Abstract

A comparative experimental study was performed in 105 Wistar rats for micro-arterial anastomosis between CO₂ laser welding and traditional hand suture. The advantages of laser welding of small arteries were: (1) It's easier, more accurate, and faster. (2) More rapid, smooth healing and less inflammatory reaction. (3) The diameter of anastomotic stoma increased corresponding with the growth of the animals. Compared with hand suture, the tensile strength of anastomotic stoma with laser welding was weaker during the early postoperative period, and there was a certain percentage of aneurysm formation at the stoma.
