 Organized hematoma is a rare, non-neoplastic, and hemorrhage-prone condition that requires attention due to the risk of intraoperative bleeding. Preoperative embolization was performed to ensure intraoperative hemorrhage control. Here, we report a case of preoperative embolization of an organized hematoma using a low-concentration of n-butyl-2-cyanoacrylate(NBCA). An 80-year-old male presented with a 2-month history of repeated nasal bleeding and nasal obstruction. Diagnostic imaging revealed a mass measuring 3.7 cm in the right maxillary sinus with thinning of the surrounding bone. This was diagnosed as an organized hematoma with a biopsy. As a preoperative treatment, embolization of the main feeding artery was performed through the external carotid artery, using a low concentration of NBCA(5%). When the NBCA cast had reached the organized hematoma, as observed on plain CT, endoscopic sinus surgery was performed, and the organized hematoma was resected without significant bleeding. Preoperative embolization of the organized hematoma with low-concentration NBCA was useful to prevent heavy intraoperative bleeding.
