[The trapped popliteal artery syndrome. About one bilateral case (author's transl)]

The authors report on a new case of trapped popliteal artery syndrome. It was bilateral and revealed on one side by acute thrombotic ischemia, leading on this occasion to discovery of the opposite trap. They insist on the extremely easy diagnosis based on a dynamic examination of the limb. The distal pulses must be felt in intermediary position, then after tensing of the gastrocnemia by dorsiflexion of the foot and hyper extension of the knee. Blood velocity measurement by Doppler probes and bifemoralangiography, both dynamic, must precede imperative surgery.
