CT is the primary imaging modality used after aortic root repair. Distinction of normal findings from postoperative complications is imperative and requires optimization of acquisition parameters and interpretation with advanced postprocessing tools.
After aortic root surgery, findings can be categorized as complications within the aorta, complications outside the aorta, and benign postoperative changes. Distinction of normal findings from postoperative complications requires proper CT technique and an understanding of CT findings that require intervention.
