Deep vein thrombosis (DVT) is a condition that occurs when a blood clot forms in a deep vein, usually in the leg. DVT is a serious condition because the blood clot can break loose and travel to the lungs, causing a pulmonary embolism (PE). PE can be life-threatening, as it can block blood flow to the lungs and make it difficult to breathe.
The main cause of DVT is decreased blood flow or stasis, which allows blood to pool and form a clot. Factors that increase the risk of DVT include immobility, such as being confined to a bed for a long period of time or being on a long airplane flight, injury to a vein, certain medical conditions, such as cancer or heart failure, and the use of certain medications, such as hormone replacement therapy or birth control pills. Symptoms of DVT include swelling and pain in the affected leg, warmth over the area, and redness of the skin. Treatment for DVT includes anticoagulant medication, compression stockings, and physical therapy to help improve blood flow.
