[The hemodynamic significance of normal vertical blood reflux based on dopplerographic data and in patients with primary varicose veins of the lower extremities].

Data of echophlebodopplerography on "ULTRA-PVD" (USA) were used for studying the frequency and hemodynamic significance of vertical reflux of blood in the deep veins of lower extremities in varicose patients. A group of 50 healthy men and women and 80 patients with different stage of varicose disease were studied. A comparison of the data obtained allowed determining a reliable static criterion of the retrograde wave duration when performing a test with proximal compression. It was shown that under normal conditions it should not exceed 1.5 sec. Three degrees of the retrograde blood flow were distinguished. Indications for surgical correction of the relative valve deficiency of the deep lower extremity veins must be established in each concrete case. Since 1993 200 patients with primary varicose veins have been examined and operated upon. Good and excellent results (96%) testify to the effectiveness of the correction of deep vein hemodynamics which can improve surgical treatment of this pathological condition.
