Paper Abstract

Laser assisted microvascular anastomosis with a variety of lasers has been reported to provide shorter operating times, less tissue reaction and possibly better long term patency rates. We describe our experience using a pulsed thulium-holmium-chromium:YAG laser (2.15 micron) to construct sutureless microvascular anastomoses. The intermediate absorption of this wavelength compared with CO2 and Nd:YAG lasers, allows uniform heating of the vessel wall. End-to-end anastomoses of 10 rat carotid arteries were created with the THC:YAG laser. Histologic sections of anastomosed vessels confirmed full thickness fusion of the media with minimal thermal damage. Bursting pressures were all in excess of 300 mm Hg. The THC:YAG laser creates vascular fusion of sufficient immediate strength to perform microvascular anastomosis.
