Synchronous microsurgical anastomosis in complex replantation surgery

Abstract

We conducted a retrospective case control study of digital replantations in 16 patients from September 2015 to January 2017. Half of the patients were treated by a synchronous microsurgical technique and the other half underwent conventional micro-anastomoses. The total time for anastomoses, total operation time and survival of digits were the major endpoints in this study. The number of digits replanted and the anastomosis method had significant effects on total anastomosis time. The mean anastomosis time for each digit was 46 min and 70 min in the synchronous and conventional groups, respectively, a 34% reduction in anastomosis time in the synchronous group when compared with the conventional group. Patency rates were 87% (13/15) of all the digits replanted in each group. Level of evidence: IV
