Treatment of Congenital Hemangioma
A RICH usually won't need treatment because most shrink on their own. The skin usually looks better if a hemangioma shrinks naturally rather than being treated.

Treatment might be done for either kind of congenital hemangioma (RICH or NICH) if it:

has broken down the skin (ulcerated)
bleeds often
interferes with breathing or vision
makes the heart work too hard pumping blood

Multiple treatments might be used:
ligation: tying off the blood supply to the hemangioma in a surgical procedure

excision: removing the hemangioma with surgery

embolization: using a long, thin tube (catheter) placed in the blood vessel to block the blood flow to the hemangioma
