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. ⋯ 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.
