Abstract

Background: In this study, we aimed to evaluate the performance of modular and unibody endografts for the endovascular repair of abdominal aortic aneurysm (AAA).

Methods: Between January 2012 and December 2017, 130 elective infrarenal abdominal aortic aneurysms treated in an endovascular manner were retrospectively evaluated. Sixty-six patients with the modular type (Medtronic EndurantTM II and Lifetech AnkuraTM AAA) and 64 patients with the unibody type (Endologix AFX®) were compared with regards to early and postoperative one-year results.

Results: There was one in-hospital mortality (0.8%) in the modular group. There was no difference in postoperative first-year mortality rate between the two groups (p = 0.678). Loco-regional anesthesia was used more often in the unibody group [34 patients (53.1%)] and the use of general anesthesia was higher in the modular group [56 patients (84.8%)] (p < 0.001). While the duration of the procedure was shorter in the unibody group (p < 0.001), no statistically significant difference was found in the duration of fluoroscopy (p = 0.813) and the amount of contrast agent used (p = 0.553). The follow-up period in the intensive care unit was shorter in the modular group (p < 0.001). Moreover, the five-year survival rate was similar between the groups (84.8% in the modular group and 78.4% in the unibody group, log-rank p = 0.703).

Conclusions: The results obtained in our study show that modular and unibody grafts are effective and reliable, although there are some negligible differences in the early period.
