Popis: To compare the average number of culprit arteries per patient, clinical success rate, and hemoptysis-free survival rate between hemoptysis patients with multidetector computed tomography (MDCT) angiography prior to bronchial artery embolization (BAE) and those without preprocedural MDCT angiography This retrospective study was approved by the institutional review board with waiver of patient informed consent. From September 2012 to March 2017, 157 consecutive hemoptysis patients had been undergoing BAE. Among them, 106 patients received preprocedural MDCT angiography (MDCT group), while 51 patients did not receive preprocedural MDCT angiography (control group). The average number of culprit arteries per patient, clinical success rate, and hemoptysis-free survival rate were compared between the two groups. The average number of culprit ectopic bronchial arteries and that of non-bronchial systemic arteries originating from the subclavian and internal mammary arteries per patient in the MDCT group were both significantly higher than those in the control group (0.15 ± 0.51 vs 0.04 ± 0.20, p = 0.022, and 0.17 ± 0.56 vs 0.08 ± 0.39, p = 0.040, respectively). The clinical success rate of BAE with preprocedural MDCT angiography tended to be higher than that without MDCT angiography (97.2 vs 88.2%, p = 0.057). Importantly, patients in the MDCT group had a significantly higher hemoptysis-free early survival rate compared to those in the control group (96.1 vs 86.7%, p = 0.031). Preprocedural MDCT angiography helps detect culprit ectopic bronchial arteries and non-bronchial systemic arteries originating from subclavian and internal mammary arteries during BAE, and can improve the hemoptysis-free early survival rate, which could be recommended as a regular examination prior to BAE in patients with hemoptysis. • Preprocedural MDCT angiography helps detect culprit ectopic bronchial arteries and NBSAs originating from subclavian and internal mammary arteries during BAE. • Conducting MDCT angiography prior to BAE can improve hemoptysis-free early survival rate in hemoptysis patients.
