The objective of the present study was to elucidate the main causes underlying the development of venous thromboembolism in pregnant women. The secondary objective was to evaluate the possibility to introduce counseling by a phlebologist into routine management of pregnancy. It was shown that the excess body weight in pregnant women contributes to the development of thrombosis and that such women need special attention on the part of attending physicians. The described therapeutic modalities including the use of individually adjusted compression hosiery and intake of a diosmin-containing phlebotropic drug provide the safe and efficacious tools for the elimination of clinical manifestations of venous thrombosis. At the same time, the use of proposed preventive measures, such as dynamic observation by a phlebologist, the choice of adequate compression hosiery, and therapy with phlebotropic agents, contributes to the reduction of the incidence of venous thromboembolism in pregnant women.
