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.

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.

Comparative Study
No major difference in outcomes for endovascular aneurysm repair stent grafts placed outside of instructions for use.
Studies have shown that a sizable percentage of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAAs) is performed outside the instructions for use (IFU). We report our long-term outcomes after EVAR with respect to device-specific IFU. ⋯ Despite most EVAR patients being treated outside of IFU, there was no difference in outcomes with respect to all-cause mortality or aneurysm-related mortality. In addition, with the exception of perioperative blood transfusions, there was no association between IFU adherence and late-onset rupture, need for reintervention, rates of endoleak, aneurysm sac enlargement, or most other major complications.

Comparative Study Clinical Trial
Low-profile versus standard-profile multibranched thoracoabdominal aortic stent grafts.
This study compared midterm results using low-profile stent grafts (LPSGs; 18F) and standard-profile stent grafts (SPSGs; 22F-24F) for endovascular pararenal and thoracoabdominal aortic aneurysm (TAAA) repair. ⋯ LPSGs had similar safety profile and midterm outcomes compared with the SPSGs for treatment of pararenal and TAAA. The substitution of LPSGs for SPSGs lowered the number of patients who required conduit insertion to avoid access artery injury, especially in women, thereby reducing an otherwise striking gender difference.
