An Unexpected Cause of Catastrophic Bleeding During Juvenile Nasopahryngeal Angiofibroma Excision.

We describe the first case of juvenile nasopharyngeal angiofibroma receiving blood supply from caroticotympanic artery which resulted in catastrophic bleeding intraoperatively. The patient was an 12-year-old boy with a Radkowski stage 3B JNA. We utilized preoperative embolization of feeders from external carotid artery though the surgeon failed to excise the tumor completely due to uncontrollable bleeding from the tumor. On retrospective analysis of angiography only the culprit feeder found. Tumor was excised in the second surgery conducted a week later. Although selective embolization of ICA branches are described in literature the data are sparse and so is the management of such cases.
