Comparative Study
Regional anesthesia for carotid surgery: less intraoperative hypotension and vasopressor requirement.
Regional anesthesia (RA) is the gold standard of neuromonitoring during carotid endarterectomy (CEA). Recent data show that RA for CEA is associated with fewer postoperative complications. The aim of the present study was to assess hemodynamic stability and vasoactive drug use for CEA performed under RA versus general anesthesia (GA). ⋯ There was no significant difference between groups in hypotension or hypertension episodes seen in the postoperative recovery room. RA was associated with less hypotension and less vasopressor used during CEA compared to GA. The improved hemodynamic stability may account for the lower incidence of complications after CEA.

We assessed the long-term clinical outcome of 33 patients treated for arterial trauma of the upper extremity at the Regensburg University Medical Center between 1996 and 2004. Along with clinical parameters, the Disabilities of Arm, Shoulder, and Hand (DASH) score and the Short Form-36 Health Survey (SF-36) score of each patient were collected at the time of follow-up. Findings of the clinical assessment were compared to results obtained with the DASH score and the SF-36 questionnaire. ⋯ Both the DASH and the SF-36 scores correlated with the clinical assessment of the severity of functional deficits. Upper extremity vascular trauma is almost always associated with severe concomitant orthopedic and/or neural injuries. The involvement of the brachial plexus and the peripheral nerves of the upper extremity is a predictor of worse long-term functional outcome.

Review Meta Analysis
What is the evidence on efficacy of spinal cord stimulation in (subgroups of) patients with critical limb ischemia?
The use of spinal cord stimulation (SCS) has been advocated for the management of ischemic pain and the prevention of amputations in patients with inoperable critical limb ischemia (CLI), although data on benefit are conflicting. Several reports described apparently differential treatment effects in subgroups. The purpose of this study was to analyze the data on the efficacy of SCS and to clarify preselection issues. ⋯ The analysis did not indicate a subgroup of patients who might specifically be helped by SCS. Meta-analysis including all randomized data shows insufficient evidence for higher efficacy of SCS treatment compared with best medical treatment alone. Although some factors provide prognostic information as to the risk of amputation in patients with CLI, there are no data supporting a more favorable treatment effect in any group.

Carotid artery stenting (CAS) for restenosis (RS) after carotid endarterectomy (CEA) is presumed to have fewer complications than CAS for primary atherosclerotic (PA) lesions. It has been proposed that interventionalists may limit themselves to CAS for RS initially, while they gain additional experience during their learning curve. However, there are few studies objectively comparing the outcomes of the two groups of patients to substantiate this assumption. ⋯ CAS for RS must therefore not be considered a low-risk procedure. Technical proficiency for CAS must be equivalent regardless of the etiology of the stenosis. These observations also underscore the need for appropriate patient selection and close follow-up of all patients undergoing CAS.

The aim of this study was to determine whether vascular patients are becoming progressively more obese and whether morbid obesity affects outcomes from vascular surgery. Data for the index vascular procedures of infrainguinal bypass, carotid endarterectomy, and abdominal aortic aneurysm (AAA) repair were collected in a computer database for 1996-2006. Body mass index (BMI) was stratified into <18.5 kg/m2 as underweight, >35 kg/m2 as morbidly obese, and other as control (18.5 < BMI < 35). ⋯ Procedures performed on morbidly obese subjects take longer, and these patients have higher rates of infectious complications. This is mainly attributable to AAA. This did not translate into poorer final outcomes in this study, although significant differences might emerge from a larger sample.
