title: Follow-Up of Persistent Tracheal Stenosis After Surgery for a Double Aortic Arch.
abstract: Persistent respiratory symptoms often occur after surgical repair of double aortic arch (DAA). Most often, symptoms are relatively mild and tend to be self-limited and improve with growth. Multidetector computed tomography (MDCT) imaging can be used to obtain needed anatomic information regarding the potential for extrinsic airway compression and is minimally invasive, safe, and readily available after surgery. We herein report the cases of two patients with persistent airway symptoms after surgical therapy for a double aortic arch. One of the patients eventually required aortopexy in order to achieve complete relief from recurrent symptoms of airway compression. In the other case, wheezing persisted following surgical division of the vascular ring, but it resolved over time without further intervention. In both cases, serial follow-up imaging with computed tomography scans was informative and helped guide management decisions.
