Aberrant right subclavian artery (arteria lusoria) is an uncommon aortic arch anomaly that may cause dysphagia due to extrinsic esophageal compression. Management can be especially challenging in pediatric patients, in whom no well-established standard of care exists. We report the case of a 13-yearold boy with a 6-month history of progressive dysphagia and weight loss. Computed tomography angiography demonstrated an aberrant right subclavian artery associated with a 9.61 mm Kommerell diverticulum. A staged hybrid approach was undertaken. The first stage consisted of a right common carotidsubclavian bypass through a supraclavicular approach using a ringed expanded polytetrafluoroethylene graft. Endovascular exclusion was then attempted with an Amplatzer AVP II device; however, proximal deployment failed because of inadequate anchoring related to the Kommerell diverticulum and worsening esophageal compression. The device was repositioned distally, and thoracic endovascular aortic repair was subsequently performed to achieve definitive exclusion while avoiding sternotomy. The postoperative course was uncomplicated, with complete resolution of dysphagia within the first postoperative week. At one, three, six, and 12 months, the patient remained asymptomatic, with weight gain, no neurologic or vascular complications, and imaging confirmation of complete exclusion, graft patency, and absence of endoleak. This case supports the technical feasibility of a staged hybrid repair with TEVAR after unsuccessful plug exclusion in a selected pediatric patient.
