Coupling the venous anastomosis: Safe and simple

Abstract

Varous anastomotic coupling systems have been developed aiming to facilitate microvascular anastomoses. Of these only the 3M Precise Microvascular Anastomotic System (MAS) has recently gained increasing popularity. However, clinical studies on the use of the MAS are sparse. We report our clinical experience with the MAS in a two-centre study between 1991 and 1996. Of the 96 MAS coupling rings used, 50 were accessible for final analysis, and a 100% patency rate was obtained. The main indication is venous end-to-end anastomosis in vessels of minimal discrepancy. In selected cases in head and neck surgery even end-to-side venous anastomoses appear to be feasible. Although it is not universally applicable for microvascular anastomoses, we conclude that, if appropriate, the MAS coupling device leads to a reliable venous anastomosis in a greatly reduced operating time of less than 4 minutes. © 1997 Wiley-Liss, Inc.
