Background: Current surveillance recommendations after thoracic endovascular aortic repair (TEVAR) include contrast-enhanced computed tomography (CT) scans at 1-, 2-, 6-, and 12-month intervals, with annual scans thereafter. Patient compliance with such schedules remains inconsistent for all etiologies of aortic disease. It remains unclear which boundaries prevent compliance and whether compliance is associated with improved aorta-specific outcomes. Methods: A retrospective analysis was performed of a multicenter health-care system's electronic medical records to include all patients who underwent TEVAR from July 1, 2011 to April 1, 2016. Patients were assigned a compliance score of 0 through 4 based on the number of images received at the recommended time intervals. Whether patients underwent any postoperative imaging within 1 year of discharge was also recorded. Patients who died within 12 months of discharge were excluded. Aorta-specific complications included postoperative sac expansion, rupture, or need for additional aortic intervention. Results: A total of 262 patients were included; of whom, 203 (77.5%) received at least one postoperative contrast-enhanced CT scan. Race, insurance status, and distance to hospital were not associated with 12-month compliance or compliance score (all P > 0.05). Regarding 12-month compliance, 76.2% of aneurysm patients, 81.6% of dissection patients, 72.2% of transection patients, and 72.2% of penetrating aortic ulcer patients underwent at least 1 CT scan within the first year (all P > 0.05). There were no differences in compliance score based on indication for repair. The overall aorta-related complication rate was 34.7%. TEVAR for dissection was associated with increased long-term aorta-specific complications (49.5%, P < 0.05 when compared with other indications). Conclusions: In this large, multihospital analysis of TEVAR outcomes, there was no difference in compliance among patients undergoing TEVAR for major indications, but patients with dissection who required TEVAR had a significant difference in aorta-specific complication rates. TEVAR for dissection should be subject to stricter surveillance guidelines than TEVAR for other indications.
