Venogram

Why It Is Done

Venography is done to:

• Find blood clots in the deep veins of your leg, arm, or pelvis (deep vein thrombosis, or DVT).
• Find healthy veins to be used in coronary artery bypass graft (CABG) surgery.
• Find the right placement in blood vessels for medical devices such as filters or stents.
• Put a thin flexible tube (catheter) in your kidney (renal) vein to collect a blood sample.
• Check the condition of the valves in the veins of your leg when surgery for varicose veins is being considered.
• Guide the placement of a special intravenous (IV) line that is used for long-term medicine or fluid treatment.
