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.
Materials And Methods:
Five patients with BAAs presenting with hemoptysis were enrolled in this study. A bronchial angiogram indicated a mediastinal BAA near the orifice, accompanied by dilated distal branches with or without intrapulmonary BAA. A stepwise procedure was performed. First, the intrapulmonary branches were embolized with glue, with or without the use of a microballoon catheter depending upon the anatomical and local flow hemodynamic conditions. Second, the mediastinal BAA was tightly packed with detachable coils.
Results:
Glue embolization of intrapulmonary abnormal branches successfully controlled hemoptysis in all patients; microballoon catheters were used in five of the 10 arteries. The volume embolization ratio of coils within the mediastinal BAA ranged from 28 to 59%, and neither coil compaction nor signs of recanalization were observed during follow-up.
Conclusion:
The stepwise embolization procedure with the sequential use of glue (with or without a microballoon occlusion system) and detachable coils may represent a possible endovascular strategy for the treatment of complex BAAs.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
