Spider Naevi


Spider Naevi

Spider Naevi are a common skin lesion that can be easily removed with our 532 laser.

In most instances the spider naevi can be removed in a single session with a few ”blasts” of the laser. Spider naevus can occur at any age and most children can be treated but NOT ALL skin types.

The treatment is very safe and down time is minimal. It is much less traumatic and less painful than removal by electrolysis and laser treatment of spider naevi is more successful with a high cure rate and high degree of patient satisfaction. Laser removal of spider naevi is less likely to cause scarring than removal with electrolysis.

Spider naevi are usually asymptomatic. Presentation is either due to possible concern about the aetiology or, especially if they are on the face, because of cosmetic effect. Rarely, they may bleed with minor trauma.

They are small lesions with a number of tiny blood vessels radiating from them to resemble the legs of a spider. The centre is about 1 mm in diameter and the whole lesion about 5-10 mm across. Firm pressure with a glass slide or something small, such as the end of an opened paper clip, will cause it to blanch and when the pressure is released it will rapidly refill from the central arteriole.

Lesions most frequently occur on the face, below the eyes, and over the cheekbones. Other common sites include the hands, forearms and ears. Spider naevi may occur on the trunk, or on the scalp, neck, arms and hands. Almost all spider naevi occur on the upper part of the body and only 1% below the umbilicus. Traditional teaching is that they are restricted to areas drained by the superior vena cava but this is disputed by William Bean, one of the great founders of hepatology. Although healthy individuals may have one or more lesions, the presence of large numbers suggests underlying disease. Look for other stigmata of liver disease.
