Aortic Aneurysm, Abdominal, Endovascular Procedures, Renal Artery Stenosis
Conditions
Brief summary
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.
Interventions
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.
