General Information About the Test
Test Process and Preparation
Doppler ultrasound is the first choice and is highly successful. However, in cases of very deep vein blockages in the groin, abdomen, or pelvis that ultrasound cannot clearly show, or if a surgical intervention / stenting is planned for the patient, Venography is the definitive method to map out the procedure.
The contrast agent is administered by entering a small vein at the distal end of the area to be examined (for example, in the foot) with a fine needle. The progression of the dye through the venous network is watched live on a computer screen, and X-ray films are taken. A slight feeling of warmth may occur while the medication is being administered.
Because a contrast agent (iodine medication) will be used, the patient's kidney function tests are required to be normal. A 4-6 hour fast is generally sufficient before the procedure. After the procedure, plenty of water should be consumed to flush out the medication.
