Left pulmonary artery sling: why is virtual CT bronchoscopy important? Case report

Abstract

Abstract Background Many causes of vascular rings may present as stridor among children. Co-occurrence of tracheal anomaly in left pulmonary artery sling (LPAS) is very common and needs special attention. Case presentation We report a case of an infant who presented with expiratory stridor and wheezing. A preliminary chest x-ray revealed no significant findings. CT and virtual bronchoscopy confirmed the diagnosis of LPAS with associated distal tracheal stenosis. He underwent surgical correction with good results in the follow-up period. Conclusions Virtual bronchoscopy may help to decide the type of operation and to avoid a potentially invasive bronchoscopy in LPAS.
