Background: Vascular rings with a Kommerell diverticulum (KD) most commonly occur in patients with a right aortic arch. We report on a less commonly seen subset of vascular ring patients—those with a double aortic arch and a KD. Methods: Between 2002 and 2017, 66 patients underwent an operation for a double aortic arch. Ten of those patients also had excision of a KD. We performed a retrospective medical record review of these patients to characterize their demographics and outcomes. Results: All 10 patients (7 male, 3 female) had a double aortic arch that was right dominant and also had a KD. The patients were a mean age of 4.9 ± 4.3 years (range, 6 months to 29 years), and median age was 4 years. All patients had preoperative computed tomographic angiography or magnetic resonance imaging and mean compression of the distal trachea of 63% ± 12% (range, 40% to 80%). The distal left arch was atretic in all patients. All patients underwent division of their left aortic arch, division of the ligamentum, and resection of the KD. The left subclavian artery was transferred to the left carotid artery in 2 patients. The mean size of the diverticulum was 9 × 10 mm. There were no major postoperative complications or readmissions. The postoperative length of stay was 3.1 ± 0.8 days. Five of the patients reported no related persisting symptoms. The remaining 5 patients reported substantial symptomatic relief with only minor respiratory symptoms. Conclusions: Vascular ring patients with a double aortic arch can also have a KD. In addition to dividing the smaller aortic arch and the ligamentum, we recommend excision of the KD.
