title: Evaluation of the treatment of venous lakes with the 595-nm pulsed-dye laser: a case series.
abstract: Venous lakes (VLs) are common benign venous ectasias in the upper dermis. They are treated to improve cosmesis and occasionally to prevent bleeding. Numerous methods have been used, such as cryotherapy, infrared coagulation and various types of lasers. They are variable in their success and all can be complicated by scarring. We report our experiences of using the 595 nm pulsed-dye laser (PDL), which has not been previously described. Eight patients were treated but sufficient resolution was achieved in only three patients. The limited success with this laser could be attributed to insufficient thermal energy being generated to close all the blood vessels permanently. A large prospective study would provide further data regarding the efficacy of the PDL. The use of compression and longer pulse durations may improve the efficacy of the 595 nm PDL to treat VLs.
