Abstract
In an experimental study, a new mechanical device for microvascular an astomosis was compared with suture anastomosis. In 14 rabbits, seven e nd-to-end and seven end-to-side anastomoses of the jugular vein to int erpositional vein grafts were done with a ring-pin device and by the c onventional suture method. There was no significant difference between the patency rates of mechanical and suture anastomoses. The completio n of mechanical anastomoses took one-third the time required for sutur e anastomoses. After 10 days, histologic and scanning electron microsc opic examination revealed an uneventful reparative process at the anas tomotic site with media atrophy and a continuous endothelial layer. At 4 weeks, occasional foreign body giant cells were seen between the po lyethylene rings and surrounding connective tissue. The study confirms that the ring-pin device is safe and provides a faster way to do micr ovascular anastomoses than by suturing.
