Laser recannalization of atheromatous vessels using fiber optics.

abstract：BACKGROUND/OBJECTIVES:Current laser therapy of port wine stain (PWS) birthmarks with a single laser pulse (SLP) does not produce complete lesion removal in the majority of patients. To improve PWS therapeutic efficacy, we evaluated the performance of an approach based on multiple laser pulses (MLP) to enhance blood ves...
