目的 评价长脉宽Nd:YAG激光治疗浅表静脉畸形的疗效和安全性。方法 前瞻性纳入18例浅表静脉畸形患者,采用长脉宽Nd:YAG激光进行治疗,治疗间隔2个月,治疗终点为病灶清除率大于90%,采用治疗前后照片对比进行疗效评价。记录水泡、色沉、毛细血管扩张和瘢痕等不良反应。治疗结束后随访12个月,评价复发率,复发判定标准为治疗后的区域复现10%以上的蓝色血窦。结果 经过1～4次(平均2.4次)的治疗,全部患者均可达到90%以上的病灶清除率。不良反应:水泡3人4例次,色素沉着5人9例次,毛细血管扩张3例;无瘢痕增生病例,无复发病例。结论长脉宽Nd:YAG激光可有效治疗浅表静脉畸形,是一种安全有效的方法。

Objective To evaluate the efficacy and safety of long-pulse Nd:YAG laser therapy for superficial venous malformations.Methods Eighteen patients with superficial venousmal formations were included in this study prospectively.They were treated by long-pulse Nd:YAG laser at an interval of 2 months.The end point of treatment is when the lesion clearance rate is over 90%evaluated by photographs taken before and after therapy.The complications were recorded including blister,pigmentation,telangiectasia and hypertrophic scar.After 12 months of follow-up,the recurrence rate was defined as more than 10%lesion reappeared at their original locations.Results After 1-4 sessions(average 2.4 sessions)treatment,at least 90%could been removed for each lesion.Blister was seen in 4 sessions of 3 cases,pigmentation in 9 sessions of 5 cases,telangiectasia in 3 cases and no scarring.No recurrence was observed.Conclusion Long-pulse Nd:YAG laser is effective and safe for treating superficial venous malformations.
