Deep vein thrombosis is the formation of blood clot in the deep vein usually in the legs. It can develop due to certain conditions that affect the blood clot formation in the body. A blood clot formed in a deep vein can break off and enter the bloodstream. The loose clot formed called embolus can then travel through bloodstream and can reach an artery in the lungs and block blood flow and can cause death. This condition is called pulmonary embolism. Commonly found signs and symptoms of deep vein thrombosis include pain or tenderness, warmth, swelling, redness or discoloration, leg pain and distention of surface veins.
The two tests done to diagnose the deep vein thrombosis are D-dimer blood test and Doppler ultrasound exam of the legs. Treatment includes the medicines that make the blood thin. This will prevent any more formation of blood clots and also will avoid the recent clots to get bigger. The drugs given are heparin and warfarin. Firstly the drug heparin is given and after that warfarin is given after sometime along with heparin. If the medicines do not work in any rare case then surgery is recommended.
