Telangiectasias (spider veins) are usually asymptomatic. However, some patients report a burning sensation or pain, and many people consider even the smallest telangiectasias cosmetically unacceptable.

Diagnosis is clinical.

Treatment of Idiopathic Telangiectasias

  • Sclerotherapy

  • Laser treatment

Laser treatment is effective, but large areas require several treatments. Small telangiectasias may persist or recur after initial treatment.
