INTRODUCTION: Endovascular aneurysm repair (EVAR) has rapidly become the preferred management of abdominal aortic aneurysm (AAA). Sac regression status post-EVAR has been linked to clinical outcomes as well as the choice of EVAR device. The aim of this narrative review is to investigate the relationship between sac regression and clinical outcomes post-EVAR in AAA. Another aim is to compare sac regression achieved with the main EVAR devices.

AREAS COVERED: We carried out a comprehensive literature search on multiple electronic databases. Sac regression was usually defined as a decrease in the sac diameter (>10 mm) over follow-up. This revealed that individuals who had sac regression post-EVAR had significantly lower mortality, and higher event-free survival rates. Further, lower rates of endoleak and reintervention were observed in patients with regressing aneurysm sacs. Sac regression patients also had significantly lower odds of rupture compared to counterparts with stable or expanded sacs. The choice of EVAR device was also shown to impact regression, with the Fenestrated Anaconda showing favorable results.

EXPERT OPINION: Sac regression post-EVAR in AAA is an important prognostic factor as it translates to improved mortality and morbidity. Therefore, this relationship must be seriously taken into consideration during follow-up.
