Multicenter Study Observational Study
Preoperative hemoglobin A1c levels and increased risk of adverse limb events in diabetic patients undergoing infrainguinal lower extremity bypass surgery in the Vascular Quality Initiative.
The impact of preoperative glycemic control on the risk of adverse perioperative outcomes in diabetic patients undergoing lower extremity bypass (LEB) surgery is not well-understood. We determined whether higher preoperative hemoglobin A1c (HbA1c) levels are associated with an increased risk of major adverse limb events, major adverse cardiovascular events, and mortality in diabetic patients undergoing infrainguinal LEB. ⋯ Poor preoperative glycemic control in diabetic individuals undergoing infrainguinal LEB, particularly in those without critical limb ischemia, is associated with an increased risk of in-hospital limb events. Further study should evaluate whether improved efforts to identify individuals with poorly controlled diabetes and subsequent interventions to better optimize glycemic control during the preoperative period improve limb outcomes after LEB.

The aim of this retrospective analysis was to evaluate the outcomes of physician-modified double fenestrated stent grafts for total endovascular aortic arch repair: one proximal large fenestration for the brachiocephalic trunk and the left common carotid artery and one distal fenestration for the left subclavian artery (LSA). ⋯ Double homemade fenestrated TEVAR is both feasible and effective for maintaining the patency of the supra-aortic trunks and allows total endovascular aortic arch repair. Durability concerns will need to be assessed in additional studies with long-term follow-up.

In treating concomitant carotid and coronary disease, some recommend staged carotid endarterectomy (CEA) and coronary artery bypass grafting, whereas others favor the combined approach (CCAB). Pressure to reduce surgical variation and to improve quality is real, yet little is known about how geographic practice differences affect outcomes. Using the Vascular Quality Initiative (VQI), this study evaluated regional variation in use and outcomes of CCAB. ⋯ Significant variation exists across VQI centers in the use of CCAB. Despite differences in volume and practices, regional perioperative outcomes are similar. UNI is the most commonly used indication and has lower stroke rates relative to SYMP and BIL. CCAB is performed well across the United States, but most patients fall outside of Society for Vascular Surgery guidelines.

An endovascular-first approach is usually recommended in femoropopliteal occlusive disease. However, despite high technical success, plain old balloon angioplasty (POBA) is burdened with high restenosis rates. To reduce this phenomenon, local delivery of drugs has been proposed by way of drug-coated balloons (DCBs). Our goal was to review the evidence for the use of DCBs in the management of femoropopliteal disease and to determine whether it is associated with improved outcomes compared with POBA. ⋯ DCB angioplasty is an effective treatment associated with high procedural success. In a meta-analysis of industry-sponsored trials, it consistently reduced late lumen loss, binary restenosis, and target lesion revascularization compared with POBA alone in the treatment of femoropopliteal disease. Further independent, non-industry-sponsored RCTs are necessary to better delineate the role of DCBs in the treatment of infrainguinal occlusive disease.

Arteriovenous fistulas for patients undergoing hemodialysis (HD) are at high risk of stenosis. Despite conventional balloon angioplasty (CBA), restenosis rates are high. The use of a drug-coated balloon (DCB) may offer an alternative to reduce restenosis. ⋯ DCB angioplasty appears to be a better and safe alternative to CBA in treating patients with HD stenosis in terms of 6- and 12-month primary patency. However, a larger trial is warranted to establish these findings.
