[Laser treatment of port wine stain].
Laser treatment of vascular skin lesions is rapidly improving. Port wine stain (PWS) is one of the first lesions successfully treated with laser. The pulsed dye laser (PDL) has been developed on the concept of selective photothermolysis and has revolutionized PWS treatment. Even though the response is variable, substantial blanching can be obtained after several sessions. Greater selectivity an...

متن کاملReal-time photothermal imaging and response in pulsed dye laser treatment for port wine stain patients.
BACKGROUND This study was performed to assess the photothermal response of highly focused laser energy using infrared thermal imaging instrument to detect and assess the actual temperature distribution during flash lamp pumped pulsed dye laser (FLPPDL) treatment for port wine stain (PWS) patients and avoiding its complications. METHODS A retrospective review of 40 patients with PWS birthmark ...
متن کاملAcquired Port-Wine stain: Report of two cases
Acquired port-wine stain is a rare vascular lesion that mimics a congenital port-wine stain clinically and histologically, but is acquired after birth. A survey on more than 60 reported cases in the literature reveals that most of these cases are idiopathic, but some of the cases developed after physical or mechanical trauma, hormonal changes, chronic sun exposure, and medications (OCP, i...
متن کاملNoninvasive blood flow imaging for real-time feedback during laser therapy of port wine stain birthmarks.
BACKGROUND AND OBJECTIVES During laser therapy of port wine stain (PWS) birthmarks, regions of persistent perfusion may exist. Immediate retreatment of such regions may improve PWS laser therapeutic outcome. To address this need, we propose use of laser speckle imaging (LSI) to provide real-time, quantitative feedback during laser surgery. Herein, we present in vitro and in vivo data collected ...
