After head and neck reconstruction, flap congestion due to IJVT may lead to flap necrosis, and early diagnosis and treatment should be considered. We experienced a case of disappearance of IJVT in which edoxaban was administered after free-flap reconstruction, and the entire flap survived. Edoxaban has few bleeding complications and was useful as a single drug approach for IJVT after head and neck reconstruction.Keywords: Internal jugular vein thrombosis, Head and Neck reconstruction, Edoxaban
