- W4246307493 abstract "Therapies for port wine stains including conventional laser irradiation usually cause unacceptable scarring or obtain poor effect. Pulsed dye laser has better approach, but only few patients obtain complete fading after multiple laser treatment. Because port wine stain is a congenital vasculopathy consisting of an abnormal network of capillaries in the upper dermis with an overlying normal epidermis and the researchers found that tumor blood vessels were occluded accompanying the necrosis of the tumor after PDT. It is though to be the effect primarily by thrombus formation in vessels and shut down of the blood supply to the tumor as well as direct tumor cells kill. The author and his colleagues started a series of animal and clinical studies since 1991 about photodynamic therapy for port wine stains and they established the method of PDT for PWS. An experimental study showed that Hpd appeared rapidly within the human vascular endothelial cells in culture fluid. Animal study using chicken combs as PWS models treated by PDT revealed the possibility of selective destruction of the malformative vasculature in PWS. The clinical studies of over 1700 cases proved that PWS can be cured without scar formation by PDT because there is no thermal effect involved. No relapse was found within a maximum follow-up of seven years. The differences and mechanism between the treatments of PDT and conventional lasers are discussed." @default.
