This is a randomized prospective monocentric study to evaluate the benefits of a 3D rotational acquisition (3DRA) to assess technical success after treatment of infra-renal aneurysm with bifurcated endograft. Patients will be randomized between the standard strategy (2D angiography at the end of the procedure and angioCT-scan before discharge) and the new strategy (3DRA at the end of the procedure). Expected findings are a reduction of radiation exposure and contrast medium used during the hospital stay, with a similar resolution between angioCT-scan and 3DRA to depict the main complications after EVAR (occlusion, kinking, endoleak). Furthermore, any complication depicted after 3DRA group could benefit from an additional procedure during the same operating time, and therefore avoid a second intervention for the patient.

NONE
3DRA allows CT-like reconstructions. It requires less X-rays and contrast medium than standard angioCT-scan. Furthermore, it can be performed in the operative room, during the procedure. Therefore, use of 3DRA should allow reduction of dose, contrast-medium and reintervention when compared to technical success assessment with angioCT-scan.

Effective Dose
Total exposure to radiation in mSv
Time frame: Single 1 day - At patient discharge
Contrast Medium
Total amount of contrast medium used (mg of Iodine)
Time frame: Single 1 day - At patient discharge
Reintervention rate
Number of secondary procedures due to initial technical issues in both group during the first month
Time frame: During the first 30 days
Additional procedure
Number of additional unplanned procedures during the initial operating time, thanks to complications depicted by respectively the 2D angiography or the 3D rotational angiography.
Time frame: During surgery
