Valvular incompetence in superficial, deep and perforator veins of limbs with varicose veins

Abstract

Venous valvular incompetence was investigated with Doppler technique in 296 limbs with untreated primary varicose veins. Partial or complete insufficiency of the long saphenous vein was found in 95%. Six patterns of incompetence of this vein could be distinguished. Insufficiency of the short saphenous vein was present in 15% of the limbs and perforator incompetence in 45%. Femoral and/or popliteal vein reflux was found in 20% of the limbs. In eight limbs (2.7%) with verified primary deep venous insufficiency there was a moderate or severe degree of femoral and popliteal venous reflux. Skin changes secondary to the venous disease were present in 18% of the limbs, mainly those with incompetence of perforator and long saphenous veins. Doppler investigation of varicose limbs give valuable information and can be recommended as a standard pre-treatment test.
