Abstract

Introduction. Pulmonary embolism is the second most common cause of death in cancer patients. The tumor-associated venous thrombosis and thromboembolism are sources of emboli cause small branches of the pulmonary arteries.

Methods. There were 238 cancer patients. 131 patients with malignant tumors with regional metastases were included in the main group. 107 patients with malignant tumors without regional metastases were included in the control group. In both groups, in the diagnosis and treatment period External testing carried ultrasound veins of the inferior vena cava, echocardiography with measurement of right ventricular systolic function and detection mikrotromboembolov venous system using a method of detecting migration mikrotromboembols (patent 2585698 Russian Federation).

Results. Assessment of maximum systolic blood pressure in the pulmonary artery in view of right ventricular systolic function, detection microembolisms in the venous system are highlights diagnostics continuously recurrent thromboembolism of small branches of the pulmonary artery in patients with malignancies. Among patients with malignant tumors with regional and distant metastases (the main group) venous thromboembolic complications was significantly higher than among patients with localized forms of malignant tumors (control group).

Conclusion. Microembolization small branches of the pulmonary artery is a common cause of heart failure and incurable cancer patients. Application dopplerographic detection method microembolisms migration in the venous system, echographic assessment of systolic function of the right ventricle and pulmonary hypertension allow to diagnose thromboembolism of small branches of the pulmonary arteries in patients with malignant tumors.

Key words: thromboembolism of small branches of the pulmonary arteries, cancer, venous thrombosis, metastasis of malignant tumors.
