| アブストラクト | Background The most serious complication of bronchial artery embolization (BAE) for hemoptysis is spinal cord infarction. However, because it is rare, previous reports from single institutions have been insufficient to determine the actual prevalence of spinal cord infarction after BAE. Purpose To investigate the actual prevalence of spinal cord infarction as a complication of BAE using a nationally representative inpatient database. Materials and Methods This retrospective study was performed using data from the Japanese Diagnosis Procedure Combination database between July 2010 and March 2018. The authors identified patients who were diagnosed with hemoptysis and underwent BAE during hospitalization. The overall prevalence of spinal cord infarction after BAE was determined. The authors also compared the prevalence of spinal cord infarction using the Fisher exact test according to the embolic agent used for BAE: coils, gelatin sponge (GS) particles, and N-butyl-2-cyanoacrylate (NBCA). Results During the study period, 8563 patients (mean age +/- standard deviation, 68 years +/- 13; 5103 men) met the inclusion criteria. Among these 8563 patients, 1577 (18%), 6561 (77%), and 425 (5%) underwent BAE with coils, GS particles, and NBCA, respectively. The overall prevalence of spinal cord infarction as a complication of BAE was 0.19% (16 of 8563 patients). The prevalence of spinal cord infarction after BAE with coils, GS particles, and NBCA was 0.06% (one of 1577 patients), 0.18% (12 of 6561 patients), and 0.71% (three of 425 patients), respectively (P = .04). Conclusion With use of a nationwide real-world inpatient database, the results of this study demonstrated that the actual prevalence of spinal cord infarction as a complication of bronchial artery embolization (BAE) for hemoptysis was 0.19%. Patients who underwent BAE with coils had a lower prevalence of spinal cord infarction than patients who underwent BAE with gelatin sponge particles or N-butyl-2-cyanoacrylate. (c) RSNA, 2021. |
