![]() If this is negative, then it is unlikely that the patient has a DVT. In some settings, a physician may order a blood test called a D-dimer test. These include CT scans, MRI, and contrast venography. In this test, the veins of the leg can be directly visualized and assessed for the presence of clot. The most commonly used test for DVT is the duplex ultrasound. Diagnosis and tests for Deep Venous Thrombosis These results from obstructed deep veins in the leg causing pressure-related complications. This syndrome includes leg swelling, heaviness, pain and skin changes. Years after a DVT, as many as 20% of patients may develop post-thrombotic syndrome. These symptoms include shortness of breath, chest pain, and palpitations. The first presentation might be of a pulmonary embolism. It is well established that patients with these symptoms may not have a DVT and that patients with a DVT may have few symptoms. The most common symptoms of DVT are calf pain and swelling. What are the symptoms of Deep Venous Thrombosis? Factors and diseases that increase the clotting of blood: cancer, pregnancy, age, history of past DVTs, genetic conditions causing increased clotting, oral contraceptive pill, hormone replacement therapy,.Immobility causing blood to pool and clot in the legs: hospital in-patient, post-surgical patients, prolonged travel (only mild risk factor).Injury to the Deep Veins making them more likely to clot: trauma patients, surgical patients (especially orthopedic surgery and cancer surgery).These categories and the corresponding risk factors include: These can be grouped into one of three categories. The chance of dying from pulmonary embolism is over 25%.Īrm DVTs can occur but are much more rare than leg DVTs. When this happens it is called a pulmonary embolism. If not treated, the blood clots can get larger or break off and go the lungs. When the blood clots in these deep veins, it is called a DVT.ĭVT is a major health concern. In the legs, there are superficial veins (close to the skin) and deep veins (between the muscles). Veins are the 'pipes' that bring blood back to the heart. Deep venous thrombosis (DVT) means formation of a blood clot in the deep veins of the legs.
