popliteal entrapment syndrome
Also written as: PAES — Popliteal Artery Entrapment Syndrome
A condition where the popliteal artery is compressed by surrounding muscle or fibrous bands, typically affecting young athletes.
Full Definition
Popliteal entrapment syndrome is a rare vascular condition in which the popliteal artery becomes compressed by abnormal positioning of the gastrocnemius muscle, plantaris muscle, or fibrous bands. This compression typically occurs during active plantar flexion or dorsiflexion of the foot. The condition primarily affects young, athletic individuals and can lead to claudication symptoms, arterial thrombosis, or even limb-threatening ischemia if left untreated. Diagnosis often requires dynamic imaging studies such as MRA or CTA with provocative positioning.
Usage
Usage note: Often abbreviated as PAES in clinical documentation. Ensure proper capitalization when spelled out.
