Sclerotherapy is an injection treatment used to eliminate spider veins and small to medium sized varicose veins. A mild chemical solution is injected into the problem vein with a very fine needle. This solution causes the vein wall to become irritated and ultimately collapse. A small dressing and your compression stockings are then applied helping to seal the vein wall together. Over time, your body will reabsorb the collapsed vein and re-route blood through the healthy veins.
No pre-treatment preparation is needed. Most patients are asked to avoid prolonged sitting and standing for three days. Walking is encouraged after the treatments and prescription strength compression stockings are worn for several weeks following treatment. A single sclerotherapy session of 20 minutes usually involves multiple injections.
The number of sclerotherapy sessions varies depending on the number of veins to be treated, healing time needed, and desired result.
Ultrasound guided sclerotherapy uses the ultrasound to locate diseased veins not detectable by direct visualization or with the vein light. The ultrasound then helps guide the placement of the needle for the injection.
