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:We demonstrated the clinical efficacy of a 1,064 nm long pulsed Nd:YAG laser with contact cooling device for blebbed PWS. Methods: Twenty one patients with blebbed PWS (Fitzpatrick skin types II-V) underwent a treatment,using a 1,064 nm long pulsed Nd:YAG laser with a contact cooling device at 8-week intervals. Treatments were done using 5∼6 mm spot sizes at 20∼30 ms and 95∼170 J/cm2. Laser parameters were adjusted in order to meet the needs of each individual patient’s lesions. Results: All subjects tolerated the treatments well, and showed clinical improvement from blebs. Of the 21 patients, 18 of them experienced either moderate or excellent response. Conclusion: Use of a 1,064 nm long pulsed Nd:YAG laser results in a greater depth of vascular coagulation. A 1,064 nm long pulsed Nd:YAG laser with contact cooling device may be regarded as a promising therapeutic option for the treatment of blebbed PWS.
