Bronchial artery charateristics and patient outcome in patients with acute hemoptysis treated using dual embo-agents
Main Article Content
Abstract
SUMMARY
Objectives: This study was carried out to describe angiographic charateristics and patient outcome in patients with acute hemoptysis treated using dual embo-agents.
Methods: 28 patients with acute hemoptysis were included in this study. All abnormal vessels were occluded using microsphere
then re-enforced with N-butyl cyanoacrylate (NBCA). Patients were followed-up one year from procedure date.
Results: Technical success rate accounted for 96.4%. Almost all patients presented with bronchial artery dilatation while 46% of patients had abnormal feeding vessels arising from subclavian artery, 39% from intercostal arteries. Postprocedural complications
included chest pain (4 cases, 14.3%), infection (1 patient, 3.6%), unexpected vessel occlusion (1 case, 3.6%) and bronchial artery dissection (1 subject, 3.6%). Recurrent rate calculated in one year of following up was 7.14%.
Conclusion: Major angiographic abnormalities were dilatation of the bronchial artery to lung lesions and its colaterals. Dual-material embolization is an effective treatment method with significantly high rate of technial and clinical success.
