Key result
Endovascular abdominal aortic repair (EVAR) showed no statistically significant difference in overall survival rates compared to open surgical repair (OSR) in patients with infrarenal AAA.
Why the study?
It was unknown whether EVAR confers higher survival rates compared to OSR in patients with infrarenal abdominal aortic aneurysm.
Does endovascular abdominal aortic repair (EVAR) improve overall survival rates in patients with infrarenal abdominal aortic aneurysm (AAA) compared to open surgical repair (OSR)?
Does endovascular abdominal aortic repair (EVAR) improve overall survival rates in patients with infrarenal abdominal aortic aneurysm (AAA) compared to open surgical repair (OSR)?
Endovascular and open surgical repair of infrarenal abdominal aortic aneurysms have comparable overall survival rates.
Answers are grounded in this paper and cite their sources.
Supports comparable survival with EVAR or OSR; leaves open need for randomized trials to guide practice.
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 higher Survival rates? The outcomes assessed were the overall survival rates in both techniques. The best evidence showed that there is no statistically significant difference between EVAR and OSR in survival rates.

Rahim et al. (2021) conducted a review in Infrarenal abdominal aortic aneurysm (AAA). Endovascular abdominal aortic repair (EVAR) vs. Open surgical repair (OSR) was evaluated on Overall survival rates. Endovascular abdominal aortic repair (EVAR) showed no statistically significant difference in overall survival rates compared to open surgical repair (OSR) in patients with infrarenal AAA.
