Abstract
OBJECTIVES: To observe the clinical efficacy of photodynamic therapy mediated by hemoporfin (HMME-PDT) for port-wine stains (PWS) on extremities and explore its possible influencing factors. METHODS: Four patients with PWS in extremities were treated by HMME-PDT, and patients with negative results in the skin test were given an intravenous injection of 5 mg/kg of HMME. The patients were irradiated with 532 nm LED green light, and immediately applied cold compress after treatment. These patients were informed to stay away from light for two weeks. A follow-up every 2 weeks was conducted with treatment for 2 or 3 times in total. After the end of treatment, a follow-up was carried out for 6-12 months and the efficacy and safety were evaluated. RESULT: Three of the four patients were considered cured, and the treatment was ineffective for one patient. During the follow-up observation, all patients had different degrees of edema, and there were no signs of chromatosis or scarring. CONCLUSION: PDT treatment for patients with extremity PWS demonstrate high efficiency and safety, without obvious adverse reactions and recurrence.
