Spider angiomas are asymptomatic and some resolve spontaneously. This is common in the case of children, although they may take several years to disappear. If the spider angiomas are associated with pregnancy, they may resolve after childbirth. In women taking oral contraceptives, they may resolve after stopping these contraceptives. The spider angiomas associated with liver disease may resolve when liver function increases or when a liver transplant is performed.
For spider angiomas on the face, techniques such as electrocautery and laser treatment with Intracel or Pulse dye laser can be used to remove the lesion. There is a minor risk of a scar, although the results are generally good. Spider angiomas may reappear after the treatment.
If the centre of the angioma is pricked with a hypodermic needle, opening the dilated arteriole, blood will flow freely for some time unless pressure is applied; the arteriole will then shrink or coagulate and the angioma will disappear. This treatment is minimally painful and leaves no scar.
