Popliteal artery compression syndrome

from Wikipedia, the free encyclopedia

The artery-popliteal compression syndrome ( English popliteal artery entrapment syndrome (PAES) ), is a circulatory disorder of the lower leg , on damage to the popliteal artery ( popliteal artery is based).

The reason for this are variations in the course of the muscle attachments or the vessels. When exposed to stress, the popliteal artery is squeezed (compression) and the arterial wall is damaged, which in turn can lead to thrombosis and further vascular narrowing and even to vascular occlusion. Signs of a circulatory disorder appear in the lower leg, as in arterial occlusive disease .

The symptoms include pain in the lower leg when exerted, as well as coldness and pallor in the lower leg.

The disease occurs mainly in younger patients and often occurs on both sides. It is difficult to see when the patient is at rest, as the pulse in the ankle arteries may be normal. A duplex sonography or magnetic resonance tomography of the hollow of the knee with load (flexion and extension of the foot in the ankle joint against resistance) is required for diagnosis .

Clinical test: When the foot of the affected leg is plantar flexed, the cw Doppler signal of the posterior tibial artery disappears (but also positive in 50% of the "healthy" people). Confirmation of diagnosis: digital subtraction angiography under provocation.

Therapy takes place through surgery.
