Objective: Postimplantation syndrome (PIS) is a postoperative syndrome that occurs after endovascular aneurysm repair (EVAR), accompanied by high fever, leukocytosis, and high serum C-reactive protein (CRP). Its pathogenesis and clinical meaning are still under discussion. Here, we evaluate the relationship between postoperative fever after EVAR and graft fabric focusing on Endologix Powerlink® and AFX® (EPL/AFX).Materials and Methods: From January 2015 to July 2017, data on elective EVAR for abdominal aortic aneurysm (AAA) using mainbody were retrospectively collected. The primary endpoint was maximal postoperative fever.Results: We identified 128 patients who underwent elective EVAR for AAA (105 males, 82%; aged 57–90, median: 74 years). The median maximal postoperative fever was 37.8°C (36.6–39.7°C): polyester graft, 38.2°C (37.1–39.7°C); Excluder®, 37.8°C (36.6–39.2°C); and EPL/AFX, 37.7°C (37–38.7°C). The maximal postoperative fever with a polyester graft was significantly higher than that with an expanded polytetrafluoroethylene (ePTFE) graft (p<0.001). However, there was no difference between Excluder® and EPL/AFX (p=0.214).Conclusion: In this study, it was found that polyester grafts are significantly associated with PIS after elective EVAR for AAA. If patient anatomy is permitted, it may be better to choose the ePTFE graft, especially for patients with a poor general condition.

Patients with postoperative CKD progression have an increased frequency of aneurysm-related death. The presence of a shaggy aorta, absence of oral beta-blocker administration and an increased preoperative creatinine level are independent predictors of early postoperative CKD progression.

We describe the case of a 74-year-old man with a thoracic aortic aneurysm with a bovine arch who underwent fenestrated endovascular repair of aortic arch aneurysm using the Najuta stent graft (Kawasumi Laboratories, Inc, Tokyo, Japan). He has had a previous endovascular aneurysm repair and femoropopliteal bypass for abdominal aortic aneurysm combined with peripheral arterial disease. The Najuta stent graft was inserted and deployed at zone 0 with delicate positional adjustment of the fenestration of the stent graft to the brachiocephalic trunk. There was no endoleak or complication. His postoperative course was uneventful. At 7-month follow-up, complete exclusion of the aneurysm was noted. The Najuta stent graft repair of aortic arch aneurysms is a safe and effective treatment option for patients with a bovine arch.
