Abstract
We report the first case of a juvenile nasal angiofibroma (JNA) fed by multiple arteries from the internal carotid artery (ICA), removed without complications by temporarily blocking the ICA with two balloons. An early adolescent with JNA underwent preoperative embolisation of feeding arteries arising from the external carotid artery (ECA) (University of Pittsburgh Medical Centre classification IV). Endoscopic resection was attempted once but discontinued due to massive bleeding (7000 mL). 17 months later, the JNA had grown to fill both nasal cavities. Repeated preoperative embolisation of the feeders from the ECA was performed, followed by surgery combined with endoscopic and external incision. Intraoperatively, two balloons were inserted into the right ICA, which were inflated at the proximal and distal sites of the feeder vessels to cut-off blood flow to the tumour. The tumour was almost completely resected with 6270 mL of blood loss and no postoperative neurological deterioration.
