Multicenter Study Comparative Study
Aortic Curvature Remodeling after Thoracic Endovascular Aortic Repair: Assessing Device Conformability, Using Image Vector Analysis.
Aortic arch curvature can be straightened by endograft placement. However, different measurement methods with dissimilar follow-up and endografts have been published. The aim of this study was to corroborate, for the first time, the pliability of the Conformable Gore TAG Thoracic Endoprosthesis (W.L. Gore and Associates, Flagstaff, AZ, USA) into the aortic arch, using different image vector analysis. ⋯ Conformable Gore TAG Thoracic Endoprosthesis thoracic endograft showed a good pliability into the aortic arch and proximal thoracic aorta, with minimal changes in the aortic curvature after endograft placement in the short-term follow-up (up to six months). In addition, final endograft length into outer aortic curvature is highly predictable.

Meta Analysis
Extracorporeal Shockwave Therapy for Diabetic Foot Ulcers: A Systematic Review and Meta-Analysis.
Diabetes mellitus is one of the most common chronic diseases worldwide. Diabetic foot ulcers (DFUs) occur in over 10% of diabetic patients and are associated with high morbidity. Clinical trials have shown benefit from extracorporeal shockwave therapy (ESWT) in a DFU healing. This systematic review aims to assess the currently available evidence examining the efficacy of ESWT on healing of DFU. ⋯ This systematic review concludes that ESWT has the potential to improve healing in DFUs, although there is, as yet, insufficient evidence to justify its use in routine clinical practice. The meta-analysis has a high risk of bias and is unlikely to reflect true effect size because of problematic risk of bias in included studies. This review highlights the variable quality of methodology of trials and dosing of shockwave therapy and the need for robust adequately powered research into this promising therapy.

According to the Center for Disease Control and Prevention, trauma is the leading cause of death in children aged >1 year in the United States (US). Although vascular injuries occur in only 0.6-1% of pediatric patients with trauma, they are a major mortality contributor. This study aims to examine epidemiology and outcomes after pediatric vascular injuries (PedVIs) in the US. ⋯ We observed a significant decrease in the overall severity of injury and in-hospital mortality concurrent with the observation of a significant decrease in the rates of pediatric MVC vascular injuries. Public health policies directed toward firearm safety may further decrease PedVIs and mortality among this vulnerable population.

The incidence of cardiovascular and limb-specific adverse outcomes is higher in peripheral arterial disease (PAD) patients with diabetes. Metformin is associated with improved cardiovascular morbidity and mortality. However, the effect of metformin on limb-specific outcomes is unclear. The objective of this study was to assess the effect of metformin on outcomes after intervention for PAD. ⋯ Metformin is associated with improved survival and decreased incidence of adverse cardiac events in PAD patients. However, it did not have an impact on patency or LS rates after open and endovascular interventions. LS was worse in diabetic patients primarily treated with insulin.

TEVAR is the preferred way of treatment of complicated type B aortic dissection. The purpose of the study was to assess the impact of TEVAR on aortic remodeling in the thoracic and abdominal segment in long-term follow-up. ⋯ TEVAR for complicated acute aortic type B dissection is a safe and effective method of protecting thoracic aorta. The procedure was effective in majority of patients, and in 80% of the cases, there was no need for additional distal aortic coverage. The abdominal aorta is relatively stable over a long period of observation in complicated type B aortic dissection.
