背景和目的：由于鲜红斑痣的异质性，其中许多对脉冲染料激光（PDL）治疗具有抵抗力。一种新的可变脉冲持续时间 PDL 可改善难治性鲜红葡萄酒色斑。 研究设计/材料和方法：一名患有先天性鲜红葡萄酒色斑的 26 岁男性接受了 8 次 1.5 毫秒脉冲持续时间 PDL 治疗，但效果甚微。然后使用 3 毫秒脉冲持续时间 PDL 进行单次治疗。结果：使用 3 毫秒脉冲持续时间 PDL 对该患者的鲜红斑痣进行治疗的初步结果显示，先前以显着更高的能量密度、相同的光斑大小、但脉冲持续时间减半的治疗区域中的区域得到了显着的清除。结论：一旦鲜红斑痣或部分鲜红葡萄酒染色变得难治，血管异质性可能需要改变脉冲持续时间。脉冲持续时间。
BACKGROUND AND OBJECTIVES: Because of the heterogeneity in port-wine stains, a number of them prove resistant to treatment with the pulsed-dye laser (PDL). A new variable pulse-duration PDL improves a refractory port-wine stain.STUDY DESIGN/MATERIALS AND METHODS: A 26-year-old man with a congenital port-wine stain underwent eight treatments with the 1.5-ms pulse-duration PDL resulting in minimal improvement. A single treatment was then administered with the 3-ms pulse-duration PDL.RESULTS: Initial results of treatment with the 3-ms pulse-duration PDL on this patient's port-wine stain show dramatic clearance in areas previously treated with significantly higher fluences, an identical spot size, but with a pulse duration half as long.CONCLUSION: Vessel heterogeneity may require changing pulse durations once a port-wine stain or a portion of a port-wine stain becomes refractory to given pulse-duration.
