LASER TREATMENT OF ACQUIRED VASCULAR LESIONS

Abstract

Several quasi-continuous wave and pulsed lasers can effectively treat a variety of vascular lesions. The PDL follows the theory of selective photothermolysis, is safe for infants and children, and has a low incidence of side effects. It is successful in treating telangiectasias, spider and cherry angiomas, pyogenic granulomas, venous lakes, and poikiloderma of Civatte, as well as small leg telangiectasias. Quasi-continuous wave lasers such as the APTDL, copper vapor, krypton, and KTP lasers can be used to treat telangiectasias and other vascular lesions as well. Although they carry a higher risk of complications, they may prove more useful in treating larger caliber vessels. Although the PDL often produces superior clinical results than the quasi-continuous wave lasers, some patients may prefer these latter lasers because of the lack of post-operative purpura. Lastly, newer lasers, as well as noncoherent light sources, are being developed for the treatment of leg telangiectasias. Continuing advances in laser technology will enhance results, decrease side effects, improve equipment, and reduce costs, with great benefit to an increasing patient population.
