Fenestrated endovascular aneurysm repair (FEVAR) is an established technique used to treat complex aortic aneurysms (TAAAs), with satisfactory early and midterm results. Postoperative renal function worsening is a common adverse event after FEVAR of complex aneurysms and is associated with prolonged hospital stay, higher morbidity, and long-term mortality in the peri-operative period and during follow-up. One of the more common causes of renal function worsening is contrast-induced nephropathy resulting from the use of iodinated contrast medium (ICM). Automated carbon dioxide (CO2) angiography has been proposed as an alternative to ICM for standard endovascular aneurysm repair (EVAR) in consideration of its absence of nephrotoxicity that can be of further help in preserving renal function. In adjunct, hybrid room and fusion imaging (FI) technologies are useful tools to reduce intraoperative contrast medium and fluoroscopy time. In literature there are few reports regarding the use of CO2 for fenestrated endografting repair of complex aortic aneurysms. The aim of the present study is to report the possibility to combine the use of automated CO2 angiographies and Fusion Imaging to obtain zero- or near zero- contrast FEVAR for complex aortic aneurysms.
