Deep Venous Thrombosis

Excerpt

Deep vein thrombosis (DVT) is an obstructive disease with a hindering venous reflux mechanism. DVT usually involves the lower limb venous system, with clot formation originating in a deep calf vein and propagating proximally. See Image. Deep Vein Thrombosis. It is a common venous thromboembolic (VTE) disorder with an incidence of 1.6 per 1000 annually. The rate of particular site involvement depends on the anatomical location as follows, distal veins 40%, popliteal 16%, femoral 20%, common femoral 20%, and iliac veins 4%.

A deep-vein thrombosis (DVT) is a blood clot that forms within the deep veins, usually of the leg, but can occur in the arms and the mesenteric and cerebral veins. Deep-vein thrombosis is a common and important disease. It is part of the venous thromboembolism disorders, representing the third most common cause of death from cardiovascular disease after heart attacks and stroke. Even in patients who do not get pulmonary emboli, recurrent thrombosis and "post-thrombotic syndrome" are major causes of morbidity. Deep-vein thrombosis is a major medical problem accounting for most cases of pulmonary embolism. Only through early diagnosis and treatment can the morbidity be reduced.
