In an attempt to overcome some of the difficulties inherent in vascular anastomosis using standard suture methods, we have developed a technique that allows for rapid non-suture anastomosis of blood vessels. The technique has been used in over 400 anastomoses, including interposition vein grafts in rat, rabbit and dog vessels ranging in size from 0.7 mm to 3 mm in diameter. Animals have been followed for over 1 year ostoperatively with serial angiography and histological evaluation including scanning electron microscopy. Stress studies have compared the biomechanical properties of both non-suture and suture anastomosis. The overall patency rate in non-suture end-to-end anastomoses using an interposition vein graft was 85% at 1 year follow up. Histological evaluation revealed a healing pattern that was temporally similar to that of the suture technique. Stress tests revealed no significant difference between suture and non-suture technique. These studies reveal that the non-suture technique compares favourably with the suture technique, and demonstrate the feasibility of applying this technique to man.
