Reintervention Rates and Complications in Endovascular Aneurysm Repair (EVAR) and the Use of Colour Doppler Ultrasound (CDUS) and Computed Tomography Angiography (CTA) in Identifying Endoleak Complications

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.

About this study

From 2006 to 2024, the UHL EVAR programme collected scan information on patients following endovascular repair of abdominal aortic aneurysms (AAA) and iliac aneurysms. Prior to 2015, surveillance of EVAR patients was organized by referral only. Since January 2015, structured surveillance with CDUS and CTA was performed less than 6 weeks postoperatively and then continued with automatically scheduled US scans every 6 months. Surveillance with CDUS (performed by a vascular physiologist) and CTA (interpreted by a consultant radiologist). Data on individual surveillance and complications has been collected and is available for analysis.
