RAPID ARTERIAL ANASTOMOSIS WITH TITANIUM CLIPS

BACKGROUND: The obvious advantages of rapid arterial anastomoses have prompted the continuing search for more rapid anastomotic techniques t o complement the standard sutured anastomosis. Nonpenetrating, arcuate -legged titanium vascular closure staple (VCS) clips were initially de veloped for microvascular anastonaoses. The purpose of this study was to compare VCS clips with sutured arterial end-to-end anastomosis in l arger vessels. METHODS: In 6 pigs, transacted iliac arteries were rean astomosed with VCS clips on one side and continuous 6-0 polypropylene suture on the other. RESULTS: The reconstruction time was 8.4 +/- 5.2 minutes for clip closure and 12.0 +/- 6.6 minutes for suture closure ( P = 0.033). All vessels were patent half an hour after completing the anastomoses with tao signs of early thrombosis. CONCLUSIONS: Arterial end-to-end anastomosis can be performed more rapidly with VCS clips th an continuous sutures, and are potentially useful in situations where the clamp time of the vessel is critical.
