Description
Summary:Purpose To investigate airway development and airway resistance by computed tomographic three-dimensional (3D) reconstruction of the bronchial tree in patients with adolescent idiopathic scoliosis (AIS). We evaluated factors predicting postoperative respiratory complications to provide timely treatment, prevent complications, and improve operative and anesthetic safety. Methods From August 2015 to August 2017, 53 AIS patients with a mean age of 15.4 years (range 10–20 years) were included in this study. Scoliotic parameters on radiographs were analyzed. Airway resistance was obtained by pulmonary function testing. All patients’ pulmonary bronchial trees were 3D-reconstructed via chest thin layer computed tomography to explore the correlation between the spinal–thoracic deformity parameters and airway resistance. Results Correlations between scoliotic parameters and airway development parameters were not statistically significant ( P  > 0.05). The scoliotic parameters such as Cobb angle, apical vertebral translation, rotation angle to sagittal plane, rotation angle to middle line, and apical vertebral body–rib ratio (AVB-R) were positively correlated with tracheal bifurcation angle ( R 2 : 0.429, 0.374, 0.430, 0.504, and 0.414, respectively; P
