What is the SFA artery
By Olivia Bennett
The superficial femoral artery (SFA) is a frequent target of atherosclerotic disease predominantly in the proximal section near the bifurcation to the deep femoral artery and in the distal section where the adductor muscles tend to compress the artery.
What is the SFA vessel?
The superficial femoral artery (SFA), as the longest artery with the fewest side branches, is subjected to external mechanical stresses, including flexion, compression, and torsion, which significantly affect clinical outcomes and the patency results of this region after endovascular revascularization.
Is SFA a coronary artery?

What is SFA 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 SFA in cardiology?
INTRODUCTION. Chronic total occlusion (CTO) of the superficial femoral artery (SFA) is a commonly encountered target lesion in patients with symptomatic lower extremity arterial disease. 1) Endovascular treatment of SFA CTO is often challenging because of the lesion length and presence of calcification.
What is a SFA angioplasty?
Abstract. Introduction: Peripheral arterial disease (PAD) of the superficial femoral artery (SFA) is the most common cause of intermittent claudication. Several endovascular treatment options exist; the most frequent are angioplasty or angioplasty with stent placement.
What is the SFA in medical terms?
SFA – superficial femoral artery.
What causes claudication?
Claudication is pain in the legs or arms that comes on with walking or using the arms. This is caused by too little blood flow to your legs or arms. Claudication is usually a symptom of peripheral artery disease, in which the arteries that supply blood to your limbs are narrowed, usually because of atherosclerosis.What are the symptoms of a blocked femoral artery?
- 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.
- Buttock pain.
- Numbness, tingling, or weakness in the legs.
- Burning or aching pain in the feet or toes while resting.
- A sore on a leg or a foot that will not heal.
- One or both legs or feet feeling cold or changing color (pale, bluish, dark reddish)
- Loss of hair on the legs.
- Impotence.
Where is SFA?
U.S. Stephen F. Austin State University (SFA) is a public university in Nacogdoches, Texas, United States.
Where is the distal SFA?
The distal SFA is punctured at the proximal part of the adductor canal with a 21-gauge micropuncture needle under a roadmap fluoroscopic guidance, and an angiogram is performed through a 3 Fr dilator to confirm that the access to the SFA is achieved properly (A). Then, a 5 Fr sheath is inserted into the distal SFA (B).
What arteries are in the leg?
The femoral artery is the major blood vessel supplying blood to your legs. It’s in your upper thigh, right near your groin.
Which artery is most prone to occlusion in the lower extremities?
Many of these are related to popliteal artery disease. Popliteal artery occlusion and the disease processes leading up to it cause morbidity and mortality by decreasing or completely blocking blood supply through the popliteal artery and into the lower leg and foot.
Is the femoral artery considered a peripheral artery?
Lower extremity PAD affects the arteries that supply blood to the muscles in the legs. Three of the arteries most commonly blocked are the iliac artery, the superficial femoral artery (known as SFA), and the infrapopliteal arteries that are below the knee.
Is the femoral artery in both legs?
Put simply, the femoral artery originates in the groin and runs down each leg, stopping right around the knee. (At the knee, the femoral artery becomes the popliteal artery).
What does SFA mean in Canada?
The Service Fees Act (SFA) is legislation that increases transparency, accountability and predictability for service fees that the Government of Canada charges to Canadians.
When does femoral artery become popliteal?
The popliteal artery is the continuation of the femoral artery that begins at the level of the adductor hiatus in the adductor magnus muscle of the thigh. As it continues down, it runs across the popliteal fossa, posterior to the knee joint.
What is the meaning of SFA test?
The seminal fluid analysis (SFA) includes determination of ejaculate volume, semen color, pH, viscosity, and liquefaction along with sperm count, sperm motility, and sperm speed. In addition to SFA, a morphology, post-ejaculate urine, and seminal fructose test may be done. See explanation below.
What does PTCA mean in medical terms?
PTCA, or percutaneous transluminal coronary angioplasty, is a minimally invasive procedure that opens blocked coronary arteries to improve blood flow to the heart muscle. First, a local anesthesia numbs the groin area. Then, the doctor puts a needle into the femoral artery, the artery that runs down the leg.
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.
What are the disadvantages of stents?
- Re-narrowing of your artery. When angioplasty is combined with drug-eluting stent placement, there’s a small risk the treated artery will become clogged again. …
- Blood clots. Blood clots can form within stents even after the procedure. …
- Bleeding. You may have bleeding in your leg or arm where a catheter was inserted.
Can you stent a 100% blocked artery?
“Patients typically develop symptoms when an artery becomes narrowed by a blockage of 70 percent or more,” says Menees. “Most times, these can be treated relatively easily with stents. However, with a CTO, the artery is 100 percent blocked and so placing a stent can be quite challenging.”
What dissolves artery plaque?
HDL is like a vacuum cleaner for cholesterol in the body. When it’s at healthy levels in your blood, it removes extra cholesterol and plaque buildup in your arteries and then sends it to your liver. Your liver expels it from your body. Ultimately, this helps reduce your risk of heart disease, heart attack, and stroke.
How serious is a femoral artery blockage?
The arteries in your legs and feet can get blocked, just like the arteries in your heart. When this happens, less blood flows to your legs. This is called peripheral artery disease (PAD). Occasionally, if your leg arteries are badly blocked, you may develop foot pain while resting or a sore that won’t heal.
What is claudication pain like?
Typical symptoms of claudication include: Pain, a burning feeling, or a tired feeling in the legs and buttocks when you walk. Shiny, hairless, blotchy foot skin that may get sores. The leg is pale when raised (elevated) and red when lowered.
Can claudication go away?
Claudication is muscular pain, cramping, or fatigue that typically occurs during exercise and goes away with rest. Claudication is primarily a symptom of conditions that reduce blood flow in the legs, especially peripheral artery disease (PAD).
What type of doctor treats claudication?
Primary care doctors, such as internists and family doctors, may treat people who have mild PAD. For more advanced PAD, a vascular specialist may become involved. This is a doctor who specializes in treating blood vessel diseases and conditions. A cardiologist may also be involved in treating people who have PAD.
What kind of doctor treats poor circulation in legs?
A vascular physician will diagnose any conditions, prescribe any medications you might need, and formulate an actionable treatment plan for managing your poor circulation. You may require medication or procedures to treat your conditions, but your doctor will also recommend lifestyle changes.
How do you clear clogged arteries without surgery?
Through angioplasty, our cardiologists are able to treat patients with blocked or clogged coronary arteries quickly without surgery. During the procedure, a cardiologist threads a balloon-tipped catheter to the site of the narrowed or blocked artery and then inflates the balloon to open the vessel.
Is vascular disease curable?
If peripheral vascular disease goes untreated, there is a chance that it may progress into critical limb ischemia, a severe stage of PVD that can result in the loss of an affected limb. But if caught in its early stages, peripheral vascular disease is a treatable and reversible disease.
