Cause

Deep vein thrombosis (DVT) is a blood clot in a deep vein, usually in the legs. Things that lead to a blood clot in a vein include:

• Slowed blood flow, which can happen when you're not active for long periods of time.
• Abnormal clotting problems, which make the blood clot too easily or too quickly.
• Injury to the blood vessels, because blood is more likely to clot in veins shortly after they are injured.
