Abstract

Vascular rings are a diagnostic and therapeutic challenge for pediatricians. Many diagnostic modalities contribute to the detection of these rare congenital vascular anomalies. The role of flexible bronchoscopy is still being debated. We present 3 cases to emphasize the usefulness of pediatric flexible bronchoscopy (PFB) in the early diagnosis and postoperative evaluation of vascular rings. In patient 1, PFB was performed before conventional techniques were available. A right aortic arch with a retroesophageal aortic diverticulum and mirror-image branching was later confirmed. In patients 2 and 3, pulmonary artery slings could not be detected clearly by imaging studies before PFB was performed. PFB was arranged again postoperatively for these 2 patients, because of difficulty weaning patient 2 from ventilator support and persistent respiratory distress in patient 3. In conclusion, we expect that more vascular rings will be diagnosed using PFB. This instrument is also useful in making a decision for surgery, and for detecting associated tracheobronchial anomalies preoperatively, assuring appropriate correction intraoperatively, and monitoring the condition of vascular rings postoperatively.
