Introduction: Port wine stains (PWS) are congenital vascular malformations. Pulsed dye laser (PDL) is the treatment of choice till now, although many lesions do not respond completely. One of possible options is long pulsed alexandrite laser. Some literatures confirmed its efficacy. The aim of the present study is to determine the efficacy of this laser as an option in treating refractory PWS in Iranian patients. Methods: Patients with refractory PWS lesions that did not respond to at least six… Expand

Numerical Modeling and Clinical Evaluation of Pulsed Dye Laser and Copper Vapor Laser in Skin Vascular Lesions Treatment.
Based on calculated and clinical data, the heating mode for dysplastic vessels using a series of CVL micropulses could be regarded to be safer and more efficient than the mode of a PDL short, powerful pulse. Expand


Alexandrite Laser for the Treatment of Port Wine Stains Refractory to Pulsed Dye Laser
In this pilot study, PDL‐resistant PWS responded significantly to a series of MSPAL treatments, and treatment with conservative parameters and close observation of tissue response are essential. Expand
Treatment of port wine stains using the pulsed-dye laser at 585 nm with the dynamic cooling device
A case of a 29-year-old white male with extensive PWS, which displayed only mild changes with the first generation PDL, is reported, where the use of the 1.5 ms PDL at 585 nm at high fluences in conjunction with the DCD resulted in marked improvement of the patient's PWS. Expand

It is important to attain, and maintain, the correct endpoint when treating PWS with this deeply penetrating near‐infrared laser at high fluences in order to (a) induce lesional lightening, and (b) avoid deep dermal burns that may produce scarring. Expand

Port wine stains (PWS) are heterogeneous vascular malformations that can be treated with vascular‐selective pulsed dye lasers (PDL). Hypertrophic PWS, especially in adults, are consistently lessExpand
Treatment of Port-Wine Stains with the Flashlamp-pumped Pulsed Dye Laser: Extended Clinical Experience in Children and Adults
While the 585 nm pulsed dye laser continues to be the treatment of choice for removal of PWS in children and adults, the number of treatments necessary to obtain lesional clearing in all age groups is greater than previously reported. Expand
Treatment of pulsed dye laser-resistant port wine stain birthmarks.
These include higher power, longer wavelength, variable pulse width lasers with selective epidermal cooling such as 595-nm PDL, 755-nm alexandrite, 810-nm diode, 1064-nm neodymium:yttrium-aluminum-garnet, and intense pulse light systems. Expand
Pulsed alexandrite laser for the treatment of leg telangiectasia and reticular veins.
A single treatment with a 755-nm, 3-millisecond alexandrite laser at high fluence in conjunction with cryogen skin cooling produced excellent clearance of telangiectasia and reticular veins of the leg with minimal adverse effects. Expand
585 nm for the treatment of port-wine stains.
Parallel treatment of different sites of the same lesion coupled with skin biopsies and histologic examination revealed that a change in the wavelength from 577 to 585 nm allowed the laser light to penetrate from the midreticular dermis into the subcutaneous fat. Expand
Comparison study of a long‐pulse pulsed dye laser and a long‐pulse pulsed alexandrite laser in the treatment of port wine stains
LPPAL works best with hypertrophic, purple P WSs, while LPPDL yields better clinical improvements with the flat, pink PWSs. Expand
