Способ определения степени венозной патологии в зависимости от индекса деформабильности эритроцитов

Abstract

Aim. To study the ability of erythrocytes to deformability in patients with chronic diseases of the veins of the lower extremities. Materials and methods. From March to July 2019, we conducted a study of the deformability of erythrocytes in 271 railway workers using the method of laser diffractometry. The study of blood samples was carried out at the Department of Human and Animal Anatomy and Physiology of the Institute of Biology. At the same time, there were 182 people with varicose veins of the lower extremities, which was confirmed by the data of ultrasound angioscanning of the veins. Results. Studying the deformability of red blood cells of venous blood in patients with chronic venous disease of the lower extremities, we have identified certain patterns. With the increase in the clinical stage (form) of the disease of varicose veins of the lower extremities, the deformability of erythrocytes decreases, the deterioration of blood parameters is determined, which is confirmed by the data of a small coagulogram and a general blood test. The deformability index in the range from 0.12 to 0.42 indicates a violation of venous outflow in the subcutaneous venous system of the lower extremities, the deformability index from 0.42 and above indicates the presence of a thrombotic process in the deep veins of the lower extremities. Conclusion. With an increase in the erythrocyte deformability index, venous insufficiency increases, and venous outflow worsens. The higher the severity of the disease (clinical form C4-6), the lower the deformability of erythrocytes. In patients with VBLK, as the disease progresses, there is a decrease in the deformability of erythrocytes (i. e., in patients with the clinical form according to CEAP C2-3, the deformability is higher than in C3-4; in patients with C3-4, it is higher than in С4-5 … etc.).
