Deep Vein Thrombosis

Medically reviewed by Last updated on Apr 2, 2024.

What is a deep vein thrombosis (DVT)?

A DVT is a blood clot that forms in a deep vein of the body. The deep veins in the legs, thighs, and hips are the most common sites for DVT. A DVT can also occur in a deep vein within your arms. The clot prevents the normal flow of blood in the vein. The blood backs up and causes pain and swelling. The DVT can break into smaller pieces and travel to your lungs and cause a blockage called a pulmonary embolism (PE). A PE can become life-threatening.
