Arms of the Study
Arm 1
Experimental
all cohort
Patients will perform CTA 1 months after the EVAR procedure. Following CTA, an ultrasound examination which will include a 3D reconstruction and CEUS will be performed using SONOVIEW contrast agent. The dimensions and volume of the aorta will be compared to the measurements in CTA using the fusion method. In the case of endoleak type 1 or 3 the patient will be urgently refered to endovascular repair . In the case of endoleak type 2 or a normal exam the patient will undergo another fused exam with CEUS at 6 month . In the case of endoleak type 2 with a growth of more than 1 cm in the aneurysm diameter , the patient will be refered to endovascular repair. In the case of a normal exam or an endoleak type 2 with a shrinkage of 1 cm or more ,the patient will undergo another fused exam with CEUS at 12 months. At any case of a new endoleak type 1 or 3 the patient will undergo CTA.
