Purpose: Report a case of transcatheteral embolization of a Bronchial Artery Aneurysm (BAA) using Onyx. Case report: A 60 years-old man was hospidalized because mediastinum hematoma related to BAA. Left transsucclavian approach was conducted and the microcatheter was used to reach the BAA. Because vessel caliper and tortuosity aneurism packing was not possible, so why Onyx 34 was released as close as possible to the aneurysmatic sac with “plug and push” technique. The clinical condition of the patient immediatly improved and the 1-month CTA confirmed the complete exclusion of BAA; patient did not claim any particular disturbs after 7-month follow-up. Conclusions: Embolization of BAA using Onyx 34 is feasible and viable.
