Randomized Controlled Trial Comparative Study
Comparison of the effect of upper body-ergometry aerobic training vs treadmill training on central cardiorespiratory improvement and walking distance in patients with claudication.
Supervised treadmill-walking exercise programs have been proven to be a highly effective in improving walking distance in peripheral arterial disease (PAD) patients with lifestyle-limiting claudication. Limited information is available on the contributions of central cardiorespiratory functions for improving these patients' walking capacity with exercise training. ⋯ Improvements in cardiorespiratory function after arm-ergometry or treadmill-training were significantly associated with improvements in both PFWD and MWD, providing supporting evidence of systemic contributions to exercise training-related improvements in walking capacity seen in patients with claudication.

Randomized Controlled Trial Multicenter Study Comparative Study
A randomized controlled trial of endovascular aneurysm repair versus open surgery for abdominal aortic aneurysms in low- to moderate-risk patients.
Several studies, including three randomized controlled trials (RCTs), have shown that endovascular repair (EVAR) of abdominal aortic aneurysms (AAA) offered better early results than open surgical repair (OSR) but a similar medium-term to long-term mortality and a higher incidence of reinterventions. Thus, the role of EVAR, most notably in low-risk patients, remains debated. ⋯ In patients with low to intermediate risk factors, open repair of AAA is as safe as EVAR and remains a more durable option.

Randomized Controlled Trial Comparative Study
Variability and persistence of aspirin response in lower extremity peripheral arterial disease patients.
To determine the prevalence of poor response to aspirin (ASA) therapy over 12-month follow-up in patients with lower extremity peripheral arterial disease (PAD), and to compare the classification agreement among different ASA response assays. ⋯ Between 5% and 27.5% of PAD patients were Persistent PRs to ASA over 6- to 12-month follow-up using different platelet assays. Further, these commonly used platelet assays show weak agreement in determining poor response to aspirin.

Randomized Controlled Trial Comparative Study
A study to compare disease-specific quality of life with clinical anatomical and hemodynamic assessments in patients with varicose veins.
The wide variety of outcome measures to evaluate patients with varicose veins poses significant difficulties when comparing clinical trials. In addition, the relationship between different outcome measures is poorly understood. The aim of this study was to compare anatomical, hemodynamic, and clinical outcomes with disease-specific quality-of-life tools in patients undergoing treatment for varicose veins. ⋯ Both the AVVQ and SQOR-V questionnaire are sensitive and responsive disease-specific questionnaires, which correlate with generic and clinical outcomes to some extent. Anatomical and hemodynamic measurements correlated poorly with functional outcomes both preoperatively and following interventions.

Randomized Controlled Trial
Standardization is superior to traditional methods of teaching open vascular simulation.
Standardizing surgical skills teaching has been proposed as a method to rapidly attain technical competence. This study compared acquisition of vascular skills by standardized vs traditional teaching methods. ⋯ This study demonstrates the feasibility of open vascular simulation to assess the effect of differing teaching methods on performance outcome. Findings from this report suggest that for simulation training, standardized may be more effective than traditional methods of teaching. Transferability of simulator-acquired skills to the clinical setting will be required before open simulation can be unequivocally recommended as a major component of resident technical skill training.
