Venous thromboembolism (VTE) is a condition that involves the formation of blood clots in the veins, typically in the deep veins of the legs or pelvis. These blood clots can break loose and travel through the bloodstream, potentially causing a blockage in the lungs (pulmonary embolism) or other parts of the body. VTE is a serious and potentially life-threatening condition that requires prompt medical attention and treatment. Risk factors for VTE include immobility, surgery, cancer, obesity, and certain genetic factors. Treatment for VTE often includes blood thinning medications, compression stockings, and lifestyle modifications to reduce the risk of future blood clots.
