Popliteal artery entrapment syndrome

Popliteal artery entrapment syndrome (PAES) is a rare condition that affects the blood vessels and muscles in the popliteal fossa, the area behind the knee. It can cause pain, numbness, and even tissue damage due to reduced blood flow.

Causes[edit | edit source]

PAES is caused by an abnormal positioning of the popliteal artery, the main artery that runs through the popliteal fossa. This can be due to a congenital defect, where the artery is in an abnormal position from birth, or it can be acquired, often as a result of increased muscle mass in the calf.

Symptoms[edit | edit source]

The symptoms of PAES can vary depending on the severity of the condition. They can include:

Pain in the calf or foot, often after exercise
Numbness or tingling in the foot
Coldness in the foot
Pale or bluish skin color
Weak or absent pulse in the foot

Diagnosis[edit | edit source]

PAES can be difficult to diagnose because its symptoms are similar to those of other conditions. However, a number of tests can be used to confirm a diagnosis, including:

Treatment[edit | edit source]

Treatment for PAES depends on the severity of the condition. In mild cases, conservative treatments such as rest, physical therapy, and medication may be sufficient. In more severe cases, surgery may be necessary to reposition the artery and relieve the entrapment.
