Brief Summary

To provide a robust view of EVAR surveillance at UHL, this study proposes to retrospectively assess the surveillance programme to get a better view of post-operative complications following endovascular aneurysm repair. It will seek to identify complications that required reintervention, establish reintervention rates, and attempt to compare which imaging modalities provide the best data on post-EVAR complications.

Outcome Measures

Primary Outcomes (1)

• Assessment of the type of complications detected by post-EVAR surveillance

  3 months

Study Arms (1)

Patients who have had an endovascular aneurysm repair and are under surveillance

Examine the follow up for this cohort and identify complications that required reintervention, establish reintervention rates, and attempt to compare which imaging modalities provide the best data on post-EVAR complications.

Eligibility Criteria

• Age: 16 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

This study will utilize an existing dataset at UHL which contains surveillance \& follow-up information for patients who underwent EVAR procedures for AAA or iliac aneurysms between March 2006 and December 2024.

You may qualify if:

• Included in registry of patients under surveillance with UHL Department of Vascular Surgery
• Under surveillance from March 2006 - December 2024
• Underwent EVAR for AAA or iliac aneurysm repair
• Surveillance performed with both CDUS and CTA with reports available

You may not qualify if:

• Not in registry for EVAR surveillance
• Not under surveillance during study period
• Underwent open repair for AAA or iliac aneurysm
• Both CDUS and CTA not available
