Vascular rings are congenital abnormalities of the aortic arch vascular system that compress the trachea and esophagus. A review of long-term outcomes suggests that chronic feeding difficulties can persist following surgical repair of vascular rings. Previous reports of postoperative vascular ring division outcomes indicate that chronic esophageal symptoms may persist following repair, though most available data focuses on persistent respiratory symptoms. It is therefore the aim of this article to summarize and organize recent evidence reporting the frequency, presentation, and management of feeding difficulties following vascular ring repair in pediatric patients. Pathophysiologic mechanisms for postoperative esophageal symptoms may include residual compression from an unresected diverticulum of Kommerell or delayed repair leading to chronic esophageal dysmotility despite correction of esophageal compression. Guidance on the management of feeding difficulties following vascular ring repair is limited. The authors describe success in one case with nasogastric tube feeding and interdisciplinary evaluation. Consensus regarding the management of feeding difficulty following vascular ring repair is needed.
