What is Lower Leg Venography?

Venography is an x-ray test used to study the veins of the body. Lower leg venography is used to study the veins in the legs.

  • Diagnose deep vein thrombosis —a blood clot deep within the leg that may lead to an obstruction of a blood vessel in the lungs ( pulmonary embolism )
  • Find obstructions in the veins
  • Assess vein problems you have had since birth
  • Assess the functioning of deep leg vein valves
  • Find a vein that will be used to make a bypass graft
