Predicting 1-year mortality after elective abdominal aortic aneurysm repair

Abstract

Predictors of 1-year mortality can identify patients less likely to benefit from elective AAA repair. These factors differ for open repair vs EVAR and should be considered in individual patient decision-making. Our EVAR model had less impact on 1-year survival, even if CHF and large AAA diameter were present. However, a combination of age, COPD, renal insufficiency, and need for suprarenal clamping have significant impact on 1-year mortality after open AAA repair. Consideration of these variables should assist decision-making for elective AAA repair, especially in borderline cases.

Comparison of Survival Rates for Abdominal Aortic Aneurysm Treatment Methods

“…These data were consistent with a recently published study that showed no influence on 1-year mortality after endovascular repair [37]. Our EVAR group follow-up continued for 4 years and then was mathematically extrapolated.…”

Endovascular Chimney Technique for Juxtarenal Abdominal Aortic Aneurysm: A Systematic Review Using Pooled Analysis and Meta-Analysis

“…Together, the CG mortality was significantly lower than the 20% mortality caused by open surgical repair, of which patients with symptomatic and/or ruptured were excluded for the analysis. 15,32,33 In this study, the final occurrences of type I and type II endoleaks were 11.8% and 8.1%, respectively. The results were consisted with the findings of meta-analysis that the event-occurring rate of endoleaks during follow-up was 18% (95% confidence intervals, 14e23%).…”

The Outcomes of Endovascular Aneurysm Repair with the Chimney Technique for Juxtarenal Aortic Aneurysms

“…10) Less invasive treatments, such as Ch-EVAR might therefore be more appropriate than open surgery. The therapeutic efficacy and safety of endovascular treatments for JAAs have been reported.…”
