Purpose or Case Report: The purpose of this educational presentation is to provide a pictorial review to promote recognition and understanding of the embryology, anatomy and spectrum of interruption of the aortic arch (IAA) in children.
Methods & Materials: Interruption of the aortic arch will be classified according to the the Celoria-Patton system. There are 3 main categories of IAA (A, B and C), which are defined by the location of the discontinuity. In addition to the three categories, there are 3 subtypes for each, for a total of nine types. Illustrative examples will be provided from clinical case material.
Results: Imaging findings will be reviewed, with an emphasis on CT/MR appearances, and discussion of important associated conditions and findings. Specific syndromes associated with IAA will be highlighted, and attention will be given to surgical intervention and post-operative imaging.
Conclusions: After reviewing this educational exhibit the reader will have a framework for recognizing and understanding IAA in the pediatric age group. They will have reviewed pre- and post-operative CT/MR imaging findings as well as the context and important associated findings.
