Femoral Artery: From 2 Different Sources


A major blood vessel that supplies oxygenated blood to the leg. The femoral artery is formed in the pelvis from the iliac artery (the terminal branch of the aorta). It then runs from the groin, down in front of the thigh, and passes behind the knee to become the popliteal artery, which branches again to supply the lower leg.

Adjective relating to the FEMUR or the region of the thigh. For example, the femoral nerve, artery, vein and canal.... femoral

Radial Artery

This artery arises from the brachial artery at the level of the neck of the radius. It passes down the forearm to the wrist, where it is easily palpated laterally. It then winds around the wrist to the palm of the hand to supply the ?ngers. (See ARTERIES.)... radial artery

Temporal Artery

A branch of the external carotid artery that is the main vessel supplying blood to the temple and scalp.... temporal artery

Artery

A blood vessel that carries blood away from the heart. Systemic arteries carry blood pumped from the left ventricle of the heart to all parts of the body except the lungs. The largest systemic artery is the aorta, which emerges from the left ventricle; other major systemic arteries branch off from the aorta. The pulmonary arteries carry blood from the right ventricle to the lungs.

Arteries are tubes with thick, elastic, muscular walls able to withstand the high pressure of blood flow. The structure of arteries helps to even out the peaks and troughs of blood pressure caused by the heartbeat, so that the blood is kept flowing at a relatively constant pressure. (See also arteries, disorders of.)... artery

Brachial Artery

The artery that runs down the inner side of the upper arm, between the armpit and the elbow.... brachial artery

Carotid Artery

Any of the main arteries of the neck and head. There are 2 common carotid arteries (left and right), each of which divides into 2 main branches (internal and external).

The left carotid arises from the aorta and runs up the neck on the left side of the trachea (windpipe). The right carotid arises from the subclavian artery (which branches off the aorta) and follows a similar route on the right side of the

neck. Just above the level of the larynx (voice-box), each carotid artery divides to form an external carotid artery and an internal carotid artery. The external arteries have multiple branches that supply most tissues in the face, scalp, mouth, and jaws; the internal arteries enter the skull to supply the brain and eyes. At the base of the brain, branches of the 2 internal carotids and the basilar artery join to form a ring of vessels called the circle of Willis. Narrowing of these vessels may be associated with transient ischaemic attack (TIA); obstruction of them causes a stroke. carpal tunnel syndrome Numbness, tingling, and pain in the thumb, index finger, and middle fingers caused by compression of the median nerve at the wrist. Symptoms may be worse at night. The condition results from pressure on the nerve where it passes into the hand via a gap (the “carpal tunnel’’) under a ligament at the front of the wrist. It is common among keyboard users. It also occurs without obvious cause in middleaged women, and is associated with pregnancy, initial use of oral contraceptives, premenstrual syndrome, rheumatoid arthritis, myxoedema, and acromegaly.

The condition often disappears without treatment.

Persistent symptoms may be treated with a corticosteroid drug injected under the ligament, or the ligament may be cut to relieve pressure on the nerve.... carotid artery

Femoral Nerve

One of the main nerves of the leg. The nerve fibres making up the femoral nerve emerge from the lower spine and run down into the thigh, where they branch to supply the skin and quadriceps muscles.

Damage to the femoral nerve (which impairs the ability to straighten the knee) is usually caused by a slipped disc in the lumbar region of the spine (see disc prolapse). Damage may also result from a backward dislocation of the hip or a neuropathy.... femoral nerve

Coronary Artery Disease

Narrowing of the coronary arteries, which supply blood to the heart, leading to damage or malfunction of the heart. The most common heart disorders due to coronary artery disease are angina pectoris and myocardial infarction (heart attack). The usual cause of narrowing of the arteries is atherosclerosis, in which fatty plaques develop on the artery linings. The vessel can become totally blocked if a blood clot forms or lodges in the narrowed area. Atherosclerosis has many interrelated causes including smoking, a high-fat diet, lack of exercise, being overweight, and raised blood cholesterol levels. Other factors include a genetic predisposition and diseases such as diabetes mellitus and hypertension.

