Question

Claudication due to popliteal femoral incompetence is primarily seen in

• A. Thigh
• B. Calf
• C. Buttocks
• D. Feet

Answer 1

The Correct Option is B

Level-localisation angle. Intermittent claudication is reproducible muscle pain on walking that eases with rest, and its location reliably points one level below the diseased artery. Build a top-to-bottom map: aorta and common iliac block gives buttock and thigh pain (the Leriche triad adds impotence and absent femoral pulses), the femoral segment gives thigh symptoms, the superficial femoral and popliteal segment gives calf pain, and tibial or pedal disease gives foot symptoms. Femoropopliteal disease is in fact the commonest location of atherosclerotic peripheral arterial disease, so calf claudication is the textbook presentation. Applying the map to popliteal-femoral incompetence lands squarely on the calf. Reference: BDC, 7e, Vol 2, p 137.
