lesion on the foot following trauma occurring 4 months prior. Clinical examination revealed absence of bilateral femoral and popliteal pulses, leg cramps, weakness, and paresthesias. Imaging confirmed extensive aortoiliac occlusion, with findings consistent with Leriche syndrome. The patient underwent revascularization, which resulted in significant clinical improvement. This case highlights the importance of early recognition and prompt intervention in young patients with atypical ischemic symptoms.
