Popliteal Artery Entrapment Syndrome
Popliteal artery entrapment syndrome (PAES) refers to symptomatic compression or occlusion of the popliteal artery behind the knee due to adjacent muscles, tendons or fibrous tissues. Symptoms are typically those of intermittent claudication but can also involve swelling and paresthesias. Ultrasound used in conjunction with exercise pressure testing can reveal whether or not there is any compression of the popliteal artery and drop in ankle brachial indices confirming arterial insufficiency.
Testing takes approximately 30 minutes.
