Vascular-acting photodynamic therapy (PDT) might be an alternative approach for treating port wine stain (PWS) birthmarks, but the usefulness of PDT for pediatric patients has not been fully investigated.
Medical records of pediatric patients (3-10 years old) with red and purple facial PWS were analyzed. Clinical outcomes after one session of PDL (585 nm, 4.8-6.5 J/cm(2)) and PDT (Hemoporfin - 3.5mg/kg, copper vapour laser - 120 J/cm(2)) were compared.
The rate of excellent response in PDT group was significantly higher than that in PDL group (25.0% vs 10.9%). For red lesions there was no significant difference in overall response between PDL and PDT group, but for purple lesions the overall response rate of PDT group was significantly higher than that of PDL group (93.0% vs 75.6%). Lesions located at the forehead, cheek and jaw regions showed better responses to PDT. Incidences of pigmentation and scar formation in PDT group were significantly lower than PDL group (8.3% vs 21.1%).
This study suggests that PDT is safe and effective for treating facial PWS of childhood patients.
血管作用光动力疗法（PDT）可能是治疗葡萄酒色斑（PWS）胎记的一种替代方法，但 PDT 对儿科患者的有效性尚未得到充分研究。
分析了 3-10 岁面部有红色和紫色 PWS 的儿科患者的病历。比较了单次 PDL（585nm，4.8-6.5J/cm2）和 PDT（血卟啉单甲醚 - 3.5mg/kg，铜蒸气激光 - 120J/cm2）后的临床效果。
PDT 组的优良反应率明显高于 PDL 组（25.0% vs 10.9%）。对于红色病变，PDL 和 PDT 组的总体反应无显著差异，但对于紫色病变，PDT 组的总体反应率明显高于 PDL 组（93.0% vs 75.6%）。位于额部、颊部和下颌部的病变对 PDT 反应更好。PDT 组色素沉着和瘢痕形成的发生率明显低于 PDL 组（8.3% vs 21.1%）。
本研究表明 PDT 治疗儿童面部 PWS 是安全有效的。
