Which triad is classically associated with Leriche syndrome?

• A. Buttock claudication, erectile dysfunction, absent femoral pulses
• B. Postprandial abdominal pain, weight loss, mesenteric bruit
• C. Intermittent claudication of calves, cold foot, skin ulcers
• D. Hip pain with extension

Answer: (A)

Leriche syndrome is an aortoiliac occlusive disease where blockage of the infrarenal aorta and/or iliac arteries cuts off blood flow to the lower extremities and pelvis. The result is the classic triad: buttock claudication from ischemia of the gluteal muscles, erectile dysfunction from reduced pelvic/perineal perfusion, and absent or very weak femoral pulses due to the occlusion near the iliac bifurcation. This combination reflects the specific vascular territory affected. Other options point to different problems: mesenteric ischemia presents with postprandial abdominal pain, weight loss, and a mesenteric bruit; distal leg disease often causes calf claudication with a cold foot and skin ulcers from tibial/femoral vessel involvement; hip pain with extension isn’t a vascular syndrome.
