Abstract
Low energy Nd-YAG laser was utilized to make vascular welding with contact method. After success and good patency for vascular welding in canine experience, sixty three patients with 4 ischemic heart disease, 2 coarctation complex, 39 peripheral occlussive disease and 18 chronic renal failure were received laser vascular welding. these weldings successed in all cases except one and patency rate was excellent. The anastomotic sites of the aorta in infants were growable. Late patency rate was also excellent because of 77% seven years later.