The first symptom of coronary artery disease is frequently the chest pain of angina. Treatment is with drugs such as glyceryl trinitrate and other nitrate drugs, beta-blockers, calcium channel blockers, potassium channel activators, and vasodilator drugs. If drug treatment fails to relieve the symptoms, or there is extensive narrowing of the coronary

arteries, blood flow may be improved by balloon angioplasty or coronary artery bypass surgery.... coronary artery disease

Retinal Artery Occlusion

Blockage of an artery supplying blood to the retina, most commonly due to thrombosis or embolism, The disorder can result in permanent blindness or loss of part of the field of vision, depending on the artery affected and whether or not the condition can be treated quickly enough.... retinal artery occlusion

Coronary Artery Vein Bypass Grafting (cavbg)

When coronary arteries, narrowed by disease, cannot supply the heart muscle with su?cient blood, the cardiac circulation may be improved by grafting a section of vein from the leg to bypass the obstruction. Around 10,000 people in the United Kingdom have this operation annually and the results are usually good. It is a major procedure that lasts several hours and requires the heart to be stopped temporarily, with blood circulation and oxygenation taken over by a HEART-LUNG MACHINE.... coronary artery vein bypass grafting (cavbg)

Intracoronary Artery Stenting

A narrowed or blocked coronary artery (see ARTERIES) can compromise the blood supply to the heart muscle (see HEART, DISEASES OF). A supportive tube or stent passed into each affected artery can restore the blood supply. The stent has a HEPARIN coating to stop blood clots from forming. Since it was ?rst performed in 1987, intracoronary stents have cut the reblockage rate from one in three patients who have had coronary ANGIOPLASTY to fewer than one in ten in cases where a stent was used with angioplasty.... intracoronary artery stenting

Coronary Artery

Either of the 2 main arteries that supply the tissues of the heart with oxygen-rich blood. These are

known as the left and right main coronary arteries and arise directly from the aorta. The term coronary artery is also applied to any of the arteries that branch off from the main coronary arteries, such as the left circumflex artery and the left anterior descending artery. Blockage of a coronary artery as a result of atherosclerosis can lead to myocardial infarction.

Coronary Artery Bypass

A major heart operation to bypass narrowed or blocked coronary arteries using additional blood vessels (such as a mammary artery) to improve blood flow to the heart muscle. This operation is used when symptoms of coronary artery disease have not been relieved by drugs or balloon angioplasty.

Before surgery, sites of blockage in the arteries are identified using angiography. In some cases, minimally invasive surgery can be used, avoiding the need to stop the heart and use a heart–lung machine during the operation. The long term outlook after a bypass is good, but the grafted vessels may also eventually become blocked by atherosclerosis.... coronary artery bypass

Femoral Hernia

A type of hernia that occurs in the groin area, where the femoral artery and femoral vein pass from the lower abdomen to the thigh.... femoral hernia

Femoral Epiphysis, Slipped

Displacement of the upper epiphysis (growing end) of the femur (thigh bone). Such displacement is rare; it usually affects children between 11 and 13, and occurs more often in boys and obese children. The condition may also run in families. During normal growth, the epiphysis is separated from the shaft of the bone by a plate of cartilage. This is an area of relative weakness, so that a fall or other injury can cause the epiphysis to slip out of position. A limp develops, and pain is felt in the knee or groin. The leg tends to turn outwards and hip movements are restricted.

Surgery is needed to fix the epiphysis into its correct position and is usually completely successful.

In some cases, the other hip may also need to be stabilized.... femoral epiphysis, slipped

Slipped Femoral Epiphysis

See femoral epiphysis, slipped.... slipped femoral epiphysis

Basilar Artery

an artery in the base of the brain, formed by the union of the two vertebral arteries. It extends from the lower to the upper border of the pons Varolii and then divides to form the two posterior cerebral arteries.... basilar artery

Brachiocephalic Artery

see innominate artery.... brachiocephalic artery

Carotid Artery Stenosis

(carotid stenosis) narrowing of the carotid artery, which reduces the supply of blood to the brain and is a cause of strokes. It is treated by surgical excision or bypass of the narrowed segment (see also endarterectomy) or by inserting a *stent into the carotid artery.... carotid artery stenosis

Coronary Artery Bypass Graft

(CABG) *coronary revascularization in which a segment of a coronary artery narrowed by atheroma is bypassed by an *autologous section of healthy saphenous vein or internal mammary artery at *thoracotomy.

Pulmonary Artery

the artery that conveys blood from the heart to the lungs for oxygenation: the only artery in the body containing deoxygenated blood. It leaves the right ventricle and passes upwards for 5 cm before dividing into two, one branch going to each lung. Within the lungs each pulmonary artery divides into many fine branches, which end in capillaries in the alveolar walls. See also pulmonary circulation.... pulmonary artery
