The aim of this systematic review is to describe the literature and assessment tools evaluating vascular surgical operative performance that could potentially be used for the assessment of educational outcomes applicable to the Milestone Project and the Next Accreditation System. ⋯ The literature describing assessment tools pertinent to vascular surgery is diverse. Existing assessment tools may be relevant to individual technical skill acquisition assessment; however, an operative assessment tool relevant to vascular/endovascular surgery and generalizable to the wide spectrum of technical and nontechnical skills pertinent to vascular surgery needs to be developed, validated, and implemented to allow the practical assessment of resident readiness to operate in an unsupervised setting.

Observational Study
Clinical characteristics associated with readmission among patients undergoing vascular surgery.
Readmission after a vascular surgery intervention is frequent, costly, and often considered preventable. Vascular surgery outcomes have recently been scrutinized by Medicare because of the high rates of readmission. We determined patient and clinical characteristics associated with readmission in a cohort of vascular surgery patients. ⋯ To reduce readmission rates effectively, institutions must identify high-risk patients. Efforts should focus on subgroups undergoing selected interventions (amputations, lower extremity revascularization), those with urgent admissions, and patients with extended hospital stays. Patients in need of postacute care upon discharge are especially prone to readmission, requiring special attention to discharge planning and coordination of postdischarge care. By focusing on subgroups at risk for readmission, preventative resources can be efficiently targeted.

Readmission is associated with high mortality, morbidity, and cost. We used the American College of Surgeons National Surgery Quality Improvement Program (ACS-NSQIP) to determine risk factors for readmission after lower extremity bypass (LEB). ⋯ Readmissions are common after LEB. Optimization of select chronic conditions, closer follow-up of patients in poor health and those who required return to the operating room, and early detection of surgical site infections may improve readmission rates. Our finding that 25% of readmissions after LEB are not procedure related informs the broader discussion of how a readmission penalty affects vascular surgery in particular.

Comparative Study Observational Study
Preoperative smoking is associated with early graft failure after infrainguinal bypass surgery.
Smoking has been implicated as the single most important risk factor for the development of peripheral arterial disease. Whereas previous studies have found poor long-term outcomes in smokers undergoing lower extremity bypass, there is a lack of consistent reports describing the effects of persistent tobacco abuse on early outcomes after infrainguinal bypass. ⋯ Although nonsmokers were significantly older, had more comorbidities, and required more distal revascularization, active smokers still had an increased risk for development of early graft failure. These results stress the need for immediate smoking cessation before lower extremity bypass. Further research is warranted to determine an optimal period of abstinence among smokers with peripheral arterial disease to reduce their risk for early graft failure.

To analyze biomechanical, histologic, and histochemical properties of anterior fragments of abdominal aortic aneurysms (AAA) and to correlate them with the maximum transverse diameter (MTD) and symptoms associated to the aneurysms. ⋯ The fragments of the anterior midsection from larger aneurysms were more resistant than those from smaller abdominal aortic aneurysms, with no tissue properties that could explain this phenomenon in the histologic or histochemical analyses. Larger aneurysms, at least in this place may be stronger than smaller aneurysms. It could point toward regional differences (heterogeneity, localized pathologies) as an important player in aneurysm rupture. Uniaxial strain tests are an important tool for the comprehension of a complex behavior such as that from an aneurysmal aortic wall. However, these tests still have limitations in providing information that would allow the calculation of the risk of rupture for abdominal aortic aneurysms.
