The FEAT trial (Follow-up of Endovascular Aneurysm Treatment) is designed as a prospective, single-center, follow-up study. 100 Patients will be enrolled in this study. These patients will undergo additional MRA-examinations the day before EVAR, the day after EVAR, 6 months and 1 year after EVAR. These patients also participate in the conventional CTA follow-up scheme which comprises a pre- and post-operative CTA and a CTA yearly thereafter. Coagulation parameters in the blood will be measured before and 1 year after EVAR.
