Clinical and histological evaluation of portwine stain treatment with a microsecond‐pulsed dye‐laser at 577 NM

摘要

AbstractTest treatment of portwine stains (PWS) was performed with a microsecond‐pulsed 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 μsec) laser
