Why the study?
Does risk stratification based on first postoperative CTA predict AAA-related adverse events in patients undergoing EVAR?
Does risk stratification based on first postoperative CTA predict AAA-related adverse events in patients undergoing EVAR?
Patients with an adequate seal and no endoleak on their first postoperative CTA after EVAR have a very low risk of AAA-related events up to 5 years, suggesting less vigilant follow-up may be safe.
No takes yet. Share an insight, caveat, or question.
May support risk-stratified EVAR surveillance; leaves open whether de-escalation is safe without prospective validation.
Baderkhan et al. (2018) studied this question.
