Venography
A venogram, also called venography, is a minimally invasive imaging procedure used to evaluate blood flow in the veins, most commonly in the legs and pelvis. During the procedure, contrast dye and X-ray imaging are used to identify narrowed veins, blockages, blood clots, or other conditions affecting venous circulation.
RECOMMENDED
A venogram may be recommended to evaluate:
Leg swelling or pain
Chronic venous insufficiency
Deep vein thrombosis (DVT)
Venous blockages or narrowing
Conditions such as May-Thurner syndrome
Other vein-related circulation problems
WHAT TO EXPECT
During the procedure, a small catheter is inserted into a vein and guided to the area being evaluated. Contrast dye is injected while X-ray images are taken to visualize blood flow and identify any abnormalities within the veins.
The procedure is typically performed using local anesthesia and sedation in an outpatient setting.
POTENTIAL BENEFITS
A venogram can help:
Identify narrowed or blocked veins
Detect blood clots or other venous abnormalities
Evaluate possible causes of leg swelling or pain
Guide treatment planning for venous disease
Support decisions about whether additional vascular procedures may be appropriate
Important Note
Preparation instructions, medication adjustments, and fasting requirements vary based on your medical history and treatment plan. Your care team will provide specific instructions prior to your procedure.
