Sclerotherapy is a simple procedure that can relieve symptoms due to varicose and leg spider veins in most patients. With this procedure, veins can be dealt with at an early stage, helping to prevent further complications and unsightliness. Patients may need one to several sclerotherapy sessions for any vein region, and the number of injections per session varies.
A tiny needle is used to inject the veins with a medication that painlessly irritates the lining of the vein. Over a short time, in response to the irritation, the vein closes and is reabsorbed. The blood formerly going to the closed vein is then routed to properly working veins, restoring correct circulation.
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 treatment to assist in resolution of the veins.
The procedure, usually performed at Dr. Kabnick’s NYU Vein Center offices, 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.
