Abstract
A best evidence topic has been constructed using a described protocol. The three-part question addressed was: In patients with Infrarenal abdominal aortic aneurysm (AAA), Does endovascular abdominal aortic repair (EVAR), AS compared to open surgical repair (OSR), has lower secondary rupture rates? The outcomes assessed were the secondary rupture rate in both techniques. The best evidence showed that The OSR has statistically significant lower secondary rupture rates than the EVAR.
Highlights
This BET was designed using a framework outlined by the Interna tional Journal of Surgery [1]
This format was used because a pre liminary literature search suggested that the available evidence is insufficient to perform a meaningful meta-analysis
After resuscitating a 70-year-old man who presented to the emer gency department (ED) with haemorrhaogic shock due to secondary rupture after open repair of infrarenal abdominal aortic aneurysm, one of the ED registrars asked; which modality of AAA repair has lower secondary rupture rates; endovascular abdominal aortic repair (EVAR) or Open repair?
Summary
This BET was designed using a framework outlined by the Interna tional Journal of Surgery [1]. This format was used because a pre liminary literature search suggested that the available evidence is insufficient to perform a meaningful meta-analysis. A BET provides evidence-based answers to common clinical questions, using a system atic approach of reviewing the literature
