Acute Kidney Injury After Endovascular Repair of Abdominal Aortic Aneurysm

Introduction:The aim of this study is to determine the prevalence of acute kidney injury after endovascular repair of an abdominal aortic aneurysm and examine the risk factors. Patients and Methods:Patients who underwent endovascular repair of abdominal aortic aneurysms between November 2013 and March 2019 were examined retrospectively.We have excluded the patients who had ruptured abdominal aortic aneurysms and were undergoing emergency repair and those who underwent endovascular procedures, such as renal or iliac stenting, in addition to endovascular repair.Other than procedural exclusion criteria, patients dependent on dialysis, those having acute kidney injury and those with missing data were not included in the study.The acute kidney injury was diagnosed in patients according to Kidney Disease: Improving Global Outcomes definition.Results: Out of 185 patients who underwent elective endovascular repair of abdominal aortic aneurysms, 167 patients were included in this study.There was no in-hospital mortality or requirement of reintervention.An acute kidney injury developed in 23 (13.8%) patients and 6 (3.3%) of these patients needed hemodialysis.The preoperative renal functions of patients who needed hemodialysis after the endovascular repair were significantly impaired than those who did not need hemodialysis [p< 0.001; CI (25.79-61.62)]. Conclusion:With new acute kidney injury definitions, the frequency of endovascular aneurysm repair-related acute kidney injury is much higher than expected.If acute kidney damage has developed after an endovascular repair, it is permanent and patients should be closely monitored for renal function.
