目的 研究波长 5 32nm可调脉宽 (VPW )HELP G(高能量长脉宽绿光 )激光治疗鲜红斑痣的临床疗效和病理改变。方法 对 32例鲜红斑痣进行激光治疗并随访观察 ,治疗参数由普通VPW (3mm ,11~16J/cm2 ,7~ 10ms)逐渐到HELP G(4~ 5mm ,16~ 2 4J/cm2 ,15~ 5 0ms) ,并观察了其中 2例的组织病理改变。结果 32例鲜红斑痣经过 1~ 8次 (平均 3 .19次 )治疗 ,治愈 7例 ,显效 15例 ,有效 8例 ,无效 2例 ,总有效率 6 8.75 %。结论 可调脉宽HELP G激光治疗鲜红斑痣疗效较好。
Objective To treat a group of patients with port wine stains (PWS) using a variable pulse width (VPW) frequency doubled Nd:YAG 532nm with high energy long pulse green (HELP G) laser and to evaluate the clinical efficacy, side effects and different histological changes between VPW and HELP G. Methods Thirty two patients with PWS were treated in order to study the clinical improvement by transforming from 11~16 J/cm 2 at 3 mm spot size (VPW,7~10 ms) gradually to 16~24 J/cm 2 at 4~5 mm spot size (HELP G,15~50 ms). Two patients were biopsied before and after the laser treatment.Results After treatment of 1~8 times(3.19 average), very good results were achieved in 7 PWS, and excellent results were achieved in 15 PWS.Improvement was found in 68.75 % of the patients.Conclusion VPW with HELP G laser at 532 nm appears to be an effective treatment for PWS.
