Abstract:
Objective To explore the value of low-dose CT in the diagnosis of congenital heart disease(CHD)with tracheal stenosis (CTS)in infants.Methods Data of low-dose CT and echocardiography in 18 cases of CHD with CTS were analyzed retrospectively, and compared with surgical findings.Results 18 cases of CST were comfirmed by surgical operation.The diagnostic accuracy of low-dose CT was 100%,and there was no statistical difference in the assessment of the range and degree in tracheal stenosis(P=0.76>0.05, P=0.767>0.05).42 cardiac anomalies were comfirmed by operation.The diagnostic accuracies of low-dose CT and echocardiography were 88.1% and 90.5% respectively,which was no statistical difference(P=0.825>0.05).15 cases of CTS(15/18,83.33%)were caused by the compression of the vessels,in which there were 9 cases by pulmonary artery sling,3 cases by vascular ring,3 cases by double aortic arches.Conclusion Low-dose CT can accurately diagnose CHD with CTS and provide important information for clinical practice.
