Deep Vein Thrombosis: Blood Clots that can Kill
 |
Deep vein thrombosis (DVT) refers to blood clotting in the vein. According to Thomas Webb, MD, Medical Director of the Alegent Health Heart and Vascular Institute, two million Americans suffer from DVT per year. "150,000 people die each year when pulmonary emboli break off and go to the heart or lungs," says Dr. Webb.

DVT happens when blood flow is restricted and a clot
forms, most commonly in the leg. Causes include poor circulation, a recent heart
attack or stroke, varicose veins, prolonged bed rest and inactivity.
One of the most common symptoms of deep vein thrombosis is unexplained swelling and tenderness in the leg. The condition can be detected by ultrasound, but most patients are unaware that they have the DVT.
Those at highest risk for DVT include individuals who sit a lot, those with cancer, and women who take birth control pills. Situations such as a long airline flight or road trip have been known to result DVT because passengers may fail to move around or stretch as much as they need to. Dr. Webb stresses that travelers should be sure the move their legs around at least every 45 minutes, and while sitting still, do toe raises.
Narrowed or blocked veins due to injury or radiation therapy can also cause DVT. Pregnancy increases the risk of deep vein thrombosis because of the natural tendency for the blood or pregnant women to clot more easily, and certain infections and cancers can make DVT more likely.
