Utilization of microvascular couplers in salvage arterial anastomosis in head and neck free flap surgery: Case series and literature review

Head Neck. 2020 Aug;42(8):E1-E7. doi: 10.1002/hed.26139. Epub 2020 Mar 20.

Abstract

Background: In microvascular reconstruction of ablative oncologic defects, coupler devices have traditionally been used for venous anastomosis, whereas the arterial anastomosis is hand-sewn. In the setting of repeated intraoperative arterial anastomotic thrombosis, a coupler device may be of use in reducing the risk of rethrombosis.

Methods: Two patients were seen with advanced stage head and neck cancer and underwent oncologic resection. During microvascular reconstruction, a clot at the arterial anastomosis was encountered in both cases.

Results: After starting therapeutic anticoagulation and attempting unsuccessful suture reanastomosis, coupler devices were used for arterial anastomosis, resulting in viable free-tissue transfer.

Conclusions: Although traditionally used for venous anastomosis, coupler devices may serve a purpose in the salvage setting when facing repeated intraoperative arterial thrombosis.

Keywords: free flap reconstruction; microvascular anastomosis; thrombosis; vessel couplers.
