Venous stents function the same as coronary stents in the manner of improving blood flow. These are metal mesh ducts that expand against constricted or congested vein walls. Their main purpose is to act as a scaffold, allowing veins to be passable and improve blood circulation. Venous stenting is typically done on large, central veins found in the abdomen, chest, and legs.
Some Conditions Treated with Venous Stents
- Post-thrombotic syndrome – people who have this condition suffer from damaged veins with symptoms of pain and swelling.
- May-Thurner syndrome – This forms when the right iliac artery (the artery that runs from the abdomen to the right leg) presses against the left iliac artery, causing it to scar and narrow. This leads to leg pain, swelling, and in some cases, fatigue.
- Chronic Deep Vein Thrombosis (DVT) – This occurs as a blood clot in one of the veins that returns blood from the arm or leg to the heart and lungs.
How To Prepare For The Procedure
Your vascular surgeon will take your medical history and perform a physical exam before the procedure. They may also require the following:
- Venogram – This is a type of x-ray that allows the doctor to have a better look at the anatomy of the patient’s veins. A catheter will be inserted into a vain (usually in the leg), and it will be injected with a contrast dye, allowing the veins to become visible on the image.
- Duplex Ultrasound – This test measures the direction of blood flow and creates images of the patient’s blood vessels. It provides a clear picture of the structure of the blood vessels and helps to identify the exact location of the problem.
Venous stenting is an advanced treatment that helps relieve the pain for people who suffer from blocked arteries. It is a swift process, and you can even go home on the same day.
