Randomized Controlled Trial
Vacuum-assisted wound closure versus alginate for the treatment of deep perivascular wound infections in the groin after vascular surgery.
Vacuum-assisted wound closure (VAC) therapy may heal wounds faster than conventional dressings after surgical debridement of perivascular groin infections after vascular surgery. ⋯ VAC achieves faster healing than alginate therapy after wound debridement for deep perivascular wound infections in the groin after vascular surgery. This finding does not allow further inclusion of patients from an ethical point of view, and this study was, therefore, stopped prematurely.

Multicenter Study Comparative Study
Carotid stenting versus endarterectomy in patients undergoing reintervention after prior carotid endarterectomy.
Outcomes for patients undergoing intervention for restenosis after prior ipsilateral carotid endarterectomy (CEA) in the era of carotid angioplasty and stenting (CAS) are unclear. We compared perioperative results and durability of CAS vs CEA in patients with symptomatic or asymptomatic restenosis after prior CEA and investigated the risk of reintervention compared with primary procedures. ⋯ In the VSGNE, CEA and CAS showed statistically equivalent outcomes in asymptomatic and symptomatic patients treated for restenosis after prior ipsilateral CEA. However, regardless of symptom status, the risk of reintervention was increased compared with patients undergoing primary CEA.

Previous studies have shown that female gender is associated with increased morbidity and mortality after endovascular abdominal aortic aneurysm repair. The goal of this study was to assess the effect of gender on 30-day outcomes after thoracic endovascular aortic aneurysm repair (TEVAR) using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. ⋯ Thirty-day unadjusted mortality after TEVAR for nonruptured thoracic aortic aneurysms is increased in women compared with men, but this univariate finding did not persist after risk adjustment. Multivariable analysis showed need for iliac artery exposure, age, and emergency surgery were independently associated with higher mortality rates. These results suggest a need for decreased device delivery size and improvements in endovascular technology.

Clinical Trial
Hypogastric and subclavian artery patency affects onset and recovery of spinal cord ischemia associated with aortic endografting.
Spinal cord ischemia (SCI) is a devastating complication associated with aortic aneurysm repair. The aim of the current study was to evaluate factors affecting outcomes from SCI associated with endovascular aortic aneurysm repair. ⋯ SCI continues to complicate aortic surgery despite the advent of endovascular therapy. Occlusion of a single collateral bed is associated with an increased risk for immediate onset of SCI and lack of recovery. These factors are harbingers of poor outcomes and increased short-term mortality. This may be prevented by preserving collateral bed patency in patients undergoing extensive endovascular procedures.
