ABSTRACT
Tissue fusion using laser welding has been evaluated in several applications; cosmetic closure of skin incisions, sutureless repair of enterotomies, anastomoses of the trachea, vas deferens and Fallopian tubes. Laser vascular tissue welding is an evolving, promising new technology with many advantages; healing without foreign body reaction, decreased incidence of intimal hyperplasia and unrestricted enlargement of growing vessels. Laser vascular tissue welding has been investigated in small and medium sized vessels in experimental and few clinical studies. Trials to improve the result of laser vascular welding led to important technical refinements. Proper selection of the suitable laser wave-length, the use of pulsed laser, the use of solders and photo enhancers, automated control of laser dosimetry and closed loop feed-back control are new innovations. This work aimed at reviewing the literature of laser vascular tissue welding. Laser welding trials were conducted on 10 rabbits aorta and 5 goats femoral arteries using argon laser with favourable mechanical and histological results
