Anomalous Origin of Bronchial Arteries: Potential Pitfall of Embolotherapy for Hemoptysis

Anomalous bronchial artery originating from the right coronary artery in a patient with angina (2009: 4b)

“…The majority of BAAOs originate from the aortic arch. These BAAOs may also originate from the internal mammary artery, thyrocervical trunk, subclavian artery, inferior phrenic artery, left gastric artery, or the descending thoracic aorta [2][3][4][5][6][7]. To our knowledge, the bronchial artery arising from the coronary artery has not been reported.…”

“…BAAOs are defined as bronchial arteries that originate outside the descending aorta between T4 and T6 vertebrae at the level of the major bronchi: the reported prevalence ranges from 16.7% to 30% [2]. These anomalous bronchial arteries may arise from the aortic arch, internal mammary artery, thyrocervical trunk, subclavian artery, inferior phrenic artery, left gastric artery, or the descending thoracic aorta [2][3][4][5][6][7]. In this report, we present a case of BAAO originating from the right coronary artery causing a coronary steal phenomenon in a patient with a prior history of haemoptysis.…”

Hemothorax Complicating Bronchial Artery Aneurysm

“…Embolization offers an attractive, minimally invasive approach that can be performed in emergent settings (1). Recognizing variations in bronchial arterial anatomy is critical under any circumstances and, in this regard, it was intriguing that, as in our case, an origin arose from the underside of the arch (5,11). Although most reports describe the use of coils, biological glue has also been successfully used (6).…”

A rare cadaveric finding of ectopic origin of a bronchial artery: surgical and imaging consequences

“…Therefore, several other BA anastomoses (e.g. the coronary artery) should be sought prior to the administration of embolic agents, in order to prevent potentially catastrophic complications [8,10].…”
