The clinical significance of below-knee great saphenous vein reflux following endovenous laser ablation of above-knee great saphenous vein.
Phlebology. 2009 Feb; 24(1):17-20.P

Abstract

AIMS

The standard technique for endovenous laser ablation (EVLA) for varicose veins due to great saphenous vein (GSV) reflux involves obliteration of the above-knee (AK) GSV. This study assesses the significance of persistent below-knee (BK) GSV reflux following such therapy.

METHODS

Sixty-nine limbs (64 patients) with varicosities and GSV reflux underwent AK-EVLA. Post treatment, GSV reflux (ultrasound: six, 12 weeks) and Aberdeen varicose vein severity scores (AVVSS, 12 weeks) were assessed, and residual varicosities treated with foam sclerotherapy (six weeks).

RESULTS

The untreated BK-GSV remained patent in all limbs. Ultrasound showed normal antegrade flow in 34/69 (49%, Group A), flash reflux<1 s in 7/69 (10%, Group B) and >1 s reflux in 28/69 (41%, Group C). Although AVVSS improved in all groups (P<0.001): A: 14.6 (8.4-19.3) versus 2.8 (0.5-4.4), B: 13.9 (7.5-20.1) versus 3.7 (2.1-6.8), C: 15.1 (8.9-22.5) versus 8.1 (5.3-12.6) the improvement was less in Group C (P<0.001 versus A and B) and was associated with a greater requirement (A: 4/34 [12%]; B: 1/7 [14%]; C: 25/28 [89%]) for sclerotherapy (persisting varicosities) (P<0.001).

CONCLUSION

Although AK-GSV EVLA improves symptoms regardless of persisting BK reflux, the latter appears responsible for residual symptoms and a greater need for sclerotherapy for residual varicosities.
