Sclerotherapy is a nonsurgical way to treat certain types of vascular malformations. Vascular malformations are abnormal blood vessels or lymphatic channels that develop before a baby is born.
These can causes problems and pain.
Using special equipment, a doctor places a small needle into the vascular malformation and directly injects a medication into the lesion. The medication purposefully causes irritation to close down the abnormal vessels and shrink the malformation. There are several different medications that the doctor may use.
More than one injection may be needed. The procedure takes about an hour. Benefits may not be seen for up to two months.
