目的探讨长脉冲可调脉宽Nd:YAG激光治疗毛细血管瘤的疗效及影响因素.方法长脉冲可调脉宽Nd:YAG激光治疗毛细血管瘤患者124例,根据皮损面积、颜色、深浅选择参数,并根据即刻反应调整参数.治疗间隔1个月.结果 135个皮损的治愈率为74.07%,有效率为90.37%.各因素对疗效的影响:皮损面积越小,有效率越高(P<0.01),部位及皮损厚度的不同对疗效无影响(均为P>0.05).不良反应:术后水疱发生率为8.89%,萎缩性瘢痕发生率为2.96%.结论长脉冲可调脉宽Nd:YAG激光治疗毛细血管瘤效果好,不良反应小,是治疗毛细血管瘤的有效方法之一.

Objective To evaluate the efficacy of long-pulsed tunable Nd: YAG laser on capillary hemangioma and to analyse its influencial factors. Methods A retrospective review was conducted on 124 patients with 135 vascular lesions treated with long-pulsed tunable Nd:YAG laser from February, 2007 to January, 2008. Working parameters, including spot size (3-5 mm), pulse duration (10-30 ms) and fluence (120-200 J/cm2) were determined based on the size, color and depth of lesions and adjusted according to the immediate reaction of lesions. The interval of two treatments was 1 month. Results Of the 135 lesions, 100 experienced a more than 95% subsidence, 22 achieved 60%-94% subsidence, 11 got 30% -59% subsidence, and 2 reached less than 30% subsidence. The cure rate and effective rate were 74.07% and 90.37% respectively. Smaller lesions showed a better response to the treatment than larger ones (P<0.0001), whereas the sites and depth of lesions had no effect on the efficacy (both P>0.05). Atrophy scar occurred in 4 (2.96%) lesions, and blisters in 12 (8.89%) lesions after the treatment. No purpura or pigmentary changes occurred. Conclusion The long-pulsed tunable Nd:YAG laser is an effective treatmnt for capillary hemangioma with fast action and few side reactions.
