Comparative Study
The effect of anesthesia type on major lower extremity amputation in functionally impaired elderly patients.
Patients undergoing major lower extremity amputations are at risk for a wide variety of perioperative complications. Elderly patients with any functional impairment have been shown to be at high risk for these adverse events. Our goal was to determine the association between the type of anesthesia-general anesthesia (GA) and regional/spinal anesthesia (RA)-on perioperative outcomes after lower extremity amputation in these elderly and functionally impaired patients. ⋯ The mode of anesthesia, GA vs RA, did not have significant effect on perioperative outcomes after major lower extremity amputation in the functionally impaired geriatric population. These findings provide an evidence base that will allow surgeons, anesthesiologists, and patients to make an informed decision about anesthesia type for their procedure.

Multicenter Study
Renin-angiotensin-aldosterone-system inhibition is safe in the preoperative period surrounding carotid endarterectomy.
Discontinuation of angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) medications before surgery has been suggested because of the potentially deleterious effects of hypotension. We investigated the effect of preoperative ACEI and/or ARB use on early outcomes after carotid endarterectomy (CEA). ⋯ Preoperative ACEI and/or ARB use was associated with marginally increased use of IVBPmed for HTN but not for hypotension and was not associated with increased MACE, stroke, or death. On the basis of these metrics, the use of preoperative ACEI and/or ARB appears safe before CEA.

Endovascular repair of ruptured abdominal aortic aneurysms does not reduce later mortality compared with open repair.
Endovascular aneurysm repair (EVAR) of ruptured abdominal aortic aneurysms (RAAAs) reduces in-hospital mortality compared with open repair (OR), but it is unknown whether EVAR reduces long-term mortality. We hypothesized that EVAR of RAAA would independently reduce long-term mortality compared with OR. ⋯ EVAR does not independently reduce long-term mortality compared with OR. Patient comorbidities and indices of shock on admission are the primary independent determinants of long-term mortality. However, the lower early mortality observed in the Vascular Quality Initiative for patients selected to undergo EVAR of RAAA compared with patients selected for OR is sustained over time, suggesting that EVAR for RAAA is beneficial in appropriate candidates. Better elucidation of the key selection factors, including aneurysm anatomy, is needed to best select patients for EVAR and OR to reduce long-term mortality.

"Never events" refers to harmful hospital-acquired conditions that the Centers for Medicare and Medicaid Services identified in 2008 as largely preventable and that would no longer be reimbursed. Our goal was to identify the incidence, predictive factors, temporal trend, and associated consequences of never events after major open vascular surgery procedures. ⋯ Never events after major vascular surgery are associated with a number of perioperative factors and are predictive of increased charges, LOS, and mortality. Falls and catheter-based UTIs have increased in frequency since the Centers for Medicare and Medicaid Services announced that it would no longer reimburse for these complications. This study establishes baseline never event rates in the vascular surgery patient population and identifies high-risk patients to target for quality improvement.

Strategies to improve outcomes for patients with ruptured abdominal aortic aneurysm (rAAA) are becoming more evident. The aging population, however, continues to make the decision to intervene often difficult, especially given that traditional risk models do not reflect issues of aging and frailty. This study aimed to integrate measures of function alongside comorbidity- and frailty-specific factors to determine outcome. ⋯ This novel rAAA model incorporating function and comorbidity offers good predictive power for mortality. It is quick to calculate and may ultimately become helpful for both counseling and selection of patients and comparative audit at a time when outcome in patients with rAAA increasingly comes under the spotlight.
