Patients and Methods
This study was reviewed and approved by the Institutional Review Board of Duke University, and the need for individual patient consent was waived.
Results
During the study interval, 332 TEVAR procedures were performed in 297 patients (Table 1). Procedures included descending only (66%), hybrid arch (19%), and hybrid thoracoabdominal (15%) repair. The 30-day/in-hospital mortality rate was 6%. The rates of postoperative permanent paraparesis/paraplegia and stroke were 1.8% and 1.8%, respectively. Acute kidney injury requiring any postoperative dialysis occurred after 3.3% of procedures. Operative characteristics are presented in Table 2. Primary
Comment
Recent reports of sobering rates of reintervention and late death [4, 5] have raised questions about the durability and appropriate use of TEVAR. In this large, single-center series, we demonstrate that TEVAR can be performed with a low rate of reintervention (12%) and high rate of aorta-specific long-term survival (92% at 6 years). Further, reintervention rates decreased by 50% after the initial tercile of patients treated, likely related to the availability of newer-generation devices over

2022, Annals of Thoracic SurgeryCitation Excerpt :This retrospective observational study utilized a prospectively maintained institutional TEVAR database from a referral aortic center (Duke University Medical Center, Durham, North Carolina) to identify all adult patients undergoing TEVAR between January 2005 and December 2018. Selection of patients for TEVAR, techniques of device delivery and deployment, and postoperative surveillance have been previously described.8-12,14 Devices were sized in accordance with device instructions for use.
Long-term outcomes of the conformable TAG thoracic endoprosthesis in a prospective multicenter trial
2021, Journal of Vascular SurgeryCitation Excerpt :One death had occurred during reintervention at an outside facility at 20 months after the initial implant. Freedom from all-cause mortality at 5 years (60%) was similar to the 5-year mortality observed with surgical repair performed at five centers of excellence (5-year survival ranging from 54% to 69%) in a systematic review by Shah et al.17 Similarly, Lee et al18 posited that the high late mortality rates (all-cause or otherwise) observed that TEVAR patients reflect a patient subset with coexisting comorbidities that could affect long-term survival more than any aortic pathology. The CTAG device performed well for two key surrogates for long-term endograft durability—minimal occurrence of late endoleaks and long-term aneurysm stability.
