What causes popliteal artery entrapment syndrome?
What causes popliteal artery entrapment syndrome?
Popliteal artery entrapment syndrome (PAES) is caused by an abnormal calf muscle, usually the gastrocnemius muscle. The condition may occur from birth (congenital) or develop later in life (acquired).
Where does the popliteal artery start and end?
The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle. It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries.
What are the genicular branches of the popliteal artery?
The five branches are:
- Superior lateral genicular artery.
- Superior medial genicular artery.
- Middle genicular artery.
- Inferior lateral genicular artery.
- Inferior medial genicular artery.
Where is the femoral popliteal artery?
The popliteal artery is the direct continuation of the superficial femoral artery, at the point where it exits the adductor canal at the adductor hiatus, and passes into the popliteal fossa as the vessel courses posteriorly behind the knee.
How do you fix popliteal artery entrapment?
Surgery is the only way to correct the abnormal calf muscle and free the trapped artery. Your doctor will likely recommend surgery if your symptoms significantly affect your everyday or athletic activities.
What nerve runs with the popliteal artery?
The Popliteal vein: It is superficial to the and travels with the Popliteal artery. The Tibia nerve and common Fibular nerve: These are the two major branches of the Sciatic nerve.

What happens when the femoral artery is blocked?
Long-term narrowing or total blockage of the femoral artery can cause claudication, fatigue and painful cramping in the calf muscles when walking. In extreme situations, a blocked artery in your leg can lead to amputation (removal) of your toes, foot or leg.
How do you test for popliteal entrapment?
Magnetic resonance angiography (MRA) shows the calf muscle that is trapping the artery. It can also reveal how much of the popliteal artery is narrowed. You may be asked to flex your foot or press it against a board during this test. Doing so helps your doctor determine how blood is flowing to your lower leg.
