Altered renal functions in patients with occlusion of an accessory renal artery after endovascular stenting of an infrarenal aneurysm

The decrease in renal function was more pronounced in patients with ARA after EVAR when compared with patients without ARA undergoing EVAR. In patients with ARA, the observed decline in renal function was significantly distinct in patients presenting NF preoperatively. Consequently, the risk of IF after EVAR seems to be increased in patients with ARA and normal preoperative renal function.
