Abstract
- College of Medicine, Ulsan University, Seoul, Korea The vascular rings comprise less than 1% of congenital cardiovascular malformations and can be overlooked because they are rare diseases and show nonspecific respiratory symptoms such as wheezing or airway obstruction or apnea. This case is a 2-months old infant who had been repaired patch closure due to ventricular septal defect, but failed to wean from ventilator. Chest CT showed right main stem bronchus lying between right pulmonary arery and right descending aorta, bronchoscopy showed right main bronchus was compressed by extrinsic pulsating mass which were descending aorta and Kommerell's diverticulum . After aortopexy and transfer of subclavian artery, this patient was able to be extubated and is now free of respiratory symptoms. When there is failure to weaning of ventilator and persistent bronchial obstruction and emphysema, we should have more vigorous effort to seek the cause of bronchial obstruction, using bronchoscope and chest CT.
