The purpose of this study is to determine the prevalence of tracheomalacia (TM) associated with different types of mediastinal aortic vascular anomalies in symptomatic children using paired inspiratory-expiratory multidetector computed tomography (MDCT). ⋯ Symptomatic pediatric patients with mediastinal aortic vascular anomalies have a relatively high prevalence of TM, especially those with IAC. Paired inspiratory-expiratory MDCT should be considered part of the routine preoperative evaluation of TM in symptomatic children with IAC and also has the potential to play a role in evaluating patients with other mediastinal aortic vascular anomalies.
