What is superficial femoral artery occlusion?

What is superficial femoral artery occlusion?

Occlusion of a major lower extremity artery is a primary stimulus to the enlargement of pre-existing collateral vessels, and the superficial femoral artery (SFA) is the most common site of lower extremity arterial occlusions (4).

What is popliteal 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.

What is the superficial femoral artery?

The superficial femoral artery (SFA) is unique in that it runs the length of the thigh without any significant side branches and is subject to a range of forces that alter the flow dynamics, including extension, flexion, contraction, torsion, and compression.

Which type of bypass is used to treat superficial femoral artery occlusion?

Femoral popliteal bypass surgery is used to treat blocked femoral artery.

When does superficial femoral artery become popliteal?

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 is popliteal artery occlusion treated?

Thrombolytic therapy can be used to treat acute and subacute occlusions of the popliteal artery due to underlying stenosis. Thrombolytic therapy is most successful if initiated within 2 weeks after thrombosis (,6).

Can you survive being shot in the femoral artery?

If they’re shot in a vital organ, it only takes a bullet in a bad position for someone to die. So if you’re shot in a major vessel, like the aorta, or the vena cava, or the carotid artery, or the femoral artery, you can just bleed to death from that.

What muscles does the superficial femoral artery supply?

It descends within the vastus medialis muscle to the medial aspect of the knee. Here, it anastomoses with the medial superior genicular artery. Branches of this artery supply the vastus medialis and adductor magnus muscles as well as the proximomedial skin of the thigh.

How long does a femoral bypass last?

In general, a vein bypass in the leg can be expected to last five years or longer in 60 to 70 percent of patients, although about one-quarter to one-third will require additional procedures to maintain the function of these grafts.

What are the symptoms of a blocked femoral artery?

PAD Pain Signs and Symptoms

• Tell-tale signs of femoral artery disease and PAD include:
• Aching, cramping, numbing and weakness that occurs when walking or exercising.
• Coldness in the lower leg or foot, especially when compared with the other leg.
• Sores on your legs, feet or toes that won’t heal.

How do you treat chronic total occlusions in the superficial femoral artery?

Crossing and treating chronic total occlusions (CTOs) in the superficial femoral artery (SFA) remains a significant challenge in the treatment of peripheral artery disease (PAD). When I encounter a CTO in practice, my procedural goal is to cross the lumen in a way that facilitates the use of directional atherectomy.

Can femoral artery occlusions be missed on CT?

Imaging description Superficial femoral artery (SFA) occlusions may be missed in at least two scenarios at cross-sectional imaging. On standard abdominopelvic CT examinations, the SFAs are often only visualized on the last few slices obtained.

How are TASC C and D femoral-popliteal lesions managed?

For suitable patients with TransAtlantic Inter-Society Consensus (TASC) C and D femoral-popliteal lesions involving a flush occlusion of the SFA, we have adopted a technique to manage this disease pattern by combining femoral endarterectomy through a single, small groin incision with distal superficial femoral-popliteal stent-grafting.

Where does the superficial femoral artery give off from the adductor hiatus?

Pao-Yuan Lin, Sandeep J. Sebastin,, Kevin C. Chung, in Operative Techniques: Hand and Wrist Surgery (Second Edition), 2012 The superficial femoral artery gives off the descending genicular artery branch just proximal to the adductor hiatus.
