Pre-operative embolization of juvenile nasopharyngeal angiofibromas.
Pre-operative embolization of juvenile nasopharyngeal angiofibroma was performed in 15 patients. The lesion was supplied by the internal carotid arteries (8 cases), by the internal maxillary artery (15 cases), the accessory meningeal artery (10 cases) and the ascending pharyngeal artery (10 cases). Superselective embolization of the external carotid artery feeders was performed with Ivalon particles, without neurological complications. Good control of per-operative blood loss was noted in 13 out of 15 cases, 2 patients presenting severe per-operative venous bleeding. Recurrence was noted in only one patient, which could be controlled by reembolization.
