Vascular rings are a rare congenital anomaly of the aortic arch, in which a ring-shaped structure forms, surrounding the trachea and/or esophagus, potentially causing compression. We describe the case of a 14-month-old female patient with failure to thrive secondary to dysphagia, and a vascular ring formed by a right aortic arch, an aberrant left subclavian artery, and a left ligamentum arteriosum. Surgical repair involved ligamentum arteriosum division, Kommerell's diverticulum obliteration, and left subclavian artery re-implantation into the left carotid artery. Endoscopy and EndoFLIPTM evaluated the intraoperative improvement in esophageal narrowing and impedance, respectively. The postoperative period was uneventful, and follow-up visits demonstrated dysphagia resolution and a patent re-implanted left subclavian artery.
