Abstract
Laser has been widely utilized in the field of cardiovascular surgery. Since 1980 we have employed CO2 or Argon laser for creating transmyocardial revascularization and making vascular anastomosis as well as performing laser angioplasty. In this study-vascular anastomosis by laser was investigated experimentally and clinically. Subsequently, optimal conditions for vascular ananstomosis were 20-40mW in output and 6-12 sec/mm in irradiation time. Based on the excellent experimental studies laser was clinically employed for 108 patients with intermittent claudication and anginal attack as well as tissue ischemia. Anastomotic sites were located in the femoral-, and the tibial arteries, the radial- and the brachial arteries as well as the coronary arteries. The longest follow-up period is now 5 years 9 months after laser surgery. They are doing well, except for 1 case who had tiny hematoma after body exercise. Thus, an availability of vascular anastomosis by laser could be recognized.
