ACR Appropriateness Criteria® Thoracic Aorta Interventional Planning and Follow-Up

Expert Panels on Vascular Imaging and Interventional Radiology

Research output: Contribution to journalArticlepeer-review


Thoracic endovascular aortic repair (TEVAR) has undergone rapid evolution and is now applied to a range of aortic pathologies. Imaging plays a vital role in the pre- and postintervention assessment of TEVAR patients. Accurate characterization of pathology and evaluation for high-risk anatomic features are necessary in the planning phase, and careful assessment for graft stability, aortic lumen diameter, and presence of endoleak are paramount in the follow-up period. CTA is the imaging modality of choice for pre- and postintervention assessment, and MRA is an acceptable alternative depending on patient stability and graft composition. Lifelong imaging follow-up is necessary in TEVAR patients because endoleaks may develop at any time. The exact surveillance interval is unclear and may be procedure and patient specific. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.
