AIM: This study assesses the safety and efficacy of particle embolization during bronchial artery embolization (BAE) in patients with shunts between bronchial and non-bronchial systemic arteries and the pulmonary artery.
METHODS: In this retrospective, single-center study, we analyzed 312 BAE procedures performed from June 2020 to April 2023. The patient cohort had shunts between bronchial and non-bronchial systemic arteries and the pulmonary artery. We meticulously collected and examined comprehensive data, including clinical characteristics, computed tomography (CT) imaging, and embolization procedural details.
RESULTS: Vascular shunts were identified in 49 patients. The etiologies of hemoptysis included post-TB sequelae (42.8%), bronchiectasis (26.5%), active TB (12.2%), aspergilloma (8.1%), bacterial pneumonia (4.1%), lung cancer (4.1%), and non-tuberculous mycobacterial infection (2%). The technical success rate of the procedures was 98%, with 149 out of 152 identified vessels successfully embolized. All patients experienced cessation or significant reduction of hemoptysis within 24 hours following the procedure. The clinical success rates were 97.9% at one month, 93.9% at six months, and 89.8% at one year. No shunt-related complications were detected.
CONCLUSION: BAE with particle embolization is a safe and effective treatment for hemoptysis, particularly in cases with complex shunts between bronchial and non-bronchial systemic arteries and the pulmonary artery.
