Endovascular repair of complex aortic aneurysms (CAAs) can be performed in high-risk individuals, yet is still associated with significant morbidity, including spinal cord ischemia, cardiac complications, and death. This analysis was undertaken to better define the cardiac risk for CAA. ⋯ Endovascular repair of CAA can be performed in high-risk individuals but is associated with significant cardiac risk. It remains difficult to risk stratify patients using preoperative stress testing. Echo evaluation may help to identify patients who may be more likely to develop ventricular arrhythmias in the postoperative period and thus warrant closer monitoring. Postoperative troponin monitoring of all patients undergoing repair of CAA is warranted given the overall risk of MI.

Phlegmasia cerulea dolens is a rare but serious complication of deep venous thrombosis, which can lead to arterial compromise, tissue ischemia, and gangrene. It typically presents in an elderly population often with coexistent malignancy. ⋯ Pharmacologic and mechanical interventions as described in the adult population were utilized. This case demonstrates that an aggressive, multimodal approach to phlegmasia cerulea dolens can be employed in the pediatric population and result in successful limb salvage.

To evaluate results of carotid endarterectomy (CEA) in diabetic patients in a large single-center experience. ⋯ In our experience, the presence of diabetes mellitus increases three-fold the risk of perioperative death after CEA, while there are no differences with nondiabetics in terms of perioperative stroke. However, the rate of stroke and death at 30 days still remains below the recommended standards. During follow-up, this difference becomes negligible, and results are fairly similar to those obtained in nondiabetics. Particular attention should be paid to patients undergoing intervention under general anesthesia, who seem to represent a subgroup of diabetics at higher perioperative risk, suggesting neurologic monitoring should be used when possible.

Aortic injury is the second leading cause of death in trauma. Thoracic endovascular aortic repair (TEVAR) has recently been applied to traumatic thoracic aortic injuries (TTAIs) as a minimally invasive alternative to open surgery. We sought to determine the impact of TEVAR on national trends in the management of TTAI. ⋯ TEVAR has replaced open repair as the primary operative treatment for TTAI and has extended operative treatment to those patients not previously considered candidates for repair. Increased utilization of TEVAR is associated with improved overall mortality. There is no difference in mortality between TEVAR and open repair groups in our study, which likely reflects the multisystem nature of injury and greater preoperative risk in the TEVAR group.

Hospital quality in vascular surgery is often measured using mortality. We sought to determine whether adjusting mortality for statistical reliability changes hospital quality rankings for vascular surgery. ⋯ Adjusting mortality for reliability reduces statistical noise and provides more stable estimates of hospital quality. Reliability adjustment should be standard for comparing hospital quality.
