[Chronic venous insufficiency. Pathogenesis and modern diagnostic possibilities].
Ultrasound angioscanning is one of modern highly effective diagnostic techniques in trophic lesion stage of varicose disease. This technique allows for reliable determination of the levels and character of pathological venous refluxes, having significant impact on the course of the disease and leading to chronic venous insufficiency (CVI). The authors revealed the leading role of profound venous valvular insufficiency in the progress of CVI, stressing the necessity for its correction. They point out to the causes of low horizontal venous-venous refluxes and valvular insufficiency of gastrocnemius muscle-venous sinuses leading to isolated insufficiency in the distal segments of posterior tibial veins, which intensifies CVI progress at the account of disturbances in the functioning of tibial muscular-venous pump.
