Pre-operative embolization of naso-pharyngeal angiofibromas

58 patients with a juvenile nasopharyngeal angiofibroma have been treated by a combined neuroradiological-surgical method. In the cases with smaller tumor extension, fed only by the external carotid arteries or with only slight participation of the internal carotid arteries, the external carotid arteries alone have been embolized using particles. In the cases with marked participation of the internal carotid arteries vessels were also embolized. In the first group there have been no complications and no recurrences. In the latter (31 cases) there have been three temporary minor complications and 11 recurrences. (orig.)
