目的: 观察长脉冲Nd:YAG激光治疗静脉湖的疗效。方法: 根据病灶大小使用直径5 mm或7 mm的治疗手柄对病灶进行照射治疗, 脉宽15～30 ms, 能量密度90～110 J/cm2。以一个光斑照射后病灶立即由紫红色或紫蓝色转为灰白色并出现皱缩为最佳治疗终点。治疗期间Smartcool冷却系统持续喷洒冷却空气对病灶进行冷却处理。两次治疗间隔不少于2个月。结果: 23例病例一次完成治疗19例, 二次完成治疗3例, 三次完成治疗1例。痊愈15例(60.9%), 显效 9例(39.1%)。5例(20.8%)出现色素减退。无一例治疗无效。结论: 长脉冲Nd:YAG激光治疗静脉湖, 治疗方法简单, 疗效佳, 是一种值得推广的治疗方法。

To observe the effect of long-pulsed Nd:YAG laser in treating venous lakes. Methods: A 1 064 nm long-pulsed Nd:YAG laser (spot size: 5 mm/7 mm, energy: 90～110 J/cm2, pulse duration: 15～30 ms.) was used to treat the patient’s lesions. The desirable clinical endpoint of the treatment was lesions turned pallor and shrunk immediately after the irradiation. Continuous airflow cooling was always applied during the laser treatment. The treatment interval was at least 2 months. Results: Of the 23 patients, 19 of them were treated in one session, 3 of them were treated in two sessions and 1 of them was treated in three sessions. 15(60.9%) of them got excellent results and 9(39.1%)of them got good results. 5(20.8%)of them got hypopigmentation as the side effects. Conclusions: We conclude that it is simple and efficient in treating venous lakes by long-pulsed Nd:YAG laser.
