sclerotherapy
(SKLAYR-oh-THAYR-uh-pee)
A treatment used to destroy abnormal blood vessels. A liquid is injected into a blood vessel, causing it to scar and break down. The blood flows through nearby healthy veins and the destroyed blood vessel is absorbed into normal tissue. Sclerotherapy is used to treat certain types of vascular tumors. It is also used to treat varicose and spider veins, hemorrhoids, and other blood vessel problems.
