Abstract：Objective: To summarize the MSCT findings of PAS and evaluate the value of MSCT in preoperative evaluation of PAS. Methods: The clinical and imaging data of 14 patients with PAS were analyzed retrospectively. Bronchial morphology and stenosis were classified. Results: Fourteen patients were all complete PAS. The diagnostic rate of MSCT for PAS was 100%, including 3 cases of type ⅠA, 6 cases of type ⅡA, 5 cases of type ⅡB. There were 6 cases of mild stenosis, 7 cases of severe stenosis, 6 cases of short segment stenosis, and 7 cases of long segment stenosis. Seven of the 14 patients had other congenital cardiovascular abnormalities. Conclusion: MSCT plays an important role in the early diagnosis of PAS. At the same time, MSCT can clearly diagnose the PAS related complications and display the extent and scope of tracheal stenosis. It has a high application value for preoperative evaluation of PAS.
