Blood Clots in the Upper and Lower Leg Veins

The deep veins of the leg have different terms to describe their location:

  • Upper (proximal) leg veins are those above the knee but below the waist.
    • Popliteal veins are located behind the knee.
    • Iliac and femoral veins are in the groin area.
  • Lower (distal) leg veins are those below the knee.
    • Distal leg veins are located in the calf and ankle.

A person with a blood clot in a deep upper (proximal) leg vein is at increased risk for a blood clot in the lung (pulmonary embolism) or other complications.

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.
