Leriche syndrome is caused by aortoiliac occlusive disease. The classic clinical triad consists of:

• A Claudication of buttocks/thighs, impotence, absent femoral pulses ✓
• B Rest pain, gangrene, and absent popliteal pulses
• C Bilateral calf claudication, dependent rubor, and absent ankle pulses
• D Thigh claudication, hypertension, and absent radial pulse

Explanation

Leriche syndrome results from chronic occlusion of the aortic bifurcation. The classic triad is: bilateral gluteal/thigh claudication, erectile dysfunction (due to lack of flow in internal iliac arteries), and absent or diminished femoral pulses. It is more common in men and typically presents insidiously. Revascularisation by aortobifemoral bypass or aortoiliac endarterectomy is the definitive treatment.
