Comparative Study Observational Study
Six-minute walk test closely correlates to "real-life" outdoor walking capacity and quality of life in patients with intermittent claudication.
We used outdoor walking distance measured during 40 minutes as "real-life" outdoor walking capacity in 49 patients with intermittent claudication (IC). The outdoor walking distance was measured by a global positioning system application for a smartphone. The relationships of self-reported maximum walking distance (SR-MWD), the MWD on a graded treadmill test, and the 6-minute maximum walk distance (6MWD) vs outdoors walking capacity were investigated. Also studied were the associations of SR-MWD, MWD, and 6MWD with health-related quality of life assessed with the disease-specific instrument the Vascular Quality of Life Questionnaire (VascuQoL). ⋯ The distance walked during the 6-minute walk test is closely correlated to outdoor walking capacity and health-related quality of life in IC patients. Our data support the use of 6MWD for routine clinical evaluation of walking capacity in IC patients.

Comparative Study
Observation and surgery are associated with low risk of amputation for blunt brachial artery injury in pediatric patients.
The ideal treatment for blunt brachial artery (BBA) injury in pediatric patients is controversial. We compared outcomes of surgical and nonsurgical management of BBA injury using the National Trauma Data Bank. ⋯ Despite slightly lower adverse outcomes, arterial surgery does not appear to confer a significant advantage over nonoperative treatment in pediatric patients with BBA injury. In patients younger than 6 years, both modalities appear to be equality effective.

Late thoracic aneurysms develop in 5% to 12% of patients having undergone open repair for coarctation of the aorta (CoA). We report our early results for thoracic endovascular aortic repair for pseudoaneurysms after CoA repair. ⋯ In this cohort, new-generation stent grafts have good early clinical and radiologic outcomes, avoiding the need for redo open surgery. Management of the LSCA can be tailored to individual patients with new stent graft technology. Long-term follow-up of these patients is crucial to understanding whether endovascular management of this cohort is acceptable.
