    Is there a relationshi between deep venous reflux and superficial vein reflux ?

    Researchers at the Department of Surgery, Eniwa Midorino Clinic, Eniwa, Japan and 3 other institutions have published a manuscript looking at the effect of superficial venous reflux ablation on deep vein anatomy and physiology.  The article was published in Vascular and Endovascular Surgery (see reference below). 

    The aim of the study was to investigate the influence of superficial venous ablation on deep venous dilation and reflux in patients with saphenous varicose veins, and to elucidate the association between superficial venous reflux and deep venous morphology and hemodynamics.

    The data of 154 patients with 223 limbs, who underwent endovenous radiofrequency ablation (RFA) of the great saphenous vein for primary varicose veins.

    Hemodynamic and morphologic changes were evaluated before and 1 month after radiofrequency ablation. 

    The authors showed that superficial venous ablation significantly reduced deep venous dilation and reflux in patients with saphenous varicose veins.

    They also showed that significant correlations existed between the varicose veins or venous filling index (VF0), which reflected superficial venous reflux, and the diameter of the deep veins.

    The authors concluded that volume overload due to superficial venous reflux is associated with deep venous morphology and hemodynamics.

    Comment:  The current study shows that treating suerficial venous reflux has benefits in reducing deep venous insufficiency.
