Surveillance Computed Tomographic Arteriogram Does Not Change Management before 3 Years in Patients Who Have a Normal Post-EVAR Study

For patients who have a normal CTA with no endoleak 1 month after EVAR, it is reasonable to consider less-frequent CTA surveillance because no significant complications requiring intervention occurred before 3 years. This would decrease unnecessary CTAs and health care expenditures as well as minimize patient exposure to radiation and intravenous contrast.
