Deep vein thrombosis (DVT) is a medical condition in which a blood clot (thrombus) forms in a deep vein, typically in the lower leg or thigh. It can also occur in other parts of the body, such as the arm or pelvis. DVT is a serious condition that can be life-threatening if the clot dislodges and travels through the bloodstream to the lungs, causing a pulmonary embolism (PE).
Risk factors for DVT include immobility (such as during long periods of sitting or bed rest), surgery, trauma, pregnancy, hormone therapy, and certain medical conditions such as cancer, heart failure, or a blood clotting disorder. Symptoms of DVT include swelling, pain, warmth, and redness in the affected area.
Treatment for DVT typically involves anticoagulant medication to prevent the clot from growing or traveling, as well as measures to prevent new clots from forming. Compression stockings may also be recommended to improve blood flow and reduce swelling. In some cases, surgery may be necessary to remove the clot. It is important to seek medical attention promptly if you suspect you may have DVT.
