Port-wine Stain
Conditions
Brief summary
This pilot study aims to evaluate the safety and efficacy of hemoporfin photodynamic therapy (PDT) with different light doses for port-wine stain (PWS)in 2-7 years old children. The pharmacokinetic behavior and pharmacokinetic parameters of hemoporfin in children will be investigated as well.
Interventions
Photodynamic therapy is performed using hemoporfin under general anesthesia. Hemoporfin(5mg/kg)is infused for 20 minutes, followed by light illumination at 10 minutes from the start of infusion. Different light dose of PDT is applied to the patients.
