Exposure of a Microvascular Anastomotic Coupler in Head and Neck Reconstruction: A Case Report

Objective: We present a case of exposure of a microvascular anastomotic coupler. Methods: We performed venous anastomoses using microvascular anastomotic couplers in head and neck reconstruction. Results: A microvascular anastomotic coupler was exposed in the seventh month postoperation, and an anastomosed vein was disrupted. Conclusions: Although the usefulness of the microvascular anastomotic coupler in microsurgical flap reconstruction is not in doubt, as described previously, we believe that it is necessary to remember that use of a microvascular anastomotic coupler involves potential risks of exposure and anastomosed vessel disruption.
