Previous reports have documented better outcomes after open abdominal aortic aneurysm (AAA) repair in tertiary centers compared with lower-volume hospitals, but outcome variability for endovascular AAA repair (EVAR) vs open AAA repairs in a large tertiary center using a Medicare-derived mortality risk prediction model has not been previously reported. In the current study, we compared the observed vs predicted mortality after EVAR and open AAA repair in a single large tertiary vascular center. ⋯ Despite treating patients with high preoperative risk status, we report a 10-fold decrease in operative mortality for EVAR and open AAA repair in a tertiary vascular center compared with national Medicare-derived predictions. High-risk patients should be considered for aneurysm management in dedicated aortic centers, regardless of approach.

Frailty, defined as a biologic syndrome of decreased reserve and resistance to stressors, has been linked to adverse outcomes after surgery. We evaluated the effect of frailty on 30-day mortality, morbidity, and failure to rescue (FTR) in patients undergoing elective abdominal aortic aneurysm (AAA) repair. ⋯ Higher mFI, independent of other risk factors, is associated with higher mortality and morbidity in patients undergoing elective EVAR and OAR. The mortality in frail patients is further driven by FTR from postoperative complications. Preoperative recognition of frailty may serve as a useful adjunct for risk assessment.

Comparative Study Observational Study
Carotid endarterectomy for asymptomatic carotid stenosis in the very elderly.
The indication for carotid endarterectomy (CEA) is uncertain in patients with asymptomatic severe (≥60% luminal narrowing according to the North American Symptomatic Carotid Endarterectomy Trial criteria) carotid stenosis (ASCS), especially in the very elderly, because current evidence suggests that the risk of future stroke has been dropping in the past two decades owing to the recent advances in medical therapy. The aim of this observational study was to compare early and late outcomes in patients ≥80 years old with ASCS treated with CEA plus best medical treatment (BMT) or with BMT alone. ⋯ CEA is a safe, effective, and durable treatment for ASCS in patients aged 80 years or more, carrying an insignificant perioperative stroke/death risk. CEA associated with BMT seems preferable to BMT alone in preventing the risk of ipsilateral ischemic events, without translating into a longer survival.

Comparative Study
Contemporary comparison of aortic arch repair by endovascular and open surgical reconstructions.
This study analyzed total aortic arch reconstruction in a contemporary comparison of current open and endovascular repair. ⋯ Despite the older age and a higher comorbidity profile in patients with challenging aortic arch disease suitable and selected for endovascular arch repair, no significant differences were detected in perioperative and 4-year outcomes compared with the younger patients undergoing open arch total repair. An endovascular approach might also be a valid alternative to open surgery in average-risk patients with aortic arch diseases requiring 0 to 1 landing zones, when morphologically feasible. However, larger concurrent comparison and longer follow-up are needed to confirm this hypothesis.

A surgeon, Dr A. Droit, has been following a 97-year-old male with a type IV thoracoabdominal aneurysm, which became symptomatic this morning and is leaking. The patient is frail but active with no important comorbidities. ⋯ Dr Droit knows an anesthesiologist who handles high-risk patients at another hospital in the medical center. The patient has worsened over the last hour, is becoming more unstable, and is unable to respond but his wife wishes to consent for surgery. What should Dr Droit do?
