Identifying feeding artery during preoperative embolization of juvenile nasopharyngeal angiofibroma

Abstract

Treatment of choice and standard of care is surgical resection of the tumor. Nasopharyngeal angiofibromas receive an abundant blood supply mainly from the external carotid branches and partly from the internal carotid artery branches. Many patients are treated with preoperative embolization to minimize the risk of intraoperative hemorrhage and related complications . This retrospective study, we obtained analysis of the medical and imaging records of 11 patients with pathologically proven juvenile nasopharyngeal angiofibroma. Who we performed preoperative endovascular embolization between January 2019 until Desember 202 in Wahidin Sudirohusodo Hospital, Makassar, Indonesia. The procedure was carried out using a cathlab monoplane Philips. A total 11 patients (only 1 female) with juvenile nasopharynx angiofibroma underwent endovascular embolization from 2019-2021 in Wahidin Sudirohusodo Hospital Makassar. Arteriography examination in patients with angiofibroma tumors revealed that the feeding arteries originate from the internal maxillary artery, ascending pharyngeal artery, fascial artery, middle meningeal artery and branches of the internal carotid artery. Identifying the feeding artery before embolization is very important to facilitate the embolization process
