Randomized Controlled Trial
Effects of a long-term exercise program on lower limb mobility, physiological responses, walking performance, and physical activity levels in patients with peripheral arterial disease.
The purpose of the study was to examine the effects of a 12-month exercise program on lower limb mobility (temporal-spatial gait parameters and gait kinematics), walking performance, peak physiological responses, and physical activity levels in individuals with symptoms of intermittent claudication due to peripheral arterial disease (PAD-IC). ⋯ The results of this study confirm that a 12-month supervised exercise program will result in improved walking performance, but does not have an impact on lower limb mobility, peak physiological responses, or physical activity levels of PAD-IC patients.

Informed consent discussions for elective abdominal aortic aneurysm (AAA) repair should reflect appropriate risks of the open or endovascular repair (EVAR), but few guidelines exist describing what surgeons should discuss. This study examines expert opinion regarding what constitutes informed consent. ⋯ This is the first study of the practice of informed consent for AAA repair. The only risk that the vast majority of surgeons agreed should be included in informed consent for AAA repair was mortality. Significant variation exists regarding whether other complications should be discussed and what complication rates should be quoted. Surgeon characteristics may influence how risks are presented to patients. Further efforts are needed to develop guidelines to ensure consistent communication of appropriate risk during informed consent for AAA repair.

Endovascular repair (EVR) is emerging as first-line treatment for patients with superior vena cava (SVC) syndrome of benign etiology, but data on its durability remain scarce. The aims of this study were to assess the efficacy and durability of EVR and compare results of EVR with open surgical reconstruction (OSR). ⋯ OSR of benign SVC syndrome is effective, with durable long-term relief from symptoms. EVR is less invasive but equally effective in the mid-term, albeit at the cost of multiple secondary interventions, and is an appropriate primary treatment for benign SVC syndrome. OSR remains an excellent choice for patients who are not suitable for EVR or in whom the EVR fails.

Prospective validation of prognostic scoring systems for ruptured abdominal aortic aneurysm (AAA) is lacking. This study assesses the validity of three established risk scores and a new prognostic index. ⋯ Prospective validation shows that the Hardman Index, GAS, and V-POSSUM and RAAA-POSSUM scores do not perform well as predictors for death after ruptured AAA. The ERAS accurately stratifies perioperative risk but requires further validation.
