Impact of Supra-renal Fixation of EVAR on Hemodynamics of Renal Arteries (IFIXEAR)

To Assess Hemodynamic Disturbances to the Ostia of the Renal Arteries Generated by the Implantation of EVAR With a Suprarenal Fixation

The investigators conducted a bicentric prospective study to quantify the hemodynamic disturbances to the ostia of the renal arteries generated by the implantation EVAR with suprarenal fixation immediately postoperatively.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: endovascular aneurysm repair (EVAR) arm
every patients are in the same arm and have EVAR with supra-renal fixation
Patient will be enrolled when the decision of an endovascular procedure with supra renal fixation is required. Before the intervention, Duplex scan will be necessary to evaluate renal arteries ostia. This exam will be realised in the month after the intervention and one year later.
