Abstract
A 42-year-old man presented with right leg pain during exercise. Physical examination revealed a diminished pulse. MDCT (multidetector-row computed tomography) demonstrated occlusion of the right popliteal artery due to malposition of the medial head of the gastrocnemius muscle. Popliteal artery entrapment syndrome (Delaney type II) was diagnosed, and a popliteo popliteal bypass was performed using the autogenous great saphenous vein. The postoperative course was without complications, and the ankle-brachial pressure index (ABPI) improved from 0.70 to 1.00. MDCT was useful in characterizing this variation in that it revealed the precise anatomical relation of the muscle, bone, and artery, leading to appropriate treatment.
