As a kind of congenital vascular malformations, Port Wine Stain (PWS) is composed of ectatic venular capillary blood vessels buried within healthy dermis. In clinic, Pulsed Dye Laser (PDL) in visible band (e.g. 585 or 595 nm) together with cryogen spray cooling has become the golden standard for treatment of PWS. However, due to the limited energy penetration depth of the PDL, deeply buried blo...

BACKGROUND The current modality of choice for the treatment of Port-wine stains (PWS) is laser photocoagulation. Laser therapy for the treatment of PWS, especially with a pulsed dye laser (PDL), has been proven safe and effective; however, because penetration of the PDL is too shallow for an effective ablation of the blebs, treatment of blebbed PWS, using PDL, may be insufficient. OBJECTIVE W...

Organic lasers came into existence via the introduction of the pulsed optically-pumped liquid organic dye laser by Sorokin and Lankard (1966) and Schäfer et al. (1966). An additional momentous contribution was the discovery of the continuous wave (CW) liquid organic dye laser by Peterson et al. (1970) which opened the way for the development of narrow-linewidth tunability in the CW regime plus ...

A retrospective study of 502 patients treated with tunable flashlamp pulsed dye laser for superficial vascular malformations (433), ulcerated hemangiomas (65) and postinvolutional redness (4) is presented. Patients were treated in the period from June 1997 to March 2006, with follow-up ranging from six months to four years. The age of the patients ranged from three months to 80 years. Correlati...

Objectives: To compare between pulsed dye laser and podophyllin resin in treatment of genital warts regarding pain, number of sessions, clearance rate, and recurrence. Methods: Thirty-nine female patients were divided into two groups, the first group; 20 patients was treated with podophyllin resin, the second group 19 patients was treated with pulsed dye laser (Candela) 595nm, 1.5 ms pulse dura...

Background and aim : The clinical management of verrucae vulgaris is often challenging and no treatment is always effective. Early studies have suggested that pulsed-dye laser (PDL) may be highly effective in the treatment of verrucae through obliteration of dilated vessels in papillary dermis. The objective of this study was to compare safety and efficacy of 585 nm with 595 nm PDL in the...
