Metabolic syndrome reduces the survival benefit of the obesity paradox after infrainguinal bypass.
Metabolic syndrome, having risen to epidemic proportions in the United States, is associated with future cardiovascular disease and mortality and increased postoperative complication rates. However, the impact of metabolic syndrome on outcomes after infrainguinal bypass surgery remains poorly defined. ⋯ Patients with metabolic syndrome are at an increased risk of postoperative complications after infrainguinal bypass. Despite increased morbidity, metabolic syndrome was not associated with inferior 30-day mortality, but did diminish the survival benefit of the obesity paradox.

While much has been written about multiple methods of neuromonitoring during carotid endarterectomy (CEA), there has been relatively little discussion of the use of triple monitoring via somatosensory evoked potentials (SEPs) and motor evoked potentials (MEPs) in conjunction with electroencephalography (EEG). Our objective was to evaluate the rate of detection and prevention of neurologic events by multinerve SEP, MEP, and EEG in patients undergoing CEA while under general anesthesia. ⋯ The ratio of shunting at 2.7% is equal to the lowest rates reported in the awake patient literature. Interestingly, the predicted synergy of multimodality monitoring cannot be directly attributed to an increased specificity resulting from the addition of SEP and MEP to EEG, because no patients had EEG changes. In addition, in today's cost-conscious world of health care, our results do not justify implementing this particular technique of neuromonitoring across the board-but it is apparent that the combination of these 3 modalities is both safe and effective with potential applications in symptomatic patients.

The aim of this study was to determine predictors of improved quality of life and claudication in patients undergoing spinal cord stimulation (SCS) for critical lower limb ischemia. ⋯ In our series of patients who underwent SCS, reduced delay between the onset of ulcer and SCS was associated with improved quality of life and walking distance. Larger series are required to confirm these data and to assess clinical implications.

Surgical and endovascular treatment of extracranial carotid artery aneurysms: early and long-term results of a single center.
To evaluate early and long-term results of surgical and endovascular therapy of extracranial carotid artery aneurysms. ⋯ Surgical treatment is feasible, with an acceptable rate of stroke and cranial nerve injuries, especially when the aneurysm is located on the common carotid artery and carotid bulb. Endovascular therapy is a fascinating option, with satisfactory early and long-term results, and should always be considered when treating aneurysms located in the distal internal carotid artery and when the patient is not a good candidate for open surgery.

Pseudoaneurysm of the internal mammary artery is an unusual complication of wounds to the chest. We report a case of a 41-year-old man who sustained a stab chest wound and posttraumatic pseudoaneurysm of the internal mammary artery, resulting in hemomediastinum and hemothorax. The patient was successfully treated using emergency endovascular coil embolization. Because this injury is extremely rare, the literature is reviewed, and several principles are suggested to improve the management.
