Key result
Age over 76.5 years significantly increased the risk of 30-day mortality (OR 48.89) following endovascular thoracic and abdominal aortic repair under general anesthesia.
Why the study?
The study was conducted to analyze outcomes and identify predictors of 30-day mortality and complications in patients undergoing EVAR and/or TEVAR under general anesthesia.
Observational (n=151)
No
Advanced age (>76.5 years) and severe systemic or local-vascular complications are strongly associated with increased 30-day mortality following EVAR or TEVAR under general anesthesia.
Advanced age (>76.5 years) signals high 30-day mortality risk after EVAR/TEVAR; hypothesis-generating and should not yet change practice.
Background: Recently, endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR), have been used for treatment of thoracic and abdominal aortic aneurysms.The purpose of this study was to analyze the outcome and predictors for 30day mortality and complications, in patients that underwent EVAR and/or TEVAR under general anesthesia.Methods: In this study, 151 cases of EVAR and/or TEVAR under general anesthesia in 140 patients during 2009-2017 were studied.The primary outcome was 30-day mortality after surgery.Multivariate logistic regression analysis was used, to clarify risk for postoperative 30-day mortality.Results: Postoperative 30-day mortality rate was 9.9% in the study population (10.3% in EVAR, and 9.3% in TEVAR, respectively).Seventy-two cases (47.7%) experienced postoperative complications within 30 days.Elderly older than age 76.5 (odds ratio [ORs] = 48.89,95% confidential interval [95% CI] 1.40-1,710.25,P = 0.032), technically expertness (OR = 0.01, 95% CI 0.00-0.40,P = 0.013), severity of systemic complications (OR = 23.24,95% CI, 2.27-238.24,P = 0.008), and severity of local-vascular complications (OR = 31.87,95% CI, 1.29-784.66,P = 0.034) were significantly associated with 30-day mortality.Conclusions: This study revealed that elderly, technically expertness, and severity of systemic and local-vascular complications were associated with 30-day mortality of EVAR and TEVAR in aortic aneurysm.

Kim et al. (2019) conducted an observational in Thoracic and abdominal aortic aneurysms (n=151). Age > 76.5 years vs. Age ≤ 76.5 years was evaluated on 30-day mortality (OR 48.89, 95% CI 1.40-1710.25, p=0.032). Age over 76.5 years significantly increased the risk of 30-day mortality (OR 48.89) following endovascular thoracic and abdominal aortic repair under general anesthesia.
