Abstract:
We report a case of vascular ring with tracheal stenosis, which might be related to a prolonged endotracheal intubation. A symptomatic 2-month-old boy was admitted to our institution after prolonged intubation without a definite diagnosis. His symptoms were stridor and dyspnea, but not dysphagia. Echocardiography detected a vascular ring and this was confirmed by computed tomography and magnetic resonance imaging (MRI) (Edwards IA type). The left anterior aortic arch was divided distal to the left subclavian artery through left thoracotomy and the ligamentum arteriosus was not identified. On postoperative day (POD) 2, endotracheal extubation was unsuccessfully attempted. Further examination such as MRI and bronchoscopy revealed intimal hyperplasia of the trachea with mild compression of the trachea from the outside. We performed aortopexy and division of the small long ductus which might not be a mechanism of the tracheal compression through right thoracotomy in the second operation with successful extubation on POD 3. The patient has been discharged from the hospital and followed up at the outpatient clinic without any symptom. Tracheomalacia was a common associated anomaly in vascular ring. However, other mechanisms such as inflammatory reaction associated with prolonged intubation should be considered and be avoided in the pediatric population.
