The aim of the study was to study the possibilities of ultrasonic dopplerography in the diagnosis of chronic venous insufficiency (CVI) of the lower limbs.
Materials and methods.A total of 176 patients with CVI were examined. The method of color dopplerography was used.
Results and discussion. CVI in the examined patients manifested a variety of clinical symptoms. To assess the tone of the venous wall, the elasticity index (IE) of the total femoral and popliteal veins was determined, to determine the "normality" of the anatomical structure of the large saphenous vein on the thigh, the hypoplasia index was determined. Having characterized the hemodynamic significance, all the examined patients were divided into three groups according to the degrees of severity. In the first group, when samples were performed on the valves in the saphenofemoral anastomosis, retrograde blood flow was not recorded, which confirmed the absence of valvular insufficiency. The value of IE did not exceed 1.37 ± 0.09. The second group recorded a retrograde blood flow lasting no more than 2 seconds, indicating a hemodynamically insignificant insufficiency. The IE value was higher than 1.37. Patients of the third group had a retrograde blood flow during the sampling of valves in the saphenofemoral anastomosis, which made it possible to reveal a hemodynamically significant valvular insufficiency, in which surgical correction was shown. The mean indices of deep vein IE exceeded the normal value and amounted to 1.7 ± 0.042 for the general femoral vein, 1.6 ± 0.02 for the popliteal vein.
Conclusions. Ultrasonic dopplerography made it possible to reveal the valve insufficiency of various sections of the venous bed of the lower extremities and to draw a conclusion about the degree of disturbance of venous outflow of the veins of the lower extremities. The study of the tonic-elastic properties of the venous wall with the help of ultrasound dopplerography is one of the important moments in the diagnosis of the state of the venous system of the lower extremities and is of great practical importance. Development of CVI is a long process, that is, under condition of detection and treatment of the disease in the early stages, it is possible to actually reduce the number of cases or prolong the development of severe forms of the disease in time.
