The objective of this study was to identify relationships among geographic access to care, vascular procedure volume, limb preservation, and survival in patients diagnosed with critical limb ischemia (CLI). ⋯ Rates of major amputation are inversely associated with distance from the index hospital, whereas rates of both major amputation and mortality are inversely associated with LER volume. Rates of major amputation and mortality are directly associated with LEA volume. We believe that unless it is otherwise contraindicated, these data support consideration for selective referral of CLI patients to high-volume centers for LER regardless of distance. Within the context of value-based health care delivery, policy supporting regionalization of CLI care into centers of excellence may improve outcomes for these patients.

Failure to rescue (FTR) is defined as the inability to rescue a patient from major perioperative complications, resulting in operative mortality. FTR is a known contributor to operative mortality after open abdominal aortic surgery. Understanding the causes of FTR is essential to designing interventions to improve perioperative outcomes. The objective of this study was to determine the relative contributions of hospital volume and safety-net burden (the proportion of uninsured and Medicaid-insured patients) to FTR. ⋯ After adjusting for patient- and hospital-level variables, including hospital volume, safety-net burden was an independent predictor of FTR after open aortic surgery. Future investigations should be aimed at better understanding the relationship between safety-net hospital burden and FTR to design interventions to improve outcomes after open abdominal aortic surgery.

The 2013 American College of Cardiology/American Heart Association lipid management guidelines recommend high-intensity statins for all patients ≤75 years old with chronic limb-threatening ischemia (CLTI) and moderate-intensity statins for CLTI patients >75 years old without contraindications or on dialysis, but these recommendations are based primarily on coronary and stroke data. We aimed to validate these guidelines in patients with CLTI and to assess current adherence to these recommendations. ⋯ Use of the recommended intensity of statin therapy in compliance with 2013 American College of Cardiology/American Heart Association lipid management guidelines is associated with significantly improved survival and lower MALE rate in patients undergoing revascularization for CLTI. Adherence to current guidelines is an appealing target for quality improvement.

Comparative Study Observational Study
Fenestrated endovascular aneurysm repair among octogenarians at high and standard risk for open repair.
Octogenarians with complex abdominal aortic aneurysms are at higher risk of death and morbidity after open repair. Fenestrated endovascular aneurysm repair (FEVAR) is an alternative to open repair for high-risk patients, such as octogenarians. The aim of this study was to evaluate perioperative and midterm outcomes of FEVAR among octogenarians at high and standard risk for open repair. ⋯ FEVAR is a safe and effective procedure in octogenarians at high and standard risk for open repair and those who are not eligible for standard endovascular aneurysm repair. Octogenarians have a similar technical success and low major adverse events similar to patients younger than 80 years.

Review Meta Analysis
Endarterectomy achieves lower stroke and death rates compared with stenting in patients with asymptomatic carotid stenosis.
It is currently unclear if carotid artery stenting (CAS) is as safe as carotid endarterectomy (CEA) for patients with significant asymptomatic stenosis. The aim of our study was to perform a systematic review and meta-analysis of trials comparing CAS with CEA. ⋯ Among patients with asymptomatic stenosis undergoing carotid intervention, there is moderate-quality evidence to suggest that CEA had significantly lower 30-day stroke and also stroke or death rates compared with CAS at the cost of higher CNI and nonsignificantly higher MI rates. The long-term efficacy of CEA in ipsilateral stroke prevention, taking into account perioperative stroke and death, was preserved during follow-up. There is an urgent need for high-quality research before a firm recommendation is made that CAS is inferior or not to CEA.
