PURPOSE: Endovenous radiofrequency abalation (RFA) has been a viable treatment option for patients with saphenous varicose veins. The purpose of our study is to assess venous hemodynamic change before and after RFA by using air plethysmography (APG).
PATIENTS AND METHODS: We prospectively analyzed the data of consecutive 91 patients with 124 limbs who underwent RFA for primary varicose veins. Overall venous hemodynamics of the limb was assessed using APG. The venous filling index (VFI) was determined as a measure of reflux (normal range, <2mL). Duplex scanning were performed to evaluate saphenous vein occlusion, deep venous thrombus and endovenous heat-induced thrombosis (EHIT).
RESULTS: The VFI were significantly reduced from 4.1±3.1 preoperatively to 1.4±1.0, 1.3±0.8 and 1.4±1.2 at 1 week, 1 month and 4 month postoperatively, respectively. The percentage of the VFI>2 ml/s was 77% preoperatively, while it significantly decreased to 17 %, 16%, and 18% at 1 week, 1 month, and 4 month postoperatively, respectively. Duplex scanning showed 100% of saphenous vein occlusion and no significant EHIT II-IV.
CONCLUSIONS: Correction or significant improvement of venous reflux was achieved by RFA. Together with duplex scanning findings, RFA is a safe and hemodynamically effective treatment for varicose veins.
