Postimplantation Syndrome After Endovascular Aortic Aneurysm Repair in an Elderly Patient

Abstract

Endovascular procedures have been proposed as minimally invasive alternative treatments, allowing safe and effective aortic aneurysm repair. Despite the potential benefits, endovascular stent grafting may elicit an unexpected systemic inflammatory response, called postimplantation syndrome (PIS). The main features of PIS include fever, elevated C-reactive protein levels, leukocytosis and/or coagulation disturbances, perigraft air on abdominal computed tomography, and no evidence of infection. The main management of PIS is supportive care. Antibiotics have no clinical benefit. We report a case of PIS after endovascular aortic aneurysm repair in an elderly patient.
