Abstract:
ObjectiveTo explore the value of multislice computed tomography (MSCT) threedimensional reconstruction in the diagnosis and evaluation of left pulmonary artery sling (LPAS) and airway stenosis.MethodsRetrospective analyses were performed for 12 cases of LPAS with tracheobronchial abnormalities.ResultsThe clinical types were ⅠA (n=3),ⅠB (n=1),ⅡA (n=3),ⅡB (n=4) and special (n=1).All of them had concurrent tracheobronchial stenosis.Tracheobronchial stenosis was short (n=8) or long (n=4).Among 6 cases with other cardiac malformations,there were atrial septal defect (n=1),ventricular septal defect (n=1) ,patent ductus arteriosus (n=1) and persistent left superior vena cava (n=1) while another two cases had patent foramen ovale.Bronchoscope revealed complete tracheal cartilage ring (n=2),trachomalacia (n=1),epiglottis softening (n=2) and laryngomalacia (n=3).ConclusionAs an ideal imaging modality for simultaneously identifying LPAS and associated tracheobronchial anomalies,MSCT airway and vascular threedimensional reconstruction imaging provides important information for PSA classification.
