Venous Disease and Varicose Veins
Venous insufficiency is a very common condition resulting from decreased blood flow from the leg veins up to the heart, with pooling of blood in the veins. Normally, one-way valves in the veins keep blood flowing toward the heart, against the force of gravity. When the valves become weak and don’t close properly, they allow blood to flow backward, a condition called reflux. Veins that have lost their valve effectiveness, become elongated, rope-like, bulged, and thickened. These enlarged, swollen vessels are known as varicose veins and are a direct result of increased pressure from reflux.
Vein Ablation Treatment
This minimally-invasive treatment is an outpatient procedure performed using imaging guidance. After applying local anesthetic to the vein, the interventional radiologist inserts a thin catheter, about the size of a strand of spaghetti, into the vein and guides it up the great saphenous vein in the thigh. Then laser or radiofrequency energy is applied to the inside of the vein. This heats the vein and seals the vein closed.
Reflux within the great saphenous vein leads to pooling in the visible varicose veins below. By closing the great saphenous vein, the twisted and varicosed branch veins, which are close to the skin, shrink and improve in appearance. Once the diseased vein is closed, other healthy veins take over to carry blood from the leg, re-establishing normal flow.
A minimally invasive surgical technique used to treat varicose veins that are not caused by saphenous vein reflux. The abnormal vein is removed through a tiny incision or incisions using a special set of tools. The procedure is done under local anesthesia and typically takes under an hour. Recovery is rapid, and most patients do not need to interrupt regular activity after ambulatory phlebectomy.
Can also be used to treat some varicose and nearly all spider veins. An extremely fine needle is used to inject the vein with a solution that shrinks the vein.
Involves an interventional radiologist passing a thin tube called a catheter into the vein using ultrasound guidance and injecting a substance that causes the veins to scar and close – rerouting the blood to healthier veins. The affected vein forms a knot of scar tissue that is absorbed by the body over time.
