Abstract:
Objective:To investigate the high-resolution CT features and risk factors of secondary bronchiolitis obliterans (BO) in children with adenovirus pneumonia.Methods:In this study, a case-control study method was adopted, and 44 children with BO secondary to adenovirus pneumonia in Dongguan Children′s Hospital Affiliated to Guangdong Medical University from January 2015 to October 2020 were selected as the observation group, and 45 children with simple adenovirus pneumonia during the same period were selected as the control group. The differences in the chest high-resolution CT imaging characteristics of the two groups of children were compared. The risk factors of secondary BO in children with adenovirus pneumonia were analyzed by single factor and multiple factor logistic regression.Results:In the lung CT examination of children in the observation group, the detection rates of mosaic perfusion sign, bronchial wall thickening, bronchiectasis, lung consolidation and clear lung were significantly higher than those in the control group, and the difference was statistically significant (all P<0.05); Logistic regression model showed that prolonged heat course, high heat peak, mechanical ventilation treatment and prolonged mechanical ventilation time were independent risk factors of secondary BO children with adenovirus pneumonia (all P<0.05). Conclusions:Children with BO secondary to adenovirus pneumonia have typical high-resolution CT features, which is of high practical value for clinical diagnosis. Prolonged heat course, high heat peak, mechanical ventilation treatment and prolonged mechanical ventilation were independent risk factors of secondary BO in children with adenovirus pneumonia.
