I found the following info on the web hop it helps: The most common procedures used are (1) electrosurgery – a minor surgical procedure during where a special electrical needle-like instrument is used to remove the angioma, (2) cryotherapy – freezing the affected area with liquid nitrogen, and (3) laser vaporization – using an intense beam of light to remove the angioma. This technique involves minimal harm to surrounding skin tissue. Unless the lesion is particularly large (1/4 inch across or more), you can expect excellent cosmetic results.
