目的 探讨光动力疗法联合脉冲染料激光治疗紫红型和增厚型鲜红斑痣的临床疗效.方法 对238例紫红型和增厚型鲜红斑痣患者静脉推注血卟啉单甲醚(HMME)315~510 mg/kg,5 min内行铜蒸气激光照射(激光功率密度80~100 mW/m2,光斑直径8~9 cm,照射20~40min,能量密度120~240 J/cm2),病变变浅或分散后,再结合脉冲染料585 nm激光对皮损进行局部治疗.结果 238例患者中,痊愈42例,显效118例,改善78例.总有效率为67.2%.7例患者出现暂时性色素沉着,严格防晒并口服维生素C,1~6个月自然消退.结论 光动力疗法联合585 nm激光治疗紫红型和增厚型鲜红斑痣,疗效比单一方法有较大提高,且安全,值得临床推广应用.
