Tunable pulsed dye laser for the treatment of benign cutaneous vascular ectasia

A tunable pulsed dye laser emitting at 577 nm and 360 microseconds pulse width was used to treat benign cutaneous vascular ectasias other than port wine stain in 77 patients. Except for leg telangiectasias (34 patients), the overall response was excellent. Forty-two of forty-five patients with hemangiomas, spider nevi, angioma serpiginosum, venous lakes or facial telangiectasias showed excellent results after 1-4 consecutive treatments. Scarring was observed in none of the patients. These results confirm previous data on the use of the tunable dye laser in the treatment of port wine stain, and suggest that 577 nm wavelength and 360 microseconds pulse width allow the selective photothermolysis of vascular cutaneous ectasias with better clinical results than previously reported.
