popliteal entrapment syndrome
Compression of the popliteal artery by surrounding muscle or fibrous bands, typically affecting young athletes.
Full Definition
Popliteal entrapment syndrome is a rare condition where the popliteal artery becomes compressed by abnormal muscle belly positioning or fibrous bands in the popliteal fossa. The syndrome primarily affects young, athletic individuals and is classified into six types based on anatomical variations. Symptoms include exercise-induced claudication, foot coolness, or acute limb ischemia. The medial head of the gastrocnemius muscle is most commonly involved in the entrapment mechanism. Early recognition and surgical intervention are important to prevent permanent arterial damage.
