A Stepwise Embolization Strategy for a Bronchial Arterial Aneurysm: Proximal Coil and Distal Glue with the Optional Use of a Microballoon Occlusion System

Purpose This study aimed to demonstrate a transcatheter embolization strategy for bronchial artery aneurysms (BAAs) using coils for the proximal lesion and glue (n-butyl-2-cyanoacrylate [NBCA]) embolization for the distal lesion with or without the use of a microballoon occlusion catheter.
