Spider veins or varicose veins are unsightly disorders that may occur separately or in tandem. 

Spider veins are small, dilated veins that form web-like or sunburst patterns on the legs and face. Varicose veins are larger dilated blood vessels, which are sometimes raised above the skin. Though not dangerous, both conditions may cause discomfort, and larger varicose veins can be quite painful.

Vein therapy, often performed on an out-patient basis, can be effective in 50 to 90 percent of cases. Treatments include sclerotherapy in which blood vessels are injected with a solution that causes them to shrink and disappear;  laser surgery; ligation (tying off the veins); or complete removal of the affected blood vessels. Several veins may be treated during one visit, and repeated treatments may often be needed, depending on the size of the blood vessels involved.
