Description

<p>The aim of this study was to investigate the rate and cause of recurrence after endovenous laser ablation (EVLA) of the great and small saphenous vein (GSV & SSV) from 3-year follow-up results using duplex ultrasound in Japanese patients with varicose veins. We reviewed 149 limbs (follow-up rate 83%) in 141 patients undergoing EVLA with 980 nm diode laser. After EVLA of the GSV (127 limbs), accessory saphenous vein (ASV) insufficiency was detected in 3 (2%) at 1 year, 5 (4%) at 2 years and 7 (6%) at 3 years, thigh perforator vein reflux in 3 (2%) at 1 year, 5 (4%) at 2 years, 7 (6%) at 3 years, recanalization with reflux in 0 (0%) at 1 year, 2 (2%) at 2 years, 3 (2%) at 3 years and neovascularization with reflux in 0 (0%) at 1 year, 1 (1%) at 2 years and 1 (1%) at 3 years. After EVLA of the SSV (29 limbs), saphenopopliteal junction (SPJ) incompetence was found in 1 (3%) at 1 year, 6 (21%) at 2 years and 8 (28%) at 3 years. Reoperation was performed in 2 limbs for ASV insufficiency and thigh perforator vein reflux respectively. In conclusion, ASV insufficiency, thigh perforator vein reflux, GSV recanalization and SPJ incompetence can be significant causes of recurrence after EVLA for varicose veins.</p>
