A direct comparison of pulsed dye, alexandrite, KTP and Nd:YAG lasers and IPL in patients with previously treated capillary malformations

Abstract

Alexandrite laser treatment was the most effective, but resulted in hyperpigmentation and scarring in four patients, probably due to its deeper penetration and lower specificity for oxyhaemoglobin causing non-specific dermal damage. Double passing of the PDL can result in further CM fading even in previously treated patients. Videomicroscopy measurements of capillary diameter before treatment may be predictive of the likelihood for patient's to respond to laser treatment.
