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.

The aim of this study is to evaluate the long-term survival and treatment-related outcome in patients treated with intra-arterial thrombolysis for acute lower limb ischemia. ⋯ The long-term patency after CDT is unfavorable, and additional procedures are needed to preserve adequate distal perfusion. Approximately 30% of the patients are alive at 10 years after the initial CDT. Increasing age and atrial fibrillation have a negative effect on the patients' survival.

Venous thoracic outlet syndrome (vTOS) is a rare disease with no defined guidelines regarding treatment. Patients with first rib resection with anterior scalenectomy (FRRS) often have residual subclavian vein stenosis. The aim of this study was to evaluate the use of intravascular ultrasound (IVUS) in the treatment of vTOS patients who have been surgically decompressed with FRRS. ⋯ These results suggest that IVUS detected greater levels of stenosis than venography, leading to more interventions. Just as IVUS being ideal for identifying occult iliac venous lesions, it may have a similar role in identifying venous lesions not evident on single-plane venography for postsurgical decompression in vTOS patients. Further studies may show this technique to increase the number of stenoses identified and improve long-term symptom relief.

Meta Analysis Comparative Study
Open versus Endovascular Repair of Descending Thoracic Aortic Aneurysm Disease: A Systematic Review and Meta-analysis.
The purpose of this study was to determine whether thoracic endovascular aortic repair reduces death and morbidity compared with open surgical repair for descending thoracic aortic disease. ⋯ The present meta-analysis shows that endovascular repair of thoracic aortic aneurysm gives better perioperative outcomes during inhospital stay although the 1- and 5-year mortality remains the same in both groups; but the long-term outcome is yet to be established. A long-term data and studies are required to give a better understanding of comparing these 2 techniques beyond 5 years of follow-up.

Endovascular aneurysm repair (EVAR) accounts for the majority of all abdominal aortic aneurysm (AAA) repairs in the United States. EVAR utilization in the aging population is increasing due to the minimally invasive nature of the procedure, the low associated perioperative morbidity, and early survival benefit over open repair. The objective of this study is to compare the outcomes of octogenarians after elective EVAR to their younger counterparts, a question that can be answered by a long-term, institutional data set. ⋯ Elective endovascular repair of AAA in octogenarians carries a higher risk of perioperative mortality but acceptable long-term outcomes. Appropriateness of elective EVAR in octogenarians should be answered based on this potential short-lived survival benefit, taking into account that advanced age should not be the sole basis of exclusion for otherwise suitable candidates for elective EVAR.
