Abstrakt:	Background: The post-implantation syndrome may occur shortly after endovascular aneurysm repair in patients treated for abdominal aortic aneurysm. Different types of biomaterials may provoke varying inflammatory responses in patients receiving different endografts. The purpose of this article is to evaluate the PIS after EVAR and the influence of different types of device fabric. Methods: All patients submitted to elective AAA endovascular repair at our institution from January 2014 to December 2019 were enrolled. The PIS was defined by a body temperature of >38°C and WBC >12'000/μl without any evidence of an infection during (48h) the observation period. Results: Three hundred and sixty-seven patients (89% males) were enrolled in this study and post-implantation syndrome occurred in 41 cases (11.2%). The incidence of PIS was significantly higher (P< 0.001) in patients treated with polyester stent grafts (39/201, 19,4%) compared to patients with PTFE stent grafts (2/166, 1,2%). CRP was related to the presence of PIS with a cut-off values of 109.31 mg/dL (P = 0.0052). The median in-hospital stay considering the polyester group was 6,2 days, while in the PTFE group it was 5,6 days (P = 0.04). Conclusions: The postoperative inflammatory response after EVAR seems significantly higher by using polyester stent graft compared to PTFE devices. CRP could be a useful biomarker in defining PIS. Multi-center studies are necessary to confirm these data. Competing Interests: CONFLICT OF INTEREST None (Copyright © 2021. Published by Elsevier Inc.)
