A 55-year-old man presents with bilateral lower limb claudication and erectile dysfunction. On examination, femoral pulses are reduced bilaterally and popliteal pulses are absent. Aortobifemoral bypass is planned. The symptom triad of bilateral buttock/thigh claudication, absent femoral pulses, and erectile dysfunction is called:

• A May–Thurner syndrome
• B Takayasu arteritis with aortic involvement
• C Blue toe syndrome from aortic atheroembolism
• D Leriche syndrome ✓

Explanation

Leriche syndrome describes the triad of bilateral buttock/hip/thigh claudication, absent or diminished femoral pulses, and erectile dysfunction, resulting from chronic occlusion or severe stenosis of the aortic bifurcation. It is caused by atherosclerotic disease of the infrarenal aorta and common iliac arteries. Management is aortobifemoral bypass (gold standard) or endovascular aortobiiliac stenting in high-risk patients.
