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.
Patients 18 years of age and older,
Patients who have received EVAR ,
Detection of endoleak and/or with an aneurysmal sac enlargement greater than or equal to 5 mm over 6 months.
Minor patients,
absence of endoleak and growth of the aneurysmal sac (greater than or equal to 5 mm over 6 months),
patient under guardianship, curators, safeguard of justice,
patient deprived of liberty,
