Randomized Controlled Trial Multicenter Study Comparative Study
Anesthetic type and risk of myocardial infarction after carotid endarterectomy in the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST).
Carotid endarterectomy (CEA) is usually performed under general anesthesia (GA), although some advocate regional anesthesia (RA) to reduce hemodynamic instability and allow neurologic monitoring and selective shunting. RA does not reduce risk of periprocedural stroke or death, although some series show a reduction in myocardial infarction (MI). We investigated the association of anesthesia type and periprocedural MI among patients receiving GA or RA for CEA and patients undergoing carotid artery stenting (CAS) in the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST). ⋯ Patients in CREST undergoing CEA-RA had a similar risk of periprocedural MI as those undergoing CAS, whereas the risk for CEA-GA was twice that compared with patients undergoing CAS. Nevertheless, because periprocedural MI is one of the few variables favoring CAS over CEA and has been associated with decreased long-term survival, RA should be seriously considered for patients undergoing CEA.

Review Practice Guideline
Reporting standards of the Society for Vascular Surgery for endovascular treatment of chronic lower extremity peripheral artery disease.
Peripheral arterial disease (PAD) represents a spectrum from asymptomatic stenosis to limb-threatening ischemia. The last decade has seen a tremendous increase in the variety of endovascular devices and techniques to treat occlusive disease. Like many evolving technologies, the literature surrounding therapy for endovascular arterial disease consists of mixed-quality manuscripts without clear standardization. ⋯ We have also made recommendations based on current literature and have attempted to acknowledge shortcomings and areas for future research. The various sections contain summaries of required reporting standards and should serve as a guide for the design of clinical trials and as reference for journal editors and reviewers when considering scientific work pertaining to endovascular therapy for chronic lower extremity arterial disease. An Appendix is provided with commonly used abbreviations in this document.

Review Practice Guideline
Reporting standards of the Society for Vascular Surgery for endovascular treatment of chronic lower extremity peripheral artery disease: Executive summary.
Recommended reporting standards for lower extremity ischemia were last published by the Society for Vascular Surgery in 1997. Since that time, there has been a proliferation of endovascular therapies for the treatment of chronic peripheral arterial disease. The purpose of this document is to clarify and update these standards, specifically for reports on endovascular treatment. The document is divided into sections: Claudication Reporting, Critical Limb Ischemia Reporting, Preintervention Assessment and Nonanatomic Treatment, Intervention, Outcome Measures - Procedural, Outcome Measures - Disease Specific, and Complications.

Comparative Study
Influence of gender and use of regional anesthesia on carotid endarterectomy outcomes.
Carotid endarterectomy (CEA) is the most commonly performed surgical procedure to reduce the risk of stroke. The operation may be performed under general anesthesia (GA) or regional anesthesia (RA). We used a national database to determine how postoperative outcomes were influenced by gender and type of anesthesia used. ⋯ On adjusted multivariate analysis, there is no statistically significant difference in postoperative incidence of MI or stroke between men and women undergoing CEA. Use of RA vs GA did not affect this finding. Furthermore, there was no correlation between gender and the type of anesthesia chosen. Women, however, experienced decreased operative times and increased length of stay regardless of anesthesia type.

The Model for End-Stage Liver Disease (MELD) score has traditionally been used to prioritize liver transplantation. However, its use has been extended to predict overall and postoperative outcomes in patients with hepatic and renal dysfunction. Our objective was to use the MELD score to predict outcomes in patients undergoing lower extremity bypass. ⋯ An elevated MELD score places patients undergoing infrainguinal bypass at higher risk of perioperative morbidity and mortality. This provides an evidence base for risk stratification and informed consent for these patients. Alternative treatment may be considered in these patients; however, the overall morbidity and mortality rates may still be acceptable, even in high-risk patients.
