Comparative Study
Arterial cutdown reduces complications after brachial access for peripheral vascular intervention.
Factors influencing risk for brachial access site complications after peripheral vascular intervention are poorly understood. We queried the Society for Vascular Surgery Vascular Quality Initiative to identify unique demographic and technical risks for such complications. ⋯ Brachial access for peripheral vascular intervention carries significantly increased risks for access site occlusion or hematoma formation. Arterial cutdown and smaller sheath diameters are associated with lower complication rates and thus should be considered when arm access is required.

The objective of this study was to develop a surgical site infection (SSI) prediction score for risk assessment before elective vascular surgery. ⋯ We developed an SSI risk score based on noninvasive preoperative variables with acceptable discrimination and calibration. This tool needs prospective and external validation.

Observational Study
Increased homocysteine and lipoprotein(a) levels highlight systemic atherosclerotic burden in patients with a history of acute coronary syndromes.
Strong evidence supports an association between high levels of homocysteine (Hcy) and lipoprotein(a) [Lp(a)] and an increased rate of ischemic vascular events. ⋯ The addition of evaluation of Hcy ≥15 μmol/L and Lp(a) ≥500 mg/L to the traditional CRF count does improve detection of systemic atherosclerotic burden of patients with acute coronary syndrome and can offer a new opportunity to optimize secondary prevention.

This study reports our initial experience with the Gore Hybrid Vascular Graft (GHVG; W. L. Gore & Associates, Flagstaff, Ariz) for staged hybrid open renovisceral debranching and endovascular aneurysm repair in patients affected by thoracoabdominal aortic aneurysms and pararenal abdominal aortic aneurysms (PAAAs). ⋯ This limited series extracted from a more consistent hybrid procedure experience showed a mortality rate similar to most recent reports. Technical feasibility and the short-term patency rate of the GHVG for renovisceral debranching during staged hybrid open and endovascular procedures were satisfactory. Use of GHVGs may represent a useful revascularization adjunct to minimize visceral ischemia in these challenging patients.

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.
