Truncus arteriosus is a rare congenital cardiac anomaly characterized by failure of conoseptal separation resulting in a single arterial trunk supplying both the pulmonary and systemic circulation. Diagnosis has historically been made with fetal echocardiography, and palliative surgery performed frequently in the neonatal period. Cross-sectional imaging is typically reserved for post-operative complications. However, due to lower dose radiation and faster scanners, preoperative CT angiography imaging is becoming more common with the increasing use of cardiac EKG-gated CT angiograms, requiring pediatric imagers to be familiar with the diagnosis of the truncus arteriosus spectrum.

CT with 4D cine imaging can non-invasively and dynamically characterize airways for various pathologies, such as airway caliber fluctuations in tracheobronchomalacia, intermittent compression by cardiovascular or other mediastinal structures, or constriction from anatomic anomalies like those associated with craniofacial syndromes. However, optimal interpretation of dynamic airway CT studies requires an understanding of the impact of such extrinsic factors as the presence of support apparatus (e.g., endotracheal tube, enteric tube), level of required respiratory support (e.g., positive end-expiratory pressure), and differences in positioning (e.g., with jaw thrust). We have performed more than 100 pediatric cases of dynamic airway CT under a variety of conditions, in patients who range from free-breathing to ventilator-dependent, and for a variety of pathologies. In this educational exhibit, we will consider how to balance and tailor extrinsic factors when using dynamic CT for the guidance of airway management, in order to meet diagnostic considerations and supplement other cardiopulmonary investigations, including cases with bronchoscopic and surgical correlates.
