Clinical experience with the pulsed-dye laser in the treatment of capillary malformations (port-wine stains): a preliminary report.

This preliminary report reviews a series of 70 patients treated with tunable-dye laser therapy for congenital capillary malformations (port-wine stains). Results were reviewed according to age and ethnic group of patients and color and anatomical location of malformations. Red birthmarks were most responsive to treatment in all age groups in all anatomical locations. Purple birthmarks were generally less responsive to laser treatment except in children, who responded well. Scarring and hypopigmentation were minimal (5.7% and 1%, respectively), even in nonwhite patients. Recommendations emerging from this study include testing of infants, as results may vary. Detrimental side effects are rare. A major goal in treating port-wine stains is to avoid both the progression of these lesions through life and the psychological complications that occur during early socialization years in childhood. Pulsed-dye laser treatment offers much promise in these areas.
