Introduction. Improvement of ultrasonic methods of research has opened up new possibilities for studying two-way communication between the procoagulant activity of malignant tumors and the growth of the metastatic potential of tumor cells. The aim of this study is to identify the relationship of ultrasonographic signs of idiopathic venous thrombosis and malignancies.

Methods. Surveyed and observed 215 patients with malignant tumors. Patients were divided into two homogeneous groups: main group ― 105 patients; a control group of 110 patients. A sign of the difference between the groups was the presence of idiopathic venous thromboembolism in patients of the main group.

Results. Within two years after the special treatment, distant metastases of malignant tumors were found in 33% of patients the main group and in 8% of patients in the control group. Diagnosis of distant metastases of malignant tumors coincided with echographic signs of blood clots in the previously intact segment of the vein and the progression of venous thrombosis: in the main group ― 60% of patients; in the control group ― 56% of patients.

Conclusion. Dynamic changes of ultrasonographic signs of idiopathic venous thrombosis are closely linked with the progression of cancer and can be used as a prognostic marker of metastasis of malignant tumors.

Key words: idiopathic venous thrombosis, procoagulant activity malignancies, metastasis of malignant tumors.
