Deep Vein Thrombosis (DVT)

A deep vein thrombosis is a blood clot that forms in one of the deep veins in the body, most commonly in the lower leg. It can block the flow of blood either partially or completely and causes symptoms such as pain and swelling. A major complication of DVT, and the reason why anyone suspecting a DVT should seek immediate medical attention, if that a piece of the blood clot could break off and travel in the bloodstream to the lungs where it could cause a blockage. When the main blood vessel which carries blood from the heart to the lungs becomes blocked this is known as a pulmonary embolism (PE) and is potentially life threatening. The symptoms of PE include chest pain, shortness of breath, coughing and feeling faint. Anticoagulant medicines, such as Warfarin, are normally prescribed for the treatment, and prevention, of DVT and pulmonary embolism.
