Saphenous Vein and Perforating Vein Surgery in Primary Varicose Veins

Abstract

We report our prospective study of preservation of perforating veins (PV) and great saphenous vein (GSV) with review of the literature. Some incompetent PV become competent after saphenous surgery, therefore, not all of the incompetent PV needs operative ligation. Moreover, some PV becomes incompetent after surgery, which may be due to complex hemodynamics of superficial venous flow in addition to deep venous reflux. In many cases, GSV incompetence of the lower leg disappear after GSV stripping from the groin to just below the knee, if the GSV does not appear tortuous dilatation. We conclude that stripping of incompetent GSV below the knee portion could not be necessary, if the GSV does not present tortuous dilatation, in the view point of reducing saphenous nerve injury.
