Pulsed alexandrite laser for the treatment of leg telangiectasia and reticular veins

Arch Dermatol. 2000 Nov;136(11):1371-5. doi: 10.1001/archderm.136.11.1371.

Abstract

Objective: To examine the safety and efficacy of a pulsed alexandrite laser for treatment of leg telangiectasia and reticular veins.

Design: Observational study.

Setting: Laser and Skin Surgery Center of New York, New York, NY.

Subjects: Twenty women with skin phototypes I to III and with 54 patches of leg veins measuring 0.3 to 2.0 mm in diameter.

Interventions: Each patch was treated once using 1 to 3 passes of a 755-mm, 3-millisecond alexandrite laser. An 8-mm spot and fluences of 60 to 80 J/cm(2) were used, with dynamic epidermal cooling.

Main outcome measures: Subjects underwent evaluation at 4 and 12 weeks for degree of clearance, based on a quartile grading system, and incidence of adverse effects.

Results: At the 4-week follow-up, 17 (35%) of 48 treatment sites showed greater than 75% clearance and an additional 16 (33%) showed greater than 50% clearance. By 12 weeks, 33 (65%) of 51 treatment sites showed greater than 75% clearance, and there was greater than 50% clearance in an additional 11 (22%). Hyperpigmentation was observed in 18 (35%) of 51 treatment sites.

Conclusion: A single treatment with a 755-nm, 3-millisecond alexandrite laser at high fluence in conjunction with cryogen skin cooling produced excellent clearance of telangiectasia and reticular veins of the leg with minimal adverse effects.
