Analysis of the postoperative hemodynamic changes in varicose vein surgery related with small saphenous vein reflux

Purpose To evaluate the postoperative hemodynamic changes in varicose vein surgery related with SSV reflux using APG. Methods Totals of 181 limbs and 178 patients who underwent high ligation and stripping (HLS) (87 limbs), radiofrequency ablation (RFA) (43 limbs), or endovenous laser ablation (EVLA) (51 limbs) for SSV reflux from 1995 to 2022 were enrolled. We measured venous volume (VV), venous filling index (VFI), ejection fraction (EF), and residual volume fraction (RVF) preoperatively and at postoperative one and 6 months. Results Comparing preoperative results to those at postoperative 1 month, the reduction rates of VV, VFI, and RVF were 27, 53, and 31%, while EF increased by 18% (p < 0.001). Comparing preoperative and postoperative 6 month, the reduction rates of VV, VFI, and RVF were 27, 45, and 35%, while EF increased by 27% (p < 0.001). Conclusions There were hemodynamic improvement in the lower leg after varicose vein surgery including HLS, RFA, and EVLA.
