Concordance of Three Imaging Methods by Dynamic CT, Contrast Ultrasound and CT Angiography in the Characterization of Endoleaks in Patients With an Aortic Endoprosthesis

Among patients who have undergone EVAR, there is a significant risk of 20-50% endoleak. These endoleaks often require secondary interventions to reduce the risk of expansion or rupture. Currently, three-phase CT angiography and CEUS ultrasound are recommended in the post-operative monitoring of EVAR but these remain limited in characterizing the type and source of endoleak. In this study the investigators will study the interest of d-CTA for a better detection and characterization of endoleaks.
