Frailty syndrome is an established predictor of adverse outcomes after carotid surgery. Recently, a modified 5-factor National Surgical Quality Improvement Program frailty index has been used; however, its utility in vascular procedures is unclear. The aim of our study was to compare the 5-factor modified frailty index (mFI-5) with the 11-factor modified frailty index (mFI-11) regarding value and predictive ability for mortality, postoperative infection, and unplanned 30-day readmission. ⋯ The mFI-5 and mFI-11 are equally effective predictors of postoperative outcomes in patients undergoing carotid endarterectomy. mFI-5 is a strong predictor of postoperative complications, mortality, and 30-day readmission.

Endovascular aortic aneurysm repair (EVR) has a major financial impact on health care systems. We characterized reimbursement for index EVR hospitalizations among Medicare beneficiaries having surgery at Vascular Quality Initiative (VQI) centers. ⋯ Reimbursement for EVR declined between 2003 and 2015. We identified preoperative clinical factors independently associated with reimbursement and quantified the impact of different postoperative complications on reimbursement. More work is needed to better understand the substantial variation observed in reimbursement at the center level.

Whether remote ischemic preconditioning (RIPC), through several cycles of ischemia-reperfusion, can generate endogenous protective substances to protect patients undergoing elective major vascular surgery remains unclear. The results derived from many randomized controlled trials (RCTs) have been discrepant. ⋯ There is no prominent evidence to support the hypothesis that RIPC can provide perioperative protection to patients undergoing elective major vascular surgery. Therefore, the routine use of RIPC to reduce the incidence of perioperative complications of these operations may not be recommended.

Multiple studies have demonstrated the benefits of creating arteriovenous fistulas (AVFs) under regional anesthesia. This is most likely because of the avoidance of hemodynamic instability and stress response of general anesthesia, as well as the sympathectomy associated with brachial plexus blockade. As vein diameter is the major limiting factor for primary AVF creation and maturation, our aim is to investigate if the vasodilation that accompanies regional anesthesia leads to improved patency and maturation rate of autologous AVF and improved patency of arteriovenous graft (AVG) compared with those placed under general anesthesia. ⋯ This study showed possible improvements in failure rates for vascular accesses placed under regional anesthesia compared with those placed under general anesthesia. In addition, we showed an impact of regional anesthesia on the surgical plan by transitioning from a planned AVG to an AVF, intraoperatively. Giving patients with originally inadequate vein diameter the chance to have the preferred hemodialysis access method by simply switching anesthesia type could reduce the number of grafts placed in favor of fistulas.

Multicenter Study Comparative Study
Operative Treatment and Clinical Outcomes in Peripheral Vascular Trauma: The Combined Experience of Two Centers in the Endovascular Era.
Arterial traumas of the extremities are quite rare in civilian records; nevertheless, patients with trauma of limbs are admitted daily in emergency departments worldwide. The up-to-date information about epidemiology and treatment (open vs. endovascular surgery) comes from war records and it is not always easy getting data on mortality and morbidity in these patients. The aim of this study is to analyze the approach (open or endovascular) and the outcome of patients with vascular trauma of upper limbs (from the subclavian artery) and/or lower limbs (distal to the inguinal ligament), in the greater Milan area. ⋯ Isolated arterial trauma of the extremities are rare, usually they occur in the setting of multiple trauma patients. Despite progresses in surgical techniques, there are still controversies in diagnosis and treatment of these patients. We treated most cases with open surgery (n = 46), choosing endovascular approach (embolization performed mainly by interventional radiologists) in difficult anatomic districts. We believe that, during decision-making of the surgical strategy, it is important to consider the anatomical site of lesions and the general condition of the patients. Moreover, in case of multiple trauma, we suggest a multidisciplinary approach to provide the best medical care to the victims.
