Objective: Based on data supporting a volume-outcome relationship in elective aortic aneurysm repair, the Society of Vascular Surgery (SVS) guidelines recommend that endovascular aortic repair (EVAR) be localized to centers that perform ≥10 operations annually and have a perioperative mortality and conversion-to-open rate of ≤2% and that open aortic repair (OAR) be localized to centers that perform ≥10 open aortic operations annually and have a perioperative mortality ≤5%.

Exosome characteristicsUltimately, only 24 patients (10 AAA and 14 control) had blood samples that were adequate for exosomal miRNA analyses. Nanoparticle tracking analysis revealed that Fraction 7’s average particle size in all of the samples ranged from 83.7 to 142.4 nanometers and the concentration of particles in this fraction ranged from 1.35x108 to 5.33x108.
