ObjectiveTo survey practices concerning the use of anticoagulants and antiplatelets in microvascular free-flap reconstruction following oncological surgery of the head and neck. MethodsA survey of practices was carried out between September 2022 and March 2023. An online questionnaire was sent to members of the French GETTEC Head-and-Neck Tumor Study Group in all French centers practicing head-and-neck cancer surgery with reconstruction using microvascular free-flaps. The questionnaire asked surgeons about their practices regarding the use of intra- and postoperative anticoagulants and antiplatelets, preoperative management of comorbidities, and prevention of postoperative complications. ResultsSixty-one percent of the 38 respondents (23/38) used intraoperative intravenous heparin injection, associated to flap irrigation with heparin for 76% of surgeons (29/38) and/or a heparin solution bath for 37% (14/38). Postoperative anticoagulation was used by 95% of surgeons (36/38), and antiplatelets by 40% (15/38). Postoperatively, 40% (15/38) carried out monitoring using an implantable micro-Doppler probe, associated to analysis of clinical characteristics of the flap. ConclusionReconstructive surgery using microvascular free-flaps involves numerous factors that can influence success. Prospective studies, particularly concerning the management of anticoagulants, could enable a national consensus on methods for free-flap reconstruction.
