Deep vein thrombosis (DVT) is a type of venous thrombosis involving the formation of a blood clot in a deep vein, most commonly in the legs or pelvis. [9] [a] A minority of DVTs occur in the arms. [11] Symptoms can include pain, swelling, redness, and enlarged veins in the affected area, but some DVTs have no symptoms. [1]
Pratt's sign is an indication of femoral deep vein thrombosis. It is seen as the presence of dilated pretibial veins in the affected leg, which remain dilated on raising the leg. The sign was described by American surgeon Gerald H. Pratt (1928–2006) of St. Vincent's Hospital in 1949. [1] [2]
Other symptoms may include fever and decreased urine output. [2] The risk of death is about 10%. [2] Fat embolism most commonly occurs as a result of fractures of bones such as the femur or pelvis. [3] [1] Other potential causes include pancreatitis, orthopedic surgery, bone marrow transplant, and liposuction.
external rotation of the hip causes pain Peabody's sign: C.N. Peabody: internal medicine: deep vein thrombosis: calf muscle spasm when raising the affected leg with the foot extended Pemberton's sign: Hugh Pemberton: thoracic surgery: retrosternal mass with superior vena cava syndrome
If a blood clot breaks free, goes up to the lung and causes a pulmonary embolism, the most serious complication of DVT, symptoms may include sudden difficulty breathing, chest pain, coughing up ...
Deep vein thrombosis (DVT) is the formation of a blood clot within a deep vein. It most commonly affects leg veins, such as the femoral vein. Three factors are important in the formation of a blood clot within a deep vein—these are: the rate of blood flow, the thickness of the blood and; qualities of the vessel wall.

When physicians find a DVT in the clinical history of their patients, a postthrombotic syndrome is possible if the patients have suggestive symptoms. Ultrasonography for deep venous thrombosis must be performed to evaluate the situation: the degree of obstruction by clots, the location of these clots, and the detection of deep and/or ...
