Patients with abdominal aortic aneurysms (AAAs) who are surgical candidates have as many as three options: open surgery, endovascular surgery, or no surgery. As with all treatment decisions, informed patient preferences are critical. Decision support tools have the potential to better inform patients about the risks and benefits associated with each treatment option and to empower patients to participate meaningfully in the decision-making process. The objective of this study was to develop and pilot test a decision support tool for patients with AAAs. ⋯ Preliminary evidence suggests that use of an evidence-based AAA decision support tool is feasible and acceptable to patients, increases knowledge, and decreases decisional conflict. Widespread use of such a tool might improve the content and quality of informed consent for this difficult treatment decision.

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.

Multicenter Study
Long-term results of Talent endografts for endovascular abdominal aortic aneurysm repair.
Since the introduction of endovascular aneurysm repair (EVAR), long-term follow-up studies reporting single-device results are scarce. In this study, we focus on EVAR repair with the Talent stent graft (Medtronic, Santa Rosa, Calif). ⋯ Initially, technical success of endovascular aneurysm repair (EVAR) using the Talent endograft is high, with acceptable yearly risk for AAA-related mortality and conversion. However, a substantial amount of mainly endovascular reinterventions is necessary during long-term follow-up to achieve these results.

Comparative Study
The influence of polyvascular disease on the obesity paradox in vascular surgery patients.
Obesity is a risk factor for atherosclerosis, a polyvascular process associated with reduced survival. In nonvascular surgery populations, a paradox between body mass index (BMI) and survival is described. This paradox includes reduced survival in underweight patients, whereas overweight and obese patients have a survival benefit. No clear explanation for this paradox has been given. Therefore, we evaluated the presence of the obesity paradox in vascular surgery patients and the influence of polyvascular disease on the obesity paradox. ⋯ Overweight patients referred for vascular surgery were characterized by an increased incidence of polyvascular disease and required more extensive medical treatment for cardiovascular risk factors at discharge. Long-term follow-up showed a paradox of reduced mortality in overweight patients.
