对维纳斯VPW532nm激光治疗鲜红斑痣的临床评价

Clinical Evaluation of the Therapeutic Effect of VPW 532 um Laser of Vecsapulse C on Port - wine stains

目的：评价维纳斯激光治疗仪可调脉宽（ＶＰＷ）５３２ｎｍ激光治疗鲜红斑痣的临床疗效。方法：用维纳斯激光治疗仪中的倍频５３２ｎｍ激光在７～１４丁／ｃｍ~２能量、７～１０脉宽、４～５℃冷却头温度的条件下治疗鲜红斑痣，同一患者每２～３月进行１次治疗。结果：１５７例鲜红斑痣中，治疗了１次的患者共６０例，其中弱效（颜色消退小于２５％）３８例（６３．３％），有效（颜色消退２５～５０％）１７例（２８．３％），显效（颜色消退５０～９０％）５例（８．３％）；治疗了２次的患者共４５例，其中无效８例（１７．８％），有效１５例（３３．３％），显效１６例（３５．５％），痊愈（颜色消退近１００％）６例（１３．３％）；治疗了３次的患者共３７例，其中无效１例（２．７％），有效１３例（３５％），显效１２例（３２．４％），痊愈１１例（２９．７％）；治疗了４次的患者共１２例，有效９例（７５％），显效２例（２２．２％），痊愈１例（１１％）；治疗了５次的患者共３例，３例患者均只达到显效。激光治疗的总有效率７０％，总痊愈率１１．５％。共有４例（２．５％）治疗后出现局限性疤痕。结论：维纳斯ＶＰＷ５３２ｎｍ激光治疗鲜红斑痣安全有效，但痊愈率较低。

Objective: To evaluate the clinical result in treating patients with Port - wine stains. Methods: Patients with port wine stains were treated by means of Versapulse C device with double frenquency Nd: YAG 532urn laser through a chilled tip (tem- perature controlled between 4 - 5℃) with 7 - 14J/cm^2 energy and 7 - 10ms pulse width. Each patient was treated once every 2 - 3 months. Results: 60 of the 157 patients with port - wine stains, received once laser trentment, of which 38 patients (38.3% ) had weak repowse (< 25% decoloration ) and 17 patients (28.3% ) good respowse (25 - 50% decoloration) and 5 patients (8.3%) excellent response (50 - 90% decoloration), 45 patients received received twice laser treatment, of which 8 patients (17.8% ) had weak respowse and 15 patients (33.3%) good response and 16 patients (35.5%) excellent response and 6 patients (13.3%) cured(nearly 100% decoloration), 37 patients received 3 times laser treatment, of which 1 patient (2.7% ) had weak response and 13 patients good response (35% ) and 12 patients (32.4%) excellent response and 11 patients (29.7%) cured. 12 patients received 4 times laser treatment, of which 9 patients (75% ) had good response and 2 patients (22.2% ) excellent meponse and 1 patient (11% ) cured. All 3 patients receiving 5 times laser treatment showed good response.The total effect rate was 70% and total cared rate was 11.5% .4 patients (2.5% ) had localized scar after laser treatment. Conclusions:Versapulse C device is safe and effective in treating port - wine stains, but the curative rate is low. ms equipment has limitation in this aspect.
