[Assessment of the pulmonary blood flow changes in thromboembolism of small branches of the pulmonary artery].

Patients with thromboembolism of small branches of the pulmonary artery (TESPA) were examined by rheopulmonography (RPG) for the pulmonary blood flow over the zones of thromboembolism and uninvolved parts of the lungs. The study was performed at the initial disease stage, on days 3-7 of the disease and before the patient's discharge from hospital. It was shown that pulmonary circulation undergoes some successive changes.
