Perfusion Lung Scintigraphy in Patients With a Pulmonary Hypertension of a Various Etiology

Abstract

The pulmonary hypertension is characterized by increase of pulmonary vascular resistance, pressure in a pulmonary artery, remodeling of heart and vessels and the lowest survival of patients. It agrees offered in 2009 the European society of cardiologists to algorithm a ventilation/perfusion scintigraphy takes the central place in differential diagnostics between various forms of a pulmonary hypertension. The scintigraphic picture is well studied at patients with the pulmonary hypertension which has developed owing to the transferred thromboembolism of branches of a pulmonary artery. The distributions of RFP given direct comparison and nature of changes of perfusion depending on a genesis of pulmonary hypertension and gravity of a disease in literature aren't presented. At the same time the knowledge of features of scintigrams can be useful in differential diagnostics and a forecast assessment at patients with a pulmonary hypertension of a various etiology.
