Venous Thrombosis

Venous thrombosis is a condition in which a blood clot forms in a vein. Typically it affects veins deep in the leg, arm, or groin. Sometimes this clot is called a deep vein thrombosis or DVT blood clot. The clot reduces blood flow through the vein. 

Venous thrombosis is an acute condition. That means that it is fairly sudden and severe. There is also the risk that the clot will move to another area such as the lungs.


Symptoms of venous thrombosis include:

  • Pain or stiffness in the extremities, most commonly the feet and ankles
  • Swelling in the extremities
  • Redness in the affected area

Risk Factors

You’re more likely to develop a venous blood clot if:

  • You have weak valves in the vein (called valvular incompetence).
  • You have an injury that affects the vein.
  • You have recently had surgery.
  • You have a sedentary (non-active) lifestyle.


We diagnose venous thrombosis using painless, non-invasive assessments including ultrasound and a physical exam.


We treat venous thrombosis with a nonsurgical procedure called a venous thrombectomy .
