Objective:To discuss the efficiency and influential factors that can improve the function of deep venous valve after superficial vein surgery of lower extremity.
:Methods :Sixty (70 limbs) patients with primary deep venous insufficiency were enrolled to accept surgical management of superficial vein systems. All patients were examined with color Doppler ultrasonography, and their deep venous hemodynamics index was measured, recorded and compared before operation and six months after operation.
:Results:The total improvement rate of the deep venous hemodynamics after superficial vein surgery was 65.7%. For those patients with disease course longer than 20 years, the rate of inefficiency was 4.355 times more than those whose course was less than or equal to 20 years, and for those patients with reflux both in superficial femoral vein and popliteal vein, the rate of inefficient improvement was 4.247 times more than those with reflux only in a single vein. For those patients who were older than 60 years, the rate of inefficient improvement was 3.516 times more than those younger than 60 years.
:Conclusions:This study demonstrates that the superficial vein operation for varicose veins of lower extremity can improve deep vein valve function to some extent. It has a good shortterm effect, and can be used selectively in the patients with early deep venous insufficiency.
