摘要：
FIELD: medicine.SUBSTANCE: to carry out the differential diagnostics of acute pulmonary thromboembolism and postembolic pulmonary hypertension additionally to ventilation-perfusion pulmonoscintigraphy performed is balanced radionuclide ventriculography in a tomographic mode with the following determination of the index of the ratio of transverse sizes of the radionuclide blood pool of the right heart ventricle to the left one (RV/LV), as well as by the analysis of phase polar maps and phase histograms. In case of the total V/P-inconsistency, clearness of contours of detected perfusion defects of radiofarmpreparation (RFP) accumulation, absence of the reduction of contractility and desynchronism in the area of the interventricular septum and the index of RV/LV lower than 1.0 acute thromboemolism of the pulmonary artery with favourable prediction is diagnosed. in case of incomplete V/P-inconsistency, incorrect shape, unclear contours of perfusion defects of RFP accumulation, redistribution of the perfusion radiofarmpreparation in upper parts of lungs, the presence of reduction of contractility and desynchronism in the area of the interventricular septum, as well as an increase of RV/LV index higher than 1.0, chronic postembolic pulmonary hypertension with unfavourable prediction is diagnosed.EFFECT: increased accuracy of the method for the diagnostics of acute thromboembolism of the pulmonary artery and chronic postembolic pulmonary hypertension.7 dwgИзобретение относится к медицине и может быть использовано в медицинских учреждениях, оснащенных радиодиагностическими лабораториями. Цель изобретения - повышение точности способа диагностики отстрой тромбоэмболии легочной артерии и хронической постэмболической легочной гипертензии. Для дифференциальной диагностики острой тромбоэмболии легочной артерии и хронической постэмболической легочной гипертензии дополнительно к вентиляционно-перфузионной пульмоносцинтиграфии проводят равновесную радионуклидную вентрикулографию в т
