Definition of Venogram – Diagnostic Procedure

Venogram is a diagnostic procedure to evaluate the flow of blood in the veins, usually in the legs. The cardiologist may use this procedure to diagnose varicose veins, venous insufficiency, or deep vein thrombosis (dvt).

For venogram, the radiologist injects a small amount of contrast dye into the affected vein network and then takes X-rays or fluoroscopy images as the dye moves with the blood through the veins. The venogram shows any structural abnormalities and occlusions – requires no preparation or recovery.

Some people experience a minor burning sensation with injection of the contrast dye. People who are allergic to iodine may have an allergic reaction to the dye.
