Abstract

　　Juvenile nasopharyngeal angiofibroma（JNA）is a rare and benign disease, and is primarily diagnosed in male adolescents. It is a highly vascularized slow-growing tumor, but it is locally invasive and destructive to the surrounding normal tissue. Originating in the margin of the sphenopalatine foramen, these tumors extend into the pterygopalatine fossa, paranasal sinus, and nasal cavity, leading to such symptoms as pain, unilateral nasal obstruction, and epistaxis. Preoperative transcatheter arterial embolization（TAE）of tumor-supplying vessels has been recommended in the literature to decrease intraoperative blood loss.
We herein report a patient with JNA on whom we performed preoperative TAE. An 11-year-old male patient presented with nasal bleeding. Contrast-enhanced CT and MRI revealed a JNA in the patient’s left nasal cavity. The patient underwent preoperative TAE on the day of the surgery. The blood loss during the surgery was 200ml, and the surgery was performed successfully. Despite several risks, preoperative TAE is an effective means for reducing intraoperative blood loss.
