Intra-arterial embolization of juvenile nasopharyngeal angiofibroma (JNA) prior to surgical resection is the preferred approach minimize blood loss during tumor. However, presence external carotid artery-internal artery (ECA-ICA) anastomoses may hinder complete tumor due associated risk for embolic complications. Here, we evaluate use a balloon-assisted (BAE) technique in treatment JNA. We conducted retrospective review JNA patients who underwent with injection Onyx single session between 2013-2018. All cases displayed arterial supply from ECA and ICA circulations on 2-D catheter angiograms. Procedural outcome data were analyzed. Results are given as mean±standard deviation (range). Among 9 JNA, all males mean age was 14.1±6.3 years (range, 9-29 years). The volume 84.4±12.4% 60-100%) 89% ≥80% achieved. There no embolization-related complications reported. During there low average 722±651.5 mL 50-2,000 mL) procedure time 282.6±85.4 mins 151-403 mins). In this series, BAE showed be safe effective achieve successful while avoiding effectively reducing resection.
