Phlebography (X-ray of veins)
- Prior appointment: required
- Duration of the investigation: about 10 to 15 minutes
- Preparation: none
- Contrast medium: YES (containing iodine)
Phlebography refers to the depiction of pelvic and leg veins with contrast medium. It is the most reliable method to demonstrate a thrombosis (blood clot) in the deep veins of the leg. It also shows the type and extent of varicose veins, and is therefore an important prerequisite for targeted treatment measures (such as surgery for varicose veins).
Course of the investigation:
A compression bandage is placed on the ankle at the start of the investigation. Contrast medium is then injected into the forefoot through a small plastic tube (Venflon) to fill the leg veins. Contrast medium permits the depiction of vessels from the calf to the pelvis on the X-ray, so that the images can be taken in quick succession. After the investigation the needle is removed and the injection site is covered with a small compression plaster.
