popliteal entrapment syndrome
Pronunciation: pop-LIT-ee-al en-TRAP-ment SIN-drome
Congenital condition where the popliteal artery is compressed by surrounding muscle or fibrous bands. Requires specialized imaging protocols to demonstrate dynamic compression during plantarflexion.
Full Definition
Popliteal entrapment syndrome is a rare congenital vascular disorder characterized by compression of the popliteal artery by aberrant muscle bellies or fibrous bands in the popliteal fossa. The condition primarily affects young athletes and requires dynamic imaging studies, often with provocative maneuvers such as active plantarflexion or passive dorsiflexion, to demonstrate arterial compression. CT or MR angiography with stress positioning is the preferred imaging modality. Early diagnosis is crucial as chronic compression can lead to arterial stenosis, thrombosis, or aneurysm formation.
Usage
Usage note: Often abbreviated as PAES in clinical documentation. Requires hyphenation when used as compound modifier.
