儿童鲜红斑痣皮肤镜下血管模式与激光疗效的关系

Relationship between dermoscopy vascular pattern and laser efficacy in port wine stains in children

目的:探讨鲜红斑痣皮肤镜下不同血管模式与激光治疗效果的关系。方法:收集2021年6月至2022年6月我院行脉冲染色激光治疗的鲜红斑痣患者,分别在首次治疗前和3次激光治疗结束后1个月,使用数码相机及皮肤镜在同一部位进行拍摄,记录血管模式,并分析皮损面积及颜色的变化,探讨儿童鲜红斑痣皮肤镜下血管模式与激光治疗效果的关系。结果:共收集58例患儿,皮肤镜下可见:线状血管(19例),点球状血管(12例),网状血管(12例),短棒状血管(9例),混合型血管(3例),均一红色背景模式(3例),治疗有效率分别为84.2%,100%,66.7%,100%,66.7%,33.3%,差异有统计学意义(均P<0.05)。结论:脉冲燃料激光治疗不同血管模式的鲜红斑痣疗效不同,点球状、短棒状、线状血管模式疗效较好。

Objective:To investigate the connection between various dermoscopy vascular patterns and the effectiveness of laser therapy for pediatric port-wine stains(PWS).Methods:The data of the patients with PWS treated with laser treatment from June 2021 to June 2022 in our hospital were selected.Photographs taken using a digital camera and a dermatoscope before treatment and 1 month after 3 times of treatment,to compare the vascular pattern and analyse changes in lesion area and colour so as to explore the correlation between the dermoscopy vascular patterns and the effectiveness of laser treatment.The differences in age,type of lesion,site of lesion with dermoscopy vascular pattern were also assessed.Results:In the dermoscopy images of PWS included linear vessels(19 cases),dotted and globular vessels(12 cases),reticular vessels(12 cases),short clubbed vessels(9 cases),mixed vessels(3 cases)and the uniform red regional pattern(3 cases),and the effective rates were 84.2%,100%,66.7%,100%,66.7%,33.3%respectively,with significant differences(P s<0.05).Conclusion:The therapeutic effect of pulsed fuel laser is different in the treatment of bright red nevus with different blood vessel patterns,and the model of spot ball,short rod and linear blood vessel are better.
