In the rabbit, posterior facial vein segments were grafted to the femoral arteries using either conventional suture technique or a mechanical absorbable pinned‐ring device. The purpose of this study was to compare patency rates and anastomotic times for the two different methods. The anastomoses were evaluated macroscopically and using light and scanning electron microscopy. The grafts anastomosed with the absorbable rings exhibited 100% patency, while only 83% of the sutured grafts were patent. The mean anastomotic time using the mechanical pinned‐ring device was 18.1 min (range 9.8–30 min). The conventionally sutured anastomoses were completed in a mean time of 60 min (range 50–75 min). The experiment has confirmed that the absorbable pinned‐ring device provides a safe and fast way to perform microvascular anastomosis. © 1999 Wiley‐Liss, Inc. MICROSURGERY 19:128–134 1999
