[Edemas in chronic lower extremity venous insufficiency: clinical manifestations, medical and surgical treatments].

The review presents data on the causes and pathogenesis of lower extremity (LE) edemas with special emphasis on the edemas occurring in chronic LE venous insufficiency. It discusses the possibilities of noninvasive and surgical treatments for LE edemas in venous insufficiency. Particular attention is given to the possibilities of phlebotonic therapy.

[Hypolipoproteinemia and secondary role of atherosclerosis in the development of ischemic heart disease in patients with polycythemia vera].

Relationship between presence of coronary heart disease (CHD), coronary risk factors (parameters of lipid transport system and hypertension) and disturbances of microcirculation was studied in patients with myeloproliferative blood disease Polycythemia Vera (PV). Probability of tissue (including blood vessel wall) cholesterol accumulation was estimated by measurement of its content in skin surface layers. PV patients (n=55, including 27 patients with CHD) had predominant hypolipoproteinemia with normal proportion of various lipoprotein classes.

[Erythrocyte cholesterol content in polycythemia vera: relation to ischemic heart disease].

Relative cholesterol content and its distribution between erythrocytes and plasma were studied in 34 patients with polycythemia vera (PV) both with and without concomitant coronary heart disease (CHD). Deformability of erythrocytes, disturbances of microcirculation (blood flow fragmentation, decrease of capillary density) were also assessed. Erythrocytes cholesterol/phospholipids molar ratios (0.
