Abstract. A comparative prospective study was conducted to study the relationship between metastatic progression of a malignant tumor and venous thromboembolism. Patients with malignant neoplasms with distant and regional metastases (main group) and patients with local forms of malignant tumor (control group) were subjected to ultrasound examinations of the veins of the inferior vena cava and echocardiography. The number of venous thromboembolic complications among patients with regional and distant metastases was significantly higher (39-41%) than among patients with local forms of malignant neoplasms (10%). Venous thromboembolism are a reflection of the metastatic potential of a malignant tumor.
