Alternative names: DVT, Deep Venous Thrombosis, Blood Clot In The Legs, Venous Thromboembolism (VTE).
Deep Vein Thrombosis occurs when a blood clot forms in a vein that is deep inside the body, usually in the lower leg or thigh.
DVT is a serious condition because a blood clot (thrombus) that has formed in a vein can break loose and travel to the lungs or another critical organ, potentially causing death.
Blood clots form in the body's deep veins for four main reasons: A damaged inner lining of the vein; slower-than-normal blood flow; thicker-than-normal blood; or blood that is more likely to clot.
The main risk factor for developing Deep Vein Thrombosis is keeping your legs still for long periods of time, for example while in a car or airplane, or during bed rest. This significantly increases the risk a clot forming, so those at risk should get up and walk every 30-60 minutes.
The more risk factors a person has, the greater their chances of developing Deep Vein Thrombosis. Other risk factors include:
Deep vein thrombosis can cause leg pain, but in about half of all cases, deep vein thrombosis occurs without any noticeable symptoms. When symptoms occur, they include:
Signs of a pulmonary embolism include:
Many deep vein thromboses disappear on their own. However, if the clot may travel to the lungs, blocking blood flow and causing a Pulmonary Embolism. A Pulmonary Embolism is potentially fatal.
A doctor should be consulted if signs or symptoms of deep vein thrombosis develop. If signs or symptoms of a pulmonary embolism are present, seek medical attention immediately.
Aspirin has long been known to reduce the risk of heart attack, stroke and deep vein thrombosis by thinning the blood and helping to prevent dangerous clots from forming.
