Treatment of vascular lesions with combined dynamic precooling, postcooling thermal quenching, and ND:YAG 1,064-nm laser

Abstract

The purpose of this study is to evaluate the effectiveness and safety of the newly developed neodymium:yttrium-aluminum-garnet (Nd:YAG) 1,064-nm laser system for nonablative laser treatment of vascular lesions in Asians. Five patients with vascular lesions in the periorbital area received serial treatments. The fluences were set between 80 and 90 J/cm(2). The patients were followed for 6 months. Improvements were noted in all patients. Transient erythema and swelling were noted in all patients during the postoperative period. Transient purpura occurred in one patient. The Nd:YAG 1,064-nm laser system, when coupled with dynamic precooling and postcooling thermal quenching, is effective and safe in treating periorbital vascular lesions even when multiple treatments are performed. No significant adverse effects were noted in this study.
