Deep venous thrombosis
Deep venous thrombosis is a blood clot that forms in a vein deep inside a part of the body. It mainly affects the large veins in the lower leg and thigh. Causes

A pacemaker catheter that has been passed through the vein in the groin •
Family history of blood clots
Fractures in the pelvis or legs
Giving birth within the last 6 months
Recent surgery (most commonly hip, knee, or female pelvic surgery) •

Newer forms of heparin can be given by injection once or twice a day. You may not need to stay in the hospital as long, or at all, if you are prescribed this newer form of heparin. Warfarin (Coumadin) is usually started along with heparin.
