Abstract
In vascular surgery, there is a great problem to keep high patency rate after reconstructive surgery especially for small-caliber vessels. For resolving of this problem, laser was applied to make vascular anastomosis with few stay sutures. Optimal conditions of vascular anastomosis by lasing were 20~40mW in output and 6~12sec/mm in irradiation time. Histological examination revealed good healing at the sites of anastomosis by laser. And adequate in of the anastomotic sites by laser was also confirmed. On the basis of excellent experimental studies, laser was employed to make vascular anastomosis in 91 patients with intermittent claudication and anginal pain and renal failure. The first successful clinical application was carried out in 44year-old female patient with renal failure on 21st February 1985 in the world. Coronary artery bypass surgery was also performed clinically by using low output Co2 laser. All patients are now doing well without any complications throughout the laser. The longest survivor has been passed 4years 9months after laser surgery. Laser application in this field was useful and inevitable to make vascular anastomosis especially for small-caliber vessels.
