Enhancing microvascular anastomoses with the Synovis Coupler device: A retrospective analysis of management of vascular diameter discrepancies.

ABSTRACT:

Background and introduction

Microvascular surgery enables complex tissue repairs with free flaps. The Synovis Coupler has streamlined venous anastomoses, improving speed and precision. However, size discrepancies between donor and recipient vessels continue to cause postoperative complications. This study presents our experience in managing caliber discrepancies, optimizing venous flow, reducing thrombosis risk, and improving free flap survival.

Material and methods

This retrospective observational study analyzed data from patients undergoing free flap reconstruction between January 2018 and January 2024. A total of 84 microvascular free tissue transfers and 86 venous anastomoses were performed using a mechanical coupler system.

Results

Eighty-six venous anastomoses w
