When arteries that supply blood to arms and legs experience blockages, those parts of the body are deprived of oxygen and nutrients. If this condition, called Peripheral Arterial Disease, or PAD, is left untreated, it can lead to limb amputation.

Common causes of Peripheral Vascular Disease, or PVD, are PAD, blood clots, and diabetes. With PVD, poor circulation can result in sores and infections, and even amputation in severe cases.

The abdominal aorta is the largest artery in your body, supplying important nutrients and oxygen to internal organs and legs. Sometimes, this key artery can develop a weakness in its wall and begin to bulge. If left unmonitored and untreated, this bulge can enlarge and rupture, causing severe internal bleeding and, possibly, death.

A narrowing of the carotid artery -- the main arteries that supply your brain with blood from your heart -- can increase the risk of stroke.

At East Tennessee Vascular Center, we can also perform minimally-invasive procedures to clear or monitor blocked arteries -- an important measure in determining whether life-saving surgery to prevent stroke is necessary for the patient.

When a blood clot forms in a deep vein in the body (such as an arm or leg vein), it's called a Deep Vein Thrombosis, or DVT. A DVT can increase the chances of stroke.

Patients who experience varicose veins often have aching and tired legs, along with bulging veins just under the surface of the skin.

Phlebitis means "inflammation of a vein," often due to a blockage by a clot. It can be painful and irritating, as well as interrupt blood flow.
