p-value: p=0.033
In a retrospective cohort of AAA patients, EVAR was associated with similar hospital mortality but lower overall survival compared to open repair, likely driven by the older age of the EVAR cohort.
EVAR linked to lower survival in unadjusted cohort; leaves open whether age or selection bias explains difference in AAA repair.
BACKGROUND: Endovascular aneurysm repair (EVAR) has dramatically changed the management of abdominal aortic aneurysms (AAAs) as the number of open aneurysm repairs have declined over time. This report compares AAA-related demographics, operative data, complications, and mortality after treatment by open aneurysm repair or EVAR. METHODS: We retrospectively reviewed 136 patients with AAAs who were treated over an 8-year time period with open aneurysm repair or EVAR. RESULTS: The mean age of the EVAR group was higher than that of the open repair group (p=0.001), and hospital mortality did not differ significantly between groups (p=0.360). However, overall survival was significantly lower in the EVAR group (p=0.033). CONCLUSION: Although EVAR is the primary treatment modality for elderly patients, it would be ideal to set slightly more stringent criteria within the anatomical guidelines contained in the instructions for use of the EVAR device when treating younger patients.

Bae et al. (2017) conducted a cohort in Abdominal aortic aneurysms (AAAs) (n=136). Endovascular aneurysm repair (EVAR) vs. Open aneurysm repair was evaluated on Overall survival (p=0.033). Endovascular aneurysm repair was associated with significantly lower overall survival compared to open repair in patients with abdominal aortic aneurysms (p=0.033).
