✦ Synopsis

Test treatment of portwine stains (PWS) was performed with a microsecondpulsed dye laser at 577nm using a 2-mm spot diameter. Although selective coagulation of the erythrocytes occurred, this did not result in bleaching of the treated area. Massive destruction of the dilated capillaries is suggested to be a prerequisite for PWS-bleaching. very probably requiring msec (instead of psec) laser pulses.
