ReferencesFlash‑lamp pulsed dye laser (FPDL) 目前被广泛认为是可用于治疗表面血管问题的最精确的激光。在这项研究中，我们收集了十年来使用染料激光治疗各种血管疾病患者的经验数据（telangiectasia、rhinophyma、port‑wine stains、cherry and spider angiomas，以及血管肿瘤如 cherry angiomas、infantile hemangiomas、port‑wine stains、rhinophyma、spider angiomas、telangiectasia）。
The Flash‐lamp pulsed dye laser (FPDL) is nowadays considered the most precise laser currently on the market for treating superficial vascular lesions. In this study, we gathered data from 10 years of experience regarding dye laser treatment of patients presenting vascular malformations such as telangiectasia, rhinophyma, port‐wine stain, cherry and spider angioma and vascular tumours: cherry angioma, infantile haemangioma, port wine stain, rhinophyma, spider angioma, telangiectasia

Port-wine stain (PWS) 也称为 nevus flammeus。它是婴儿皮肤上由异常血管引起的粉红色或红色斑块，出生时即存在并终生保留，常见于面部。需与单纯痣或鲑鱼斑区分，后者会随时间逐渐褪色。
Nevus flammeus or port-wine stain (PWS) is a non-neoplastic congenital dermal capillary hamartomatous malformation presenting as a pink or red patch on a newborn's skin. It is a congenital skin condition that can affect any part of the body and persists throughout life. The nevus flammeus is a well-defined, often unilateral, bilateral, or centrally positioned pink to red patch that appears on the face at birth and is made up of distorted capillary-like vessels. It needs to be differentiated from a nevus simplex/salmon patch, which is usually seen along the midline and disappears over time. An acquired port-wine stain, clinically and histopathologically indistinguishable from congenital capillary malformation, has been reported to develop in adolescents or adults, usually following trauma.

治疗 PWS 对于降低其对心理健康的影响以及减少结节和组织肿大非常重要。尽早开始治疗可能会取得更好的效果。Pulsed dye laser (PDL) 被广泛认为是所有类型 PWS 的最佳选择，无论其大小、位置或颜色。
Treatment of PWB is indicated to minimize psychosocial impact and diminish nodularity, and potentially tissue hypertrophy. Better outcomes may be attained if treatments are started at an earlier age. In the United States, pulsed dye laser (PDL) is the gold standard for all PWB regardless of the lesion size, location, or color. When performed by experienced physicians, laser treatment can be performed safely on patients of all ages. The choice of using general anesthesia in young patients is a complex decision which must be considered on a case by case basis.

焰色痣 (Portwine stain) 最常出现在面部，也可能出现在身体的任何部位，尤其是颈部、上半身、手臂和腿部。早期病灶通常呈扁平的粉红色。随着儿童成长，颜色可能加深为深红或紫色。成年后，病变可能增厚或形成小结节。
○ 治疗
血管激光可取得一定效果，但需要昂贵的激光设备并进行数年的长期治疗。由于病变随年龄增长而变厚，激光疗效可能下降，这是一大挑战。粉红色病灶通常比红色病灶更难治疗，因为其血管位于更深层。
