Deep Vein Thrombosis Causes and Risks

Deep vein thrombosis (DVT) occurs when a blood clot forms in a vein deep inside a muscle in your body. It usually happens in legs, but can also develop in your arms, chest, or other areas of your body. And though DVT is not common, it can be dangerous. The blood clot can block your circulation or lodge in a blood vessel in your lungs, heart, or other area. The clot can cause severe organ damage and even death -- within hours.

Slowed blood flow

Blood does not flow normally if you are not active for long periods of time. Examples include:

  • Long-term bed rest, such as after a surgery, injury, or serious illness.
  • Sitting for a long time, especially when traveling long distances.
  • Leg paralysis.

Abnormal clotting

Some people have blood that clots too easily or too quickly. Problems that may cause increased clotting include:

Injury to the blood vessel wall

Blood is more likely to clot in veins shortly after they are injured. Examples include:

  • Recent surgery that involved the legs, hips, belly, or brain.
  • Having a central venous catheter during a hospital stay.
  • Injury, such as a broken hip.
