What is the popliteal artery

The popliteal artery is located behind the knee in the popliteal fossa and is a direct extension of the superficial femoral artery after it passes through the adductor hiatus, an opening in the tendinous slip of the great adductor muscle of the thigh.

What is the function of the popliteal artery?

The popliteal artery provides numerous branches of blood supply to the structures of the knee and the lower extremity. Originating from above the knee joint are the superior medial and superior lateral genicular arteries with connections to the deep femoral artery providing collateral blood flow proximal to the knee.

What is popliteal artery injury?

Popliteal artery injury is mainly associated with high energy injury, including knee dislocation and complex tibial plateau fractures or supracondylar femur fractures. 5. Delay in its diagnosis is the leading cause of amputation in this limb-threatening injury.

What muscles does the popliteal artery supply?

The popliteal artery has various muscular branches that provide vascular supply to the hamstring, gastrocnemius, soleus and plantaris muscles. The superior muscular branches of the popliteal artery anastamose with the deep femoral and gluteal arteries of the thigh.

What causes popliteal artery stenosis?

Long-term pressure on the popliteal artery can cause the artery to narrow (stenosis), causing pain and cramping with just slight activity, such as walking. In severe cases or when undiagnosed, the nerves and muscles in the leg can become damaged. Blood clots may occur in the lower leg (deep vein thrombosis).

What does the popliteal vein drain?

The popliteal vein is a deep vein of the leg. It drains blood away from the leg into the femoral vein, which drains blood to the inferior vena cava to return to the right atrium of the heart.

How is Paes diagnosed?

Ankle-brachial index (ABI) measurement is usually the first test done to diagnose PAES . Blood pressure measurements are taken in your arms and legs during and after walking on a treadmill. The ABI is determined by dividing ankle pressure by arm pressure.

How is Paes treated?

Your UPMC vascular surgeon can treat PAES through open surgery to release the compression of the popliteal artery. Most people only spend one to two days in the hospital after surgery and don’t need physical therapy once they return home.

Two possible pedal pulse positions to check Check for either the dorsalis pedis pulse (on the top of the foot) or the posterior tibial pulse (located behind the medial malleolus — the ankle bone).

What is popliteal artery occlusion?

Popliteal artery occlusion is usually the end stage of a long-standing disease process of atheromatous plaque formation. Once formed, the atherosclerotic core is a highly thrombogenic surface that promotes platelet aggregation, which results in disturbances of blood flow.

Why can I feel pulsing in my legs?

Atherosclerosis can cause narrowing of any of the arteries throughout the body. This narrowing or occlusion is called stenosis, and can occur in the arteries in the (the legs), or more infrequently in the arms.

What are the 4 major arteries?

By definition, an artery is a vessel that conducts blood from the heart to the periphery. All arteries carry oxygenated blood–except for the pulmonary artery. The largest artery in the body is the aorta and it is divided into four parts: ascending aorta, aortic arch, thoracic aorta, and abdominal aorta.

Why do knees dislocate easily?

The kneecap rests in a notch at the end of the thigh bone called the trochlear groove. If that notch is very shallow or uneven, it’s easier for the patella to slide out of place. Your ligaments are looser, making your joints more flexible and likely to dislocate.
