Impact of Supra-renal Fixation of EVAR on Hemodynamics of Renal Arteries (IFIXEAR)
March 9, 2020 updated by: Centre Hospitalier Universitaire de Besancon
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.

- Interventional Model: SINGLE_GROUP
- Masking: NONE
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.
