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.

Endovascular surgery has revolutionized the treatment of aortic aneurysms; however, these improvements have come at the cost of increased radiation and contrast exposure, particularly for more complex procedures. Three-dimensional (3D) fusion computed tomography (CT) imaging is a new technology that may facilitate these repairs. The purpose of this analysis was to determine the effect of using intraoperative 3D fusion CT on the performance of fenestrated endovascular aortic repair (FEVAR). ⋯ These results demonstrate that use of intraoperative 3D fusion CT imaging during FEVAR can significantly decrease radiation exposure, procedure time, and contrast usage, which may also decrease the overall physiologic impact of the repair.

Endovascular robotics systems, now approved for clinical use in the United States and Europe, are seeing rapid growth in interest. Determining who has sufficient expertise for safe and effective clinical use remains elusive. Our aim was to analyze performance on a robotic platform to determine what defines an expert user. ⋯ This study demonstrates that motion-based metrics can differentiate novice from trained users of flexible robotics systems for basic endovascular tasks. Efficiency of catheter movement, consistency of performance, and learning curves may help identify users who are sufficiently trained for safe clinical use of the system. This work will help identify the learning curve and specific movements that translate to expert robotic navigation.

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.

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?
