 Abstract. The present study analyzed the results of monitoring 109 cancer patients during the first year after special treatment. Patients were divided into two groups: the main group and the comparison group. Patients of the main group (79 patients), to identify embologogenic venous thrombosis (sources of pulmonary thromboembolism), performed ultrasound examinations of the veins of the inferior vena cava and echocardiography with a periodicity of one month. Patients of the comparison group (30 patients) had the same studies only in the presence of clinical manifestations of venous thromboembolic complications. In 16 patients of the main group, embologogenic venous thromboses were detected in a timely manner. Measures of targeted prevention of pulmonary embolism, selected in view of the results of ultrasound studies, prevented the development of pulmonary embolism and the occurrence of sudden death among patients of the main group. In the comparison group, there were two cases of sudden death and three patients in the comparison group were diagnosed with pulmonary embolism.

Key words: pulmonary embolism, cause of death of cancer patients, venous thrombosis, ultrasound.
