Objective: To estimate the value of multidetector computed tomography angiography (MDCTA) and image analysis before bronchial artery embolization (BAE) in the treatment of hemoptysis. Methods: A total of 165 patients with hemoptysis who underwent BAE at the Department of Interventional Radiology of Xiangyang Central Hospital from August 2017 to June 2021 were retrospectively analyzed and divided into two groups: MDCTA group [with preoperative MDCTA, 88 patients,63 males and 25 females,aged 23 to 87(62.6±12.3) years] and control group [77 patients, 52 males and 25 females, aged 26 to 83 (59.8±12.7) years]. The number of bronchial arteries and non-bronchial systemic arteries, and clinical success rate were compared between the two groups. Comparisons within groups were performed using the t-test or nonparametric paired Wilcoxon test for quantitative data with paired design, while comparisons between groups were performed using the t-test for the mean of two independent samples or the nonparametric Mann-Whitney U test for independent samples and comparisons between groups were performed using the chi-square test. Results: The number of orthotopic and ectopic bronchial arteries found in BAE procedure in the MDCTA group was significantly higher than that in the control group [1.77±0.72 vs. 1.42±0.82, P=0.003; 0 (0, 0) vs. 0 (0, 0), P=0.033, respectively]; in the MDCTA group, the numbers of orthotopic and ectopic bronchial arteries found by MDCTA were significantly higher than those found in BAE procedure [2.22±0.63 vs. 1.77±0.72, P<0.001; 0 (0, 0) vs. 0 (0, 0), P=0.005, respectively]. The number of non-intercostal arteries found by MDCTA in the MDCTA group was significantly higher than that in the control group [0 (0, 0) vs. 0 (0, 0), P=0.038]. Hemostatic success was significantly higher in the MDCTA group than that in the control group (88.6% vs. 68.8%, P=0.002). Conclusions: MDCTA and image analysis help to detect more bronchial arteries and improve the hemostatic success rate before bronchial artery embolization in the treatment of hemoptysis.
