Sclerotherapy (injections) can be used to treat both varicose veins and spider veins.

The procedure is simple. A tiny needle is used to inject the veins with a medication that irritates the lining of the vein. Over a short time, in response to the irritation, the vein closes and is reabsorbed. The blood from the closed vein is routed to properly working veins, restoring correct circulation.

Sclerotherapy relieves symptoms due to varicose and spider veins in most patients. With this procedure, veins can be dealt with at an early stage, helping to prevent further complications and unsightliness.

You may need one to several sclerotherapy sessions for any vein region and the number of injections varies per session. Generally, normal activities can be resumed after sclerotherapy. Medically prescribed support hose and/or bandages may be needed for one day to several weeks after a session to assist in resolution of the veins.

The procedure, usually performed at the NYU Vein Center, causes minimal or no discomfort. Bruising and pigmentation may occur after the sclerotherapy. If bruising occurs, it usually disappears within one to two weeks. Although pigmentation almost always fades, it can last for several months. Scarring and other complications are rare.
