Abstract
- The objectives of the study were to quantitatively evaluate leg edema in patients undergoing endovenous radiofrequency ablation (RFA) for saphenous varicose veins using bioelectrical impedance analysis (BIA) and to elucidate the time course of leg edema after RFA.The data of 87 patients with 128 limbs undergoing RFA for saphenous varicose veins in Eniwa Midorino Clinic from April 2018 to November 2019 were retrospectively analyzed. Saphenous vein reflux was evaluated by duplex scan. Extracellular water/total body water ratio (ECW/TBW) of the leg was measured by BIA. Moderate to severe leg edema (ECW/TBW ≥ 0.400) was defined as significant leg edema. Venous reflux was evaluated as a venous filling index (VFI) using air plethysmography.BIA revealed that 26 legs (20.3%) had significant edema and 102 legs (79.7%) did not before RFA. The proportion of patients with significant leg edema increased significantly from preoperative to 1 week after RFA (P 0.05) and decreased 1 month after RFA (P 0.01). The ECW/TBW increased significantly from preoperative (0.393 ± 0.008) to 1 week after RFA (0.394 ± 0.008, P 0.05), whereas it decreased significantly before or 1 week to 1 month after RFA (0.391 ± 0.008, P 0.05). There was a significant, moderate correlation between the decrease of the VFI and that of ECW/TBW (r = 0.34, P 0.001).This is the first study to quantitatively elucidate the time course of leg edema after RFA. Leg edema worsens one week after RFA, but it is improved one month after RFA, compared with that preoperatively.
