Paper Abstract

Tne feasibility of welding thin-walled microvessels by laser has been established. This report summarizes our experience using laser welding to repair thick-walled, large-diameter, 4 to 8 mm canine veins and arteries using CO2, Nd:YAG and argon lasers. Welding of venotomies is uniformly successful using CO2 and Nd:YAG lasers, and Nd:YAG venotomies appear to veal more rapidly than sutured controls. Arterial welding has been accomplished with the Nd:YAG and argon laser. Our preliminary experience shows promise for welding both large diameter veins and arteries using lasers. Laser welding may represent an alternative for repair of small and large diameter vessels with several advantages compared to conventional suture techniques.
