Clinical Trial Summary

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.
