Outcomes of Endovascular Aneurysm Repair With 2 Different Endograft Systems With Suprarenal Fixation in Patients With Hostile Infrarenal Aortic Anatomy

Abstract

Objective: To evaluate 2 different aortic endograft systems with suprarenal fixation in patients with unfavorable neck morphology. Methods: A prospective observational study assigning patients with abdominal aortic aneurysm with unfriendly neck anatomy treated with 2 different endograft systems (Endurant and Zenith) was conducted. The log-rank test was applied to investigate the differences in cumulative outcome parameters. Results: Successful endograft implantation was achieved in all patients. Requirement for troubleshooting techniques was similar in the 2 groups ( P = .156 and P = .081, respectively). In-hospital procedure-related morbidity occurred in 7 patients (Zenith vs Endurant, P = .690). Freedom from any type of endoleak and overall mortality did not differ significantly between the groups (log-rank test, P = .068 and P = .087). Reinterventions were more commonly required in the Zenith group (log-rank rest, P = .041), and were all nongraft/aneurysm-related. Conclusions: Similar performances of the Zenith and the Endurant endograft systems were demonstrated.
