Perioperative management of antithrombotic medication in head and neck reconstruction—a retrospective analysis of 137 patients

PurposeVarious protocols exist to prevent thrombosis after free flap surgery in the head and neck. This study reviews the outcome and incidence of perioperative complications in patients undergoing head and neck reconstruction, simply using subcutaneous low-molecular-weight heparin.Materials and methodsA total of 137 free tissue transfers performed between 2007 and 2010 were reviewed. All patients received a general thrombosis prophylaxis with subcutaneous low-molecular-weight enoxaparin. No aspirin, dextran, or additional antithrombotic medication was administered.ResultsOverall flap survival was 97.1%. A total of 3 complete and 1 partial flap loss occurred, all due to venous thrombosis. Five cases of venous congestion were successfully revised.ConclusionThe free flap survival rate using simple subcutaneous heparin seems to be equivalent to other management regimens. Therefore, we suggest that no additional antithrombotic treatment is needed for patients who undergo head and neck reconstruction with free tissue transfer.
