Bronchial Artery Aneurysm with Associated Bronchial Artery to Pulmonary Artery Fistula: Treatment by Embolization.

Bronchial artery aneurysm (BAA) is a rare vascular phenomenon. This review highlights a case of a BAA that was complicated by the presence of a bronchial artery to pulmonary artery (BA-PA) fistula, consequently presenting a unique challenge to management. BAAs have a strongly reported risk of rupture resulting in life-threatening hemoptysis. Embolization has thus become routine for the management such severe cases. The management of incidentally found anomalies is less obvious, but prophylactic embolization is a generally accepted practice. In this report, we review some of the risks and benefits associated with BAA embolization with specific consideration of the challenges in cases of co-existing BA-PA fistula.
