Deep Vein Thrombosis
Overview
A deep-vein thrombosis (DVT) is a blood clot that originates in the deep veins of the body, primarily in the legs, but also in the arms, mesenteric, and cerebral veins. Deep-vein thrombosis (DVT) is a common and serious condition. It's a symptom of venous thromboembolism, which is the third leading cause of death from cardiovascular illness after heart attacks and stroke. Recurrent thrombosis and "post-thrombotic syndrome" are a major cause of morbidity in people who do not develop pulmonary emboli.
