Clinical Comparison of Sclerotherapy Versus Long-Pulsed Nd:YAG Laser Treatment for Lower Extremity Telangiectases.

摘要

BACKGROUND: Sclerotherapy has traditionally been considered the gold standard of treatment for leg veins, but patient fear of multiple needle injections and side effects of treatment have fueled investigation into other treatment alternatives. As a result, vascular-specific laser and light sources have been developed in an effort to treat these vessels with minimal morbidity and improved efficacy. OBJECTIVE: To compare the clinical efficacy of leg telangiectasia treatment with sodium tetradecyl sulfate sclerotherapy to long-pulsed 1064 nm Nd:YAG laser irradiation. METHODS: A series of 20 patients with size-matched superficial telangiectases of the lower extremities were randomly assigned to receive two consecutive monthly treatments with injectable sodium tetradecyl sulfate on one leg and long-pulsed 1064 nm Nd:YAG laser irradiation on the other. Patients were evaluated by two masked assessors at each treatment visit and at 1 and 3 months after treatment to assess clinical improvement within matched sites. RESULTS: Leg telangiectases responded best to sclerotherapy in fewer treatment sessions than to long-pulsed 1064 nm Nd:YAG laser irradiation. The incidence of adverse sequelae was minimal and equivocal in both treatment groups. CONCLUSION: Despite recent advances in laser technology for treatment of lower extremity telangiectases, sclerotherapy continues to offer superior clinical effect in the majority of cases. Laser leg vein treatment appears to be most beneficial in patients with telangiectatic matting, needle phobia, or sclerosant allergy.
