Endovenous Laser Ablation of Varicose Veins Preserves Biological Properties of Vascular Endothelium and Modulates Proinflammatory Agent Profile More Favorably Than Classic Vein Stripping

Effect of serum from patients treated with CVS and EVLA on the number of population doublings (a), the activity of SA-β-Gal (b), and the production of reactive oxygen species (c) in endothelial cells. Endothelial cells were exposed to 20% sera for 72 h. Results (expressed as means ± SEM) derive from experiments performed with the sera from 8 (proliferation) or 12 (senescence, oxidative stress) patients per group. Asterisks indicate significant differences as compared with CVS. RFU: relative fluorescence units.
