Aim. To estimate the effectiveness of standard preparations of the extracts of grape red leaves introduced into combined therapy of the patients presenting with venous thromboembolic complications at the stage of outpatient treatment. Material and methods. The results of the treatment of 3 groups of the patients who had suffered pulmonary thromboembolism were available for the analysis. Combined outpatient treatment of the patients of group 1 was supplemented by the intake of diosmin-containing phlebotropic pharmaceuticals. The patients of group 2 were given standard preparations of the extracts of grape red leaves, those of group 3 did not use angioprotectors. The results of the three therapeutic modalities were compared upon discharge from the hospital and after a 3-month follow-up period. The outcome of the treatment was estimated based on dynamics of personal complaints ( based on the visual-analog scale), the quality of patients' life (based on the SF-36 questionnaire), clinical status (general examination, measurements of malleolar circumference), and parameters of venous hemodynamics (data of ultrasound studies). Results. The patients of groups 1 and 2 showed similar positive dynamics of subjective and objective characteristics that prevailed over irregular dynamics of the same characteristics in the patients of group 3. The patients of the first two groups reported alleviation of pain and oedematous syndromes that was confirmed by decreased malleolar circumference (by 19,7±0,2 mm and 19,7±0,2 mm respectively compared with 10,4±1,6 mm ion group 3). The diameter of common femoral vein decreased whereas the averaged linear velocity in the spectrum increased (p<0.03). The slowest recovery rate of venous hemodynamics and major health status characteristics was documented among the patients of group 3. Conclusion. The present study has demonstrated that the combined outpatient treatment of the patients presenting with venous thromboembolic complications with the use of standard preparations of the extracts of grape red leaves is comparable with therapy using diosmin-containing phlebotropic pharmaceuticals in terms of effectiveness and safety. The beneficial effect of both therapeutic modalities is superior to that of isolated anticoagulation treatment.
