OBJECTIVES: To identify the prevalence of non-bronchial systemic culprit arteries and their relationship to bleeding lobes in patients with hemoptysis with bronchiectasis and chronic pulmonary infection who underwent de novo bronchial artery embolization (BAE).
METHODS: Data of 83 consecutive patients with bronchiectasis and chronic pulmonary infection (non-tuberculous mycobacteriosis, aspergillosis, and tuberculosis) who underwent de novo BAE between January 2019 and December 2020 were retrospectively reviewed. The prevalence of culprit arteries was investigated.
RESULTS: Fifty-five patients (66%) had 172 non-bronchial systemic culprit arteries. The bleeding lobes were the right upper, right middle, right lower, left upper, and left lower lobes in 14 (17%), 20 (24%), 7 (8%), 31 (37%), and 11 (13%) patients, respectively. The internal thoracic (49%; n = 41), intercostal (28%; n = 23), and inferior phrenic (28%; n = 23) arteries were the top three non-bronchial systemic culprit arteries, which were involved in all five types of bleeding lobes. The costocervical trunk and thoracoacromial and lateral thoracic arteries were predominant in patients with upper lobe bleeding. Ligament arteries were predominant in patients with left lower lobe bleeding.
CONCLUSIONS: These findings will better ensure the identification of non-bronchial systemic culprit arteries in patients with hemoptysis with bronchiectasis and chronic pulmonary infection. All systemic arteries, especially those which are adjacent to the lung lesions, should be evaluated carefully using MDCT; the internal thoracic, intercostal, and inferior phrenic arteries should be proactively assessed using angiography.
KEY POINTS: • Non-bronchial systemic culprit arteries were identified in 66% of patients with hemoptysis with bronchiectasis and chronic pulmonary infection who underwent de novo bronchial artery embolization. • The internal thoracic (49%), intercostal (28%), and inferior phrenic (28%) arteries were the top three arteries, which were involved in all five types of bleeding lobes. • The costocervical trunk and thoracoacromial and lateral thoracic arteries were prominent in patients with upper lobe bleeding, and the ligament artery was prominent in patients with left lower lobe bleeding.
