Evaluation of the efficacy of heparins of varying molecular mass and duration of their use in the treatment of patients with acute venous thrombosis.

This paper analyses the results of examination and treatment of 90 patients with acute thrombosis in the inferior vena cava system. To verify the diagnosis, use was made of contrast phlebography (retrograde iliocavography), ultrasound angioscanning, and perfusion scanning of the lungs, The treatment was carried out using heparins of varying molecular mass given for a short and longer time together with indirect anticoagulants. It has been demonstrated that the use of low-molecular heparin does not produce any noticeable changes in the hemostatic system, which can be revealed by standard coagulation tests.
