Deep Vein Thrombosis (DVT) Symptoms and Causes
Deep vein thrombosis (DVT) occurs when a blood clot develops in a vein deep in the body. While these clots most often develop in the lower legs or thighs, they may appear in the upper body, such as the arms or other locations of the body. Deep vein thrombosis (DVT) is a risk for any major surgery, but patients who have surgery of the legs or hips are at higher risk. DVT can pose a serious threat to health. Pieces of a clot can break off and travel through the bloodstream to the lungs. This is called a pulmonary embolism and can be fatal soon after it occurs.
