Port wine stains (PWS) affect 0.3-0.5% of both sexes of newborns, usually occurring on the face.
To document safety and effectiveness of cryogen spray cooled, pulsed-dye laser at higher fluences than previously used to lighten facial PWS in infants < or =6 months, and establish that frequent treatment early in life yields better clearance than if delayed until later in life.
Forty-nine infants who had been treated with pulsed-dye laser treatments for facial PWS at < or =6 months were identified by case review of photographs, age, sex, PWS severity score prior to laser treatment, number of treatments, and improvement following laser therapy.
Patients averaged 9.3 (range 2-16) treatments at 4-6 week intervals at 7.75-9.5 J/cm(2). Average surface area treated was 24.0% with 88.6% average clearance after 1 year. Average clearance was 90.7% for lesions covering <20% surface area and 85.6% for lesions > or =20%. Location (V1, V2, V3, eye, and/or scalp), treated surface area, treatment number, and fluence predicted clearance. Average clearance for sole involvement of V1 was highest (at 93.8%), followed by V2 (at 91.1%), V3 (at 84.3%), V1/V2 (at 83.7%), V1/V2/V3 (at 81.0%), periocular (at 88.6%), and scalp (at 89.9%). All patients tolerated the higher treatment fluences without atrophy or scarring.
DISCUSSION/CONCLUSIONS: Frequent, high energy pulsed-dye laser treatments are safe and highly effective in improving facial PWS in infants < or =6 months of age. Patients with PWS should be referred for pulsed-dye laser treatment during early infancy.
葡萄酒色斑(PWS)在新生儿中男女发病率均为0.3 - 0.5%,通常出现在面部。
记录在高于以往使用的能量密度下,采用冷冻喷雾冷却的脉冲染料激光治疗6个月及以下婴儿面部PWS的安全性和有效性,并证实早期频繁治疗比延迟至后期治疗能获得更好的清除效果。
通过回顾照片、年龄、性别、激光治疗前PWS严重程度评分、治疗次数以及激光治疗后的改善情况,确定了49例6个月及以下接受脉冲染料激光治疗面部PWS的婴儿。
患者平均接受9.3次(范围2 - 16次)治疗,治疗间隔为4 - 6周,能量密度为7.75 - 9.5 J/cm²。平均治疗表面积为24.0%,1年后平均清除率为88.6%。覆盖表面积<20%的病变平均清除率为90.7%,≥20%的病变平均清除率为85.6%。部位(V1、V2、V3、眼部和/或头皮)、治疗表面积、治疗次数和能量密度可预测清除率。仅V1受累时平均清除率最高(为93.8%),其次是V2(为91.1%)、V3(为84.3%)、V1/V2(为83.7%)、V1/V2/V3(为81.0%)、眼周(为88.6%)和头皮(为89.9%)。所有患者均耐受较高的治疗能量密度,未出现萎缩或瘢痕形成。
讨论/结论:频繁、高能量的脉冲染料激光治疗对于改善6个月及以下婴儿的面部PWS安全且高效。患有PWS的患者应在婴儿早期接受脉冲染料激光治疗。
