Objective To evaluate the efficacy of bronchial artery embolization in the treatment of massive hemoptysis. Methods A retrospective analysis was conducted on the clinical data and treatment of 161 patients who underwent bronchial artery embolization （BAE） for massive hemoptysis at Pingliang Second People’s Hospital

Guiyang Guizhou International Hospital

and the Second Clinical Medical College of North Sichuan Medical College from January 2021 to June 2022

and the effectiveness of BAE was analyzed. Results Of the 161 patients

98 were male and 63 were female

with an age range of 23 to 89 years and an average age of 56.4 years. There were a total of 263 embolized vessels

including 172 bronchial arteries （bronchialartery

BA）

14 ectopic bronchial arteries and 77 non-bronchial somatic arteries （such as intercostal artery

internal thoracic artery

lateral thoracic artery

nail cervical trunk

costal cervical trunk

proper esophageal artery

etc.）. All patients completed embolization

hemoptysis disappeared or alleviated after embolization

and the total effective rate was 100%. Within 3 months after embolization

there were 16 cases of recurrent massive hemoptysis

resulting in a recurrence rate of 9.94%. Five cases (3.11%) experienced severe adverse reactions

with spinal cord injury being the main complication. Conclusion BAE was an effective treatment for massive hemoptysis caused by various reasons

with a low incidence of complications. It could be utilized as a clinical approach for managing massive hemoptysis.
