The importance of deep venous reflux velocity as a determinant of outcome in patients with combined superficial and deep venous reflux treated with endovenous saphenous ablation

Measurement of maximal reflux velocity (MRV). In both images, cuff release occurs at the first vertical line. The x-axis is time with the large hash marks indicating 1 second. At 0.5 seconds after cuff release, the velocity of reverse flow (in cm/sec) is identified and recorded as MRV. A, High velocity reflux in the popliteal vein of 38 cm/sec. B, Low velocity reflux in the popliteal vein of 8 cm/sec.

Correlation between pre-ablation Maximal Reflux Velocity (MRV) and post-ablation venous filling index (VFI) in limbs with GSV reflux and femoral and/or popliteal reflux (limbs with SSV reflux removed).

Venous filling index (VFI) and Venous Clinical Severity Score (VCSS) before and after endovenous ablation (EVA) in patients with saphenous reflux and deep venous reflux in the common femoral vein (P < .001 for both VFI and VCSS).
