title: The Effect of Steroid Therapy on Postoperative Inflammatory Response after Endovascular Abdominal Aortic Aneurysm Repair.
abstract: Objectives:Unexpected systemic inflammatory response with high fever and increase in C-reactive protein (CRP) occurred frequently after endovascular abdominal aortic aneurysm repair (EVAR). This excessive inflammatory response affects the postoperative course. We evaluated the effects of steroid on the postoperative inflammatory response after EVAR.Methods:Steroid therapy, intravenous infusion of methylprednisolone 1000 mg just after the anesthesia induction, was started since December 2012. After induction of the steroid therapy, 25 patients underwent EVAR with steroid therapy (Group S). These patients were compared with the 65 patients who underwent EVAR without steroid therapy (Group C) in white blood cell count (WBC), CRP and maximum body temperature (BT) on postoperative day 1-5.Results:There was no significant difference in age, female gender, operation time, maximum aneurysm diameter between the two groups. There was no postoperative infective complication in the both groups. WBC did not differ between the two groups; however, CRP was significantly suppressed in Group S than in Group C on POD 1, 3 and 5. Also BT was significantly lower in Group S than Group C on POD 1, 2 and 3.Conclusions:Steroid pretreatment before implantation of the stent graft reduces the early postoperative inflammatory response after EVAR, without increasing postoperative infection.
