This study states that Renal dysfunction can be a prohibitive risk for open repair of complex thoracoabdominal aortic aneurysms (TAAAs) and pararenal aortic aneurysms (PRAAs). However, the effect of renal dysfunction from fenestrated and branched endovascular aneurysm repair (FB-EVAR) on outcomes is poorly defined. Our objective was to review the association of renal function on patient survival after FB-EVAR.
The present study reviewed the clinical data of consecutive patients enrolled in a prospective nonrandomized study to investigate FB-EVAR for PRAAs and TAAAs at a single institution with 1 year of follow-up (2013-2017). The patients were categorized by preoperative chronic kidney disease (CKD) classification, and the early- and long-term mortality was assessed. During the study period, 231 patients had undergone FB-EVAR for 80 PRAAs, 89 type I-III TAAAs, and 62 type IV TAAAs. The mean age was 74.6 ± 6.7 years, and 71% were men. Of the 231 patients, 126 had had CKD stage 1-2, 96 CKD stage 3, and 9 CKD stage 4-5 (all with baseline creatinine >2.0 mg/dL).
