585nm脉冲染料激光治疗顽固的病毒性疣

TREATING RECALCITRANT VIRAL WARTS BY 585nm PULSED DYE LASER

目的 :探讨一种治疗顽固的病毒性疣的有效治疗方法。 方法 :用 5 85 nm的脉冲染料激光 (PDL)照射患区及其周围 5 mm内的区域连续三个脉冲 ,能量范围 6～9J/ cm2 ,照射前先用最小能量连续脉冲的 CO2 激光除去疣表面的角质层 ,以使 PDL 光进入更深层。 结果 :治疗 38例病人 16 3个顽固性疣和 30个单纯性疣 ,根治率分别为95 %及 90 % ,经过 3～ 2 6个月 (平均 8个月 )的随访 ,未再复发。 结论 :利用疣内血管中的血红蛋白吸收 5 85 nm波长的激光后凝固 ,使血管闭锁的原理 ,可有效地治疗病毒性疣 ,且不遣留瘢痕。尤其适合于面。

Objective:To investigate an effective and safe way for treating viral warts,especially for recalcitrant warts Methods:Pulsed dye laser(PDL)at 585 nm with fluencies of 6 0～9 0J/cm 2 was used for three passes each area Prior to laser treatment,the keratotic component of the warts were removed by continual pulsed CO 2 laser with the smallest energy,in order to allow deeper penetration of the laser beam into the warts Results:38 patients with 163 recalcitrant and 30 simple viral warts were treated with 585nm PDL,which achieved eradication rate of 95% for recalcitrant warts after an average 2 1(range 1～6)treatments and 90% for simple warts after 1 3(range 1～2)treatments There is no recur after 3～26 months following up Conclusions:[WT5”,6BZ]Pulsed dye laser(PDL) is an effective treatment for bothrecalcitrant and simple warts For its scarless,it is the treatment of better choice for these lesions in cosmetically sensitive areas
