(a) Coronal CTA MIP demonstrates hypertrophic bronchial artery with tortuous course originating at 9:00 from the convexity of the aortic arch (white arrows); (b) DSA performed with Simmons 1 catheter at the level of the ostium of the bronchial artery confirms the presence of the hypertrophic vessel (black arrow) with a small tributary branch of the right upper lobe (arrow head); (c) single-shot fluoroscopy after embolization shows the presence of the microcatheter at the level of the proximal portion of the bronchial artery, with a Squid 12 cast completely occupying the main trunk (white arrows); (d) post-procedure DSA control demonstrates complete exclusion of the treated vessel (asterisk) with patency of the small branch for the right pulmonary upper lobe (white arrow).
