[Lung perfusion scanning in the comprehensive diagnosis of pulmonary thromboembolism].

The aim of the study was to define the sensitivity, specificity, and diagnostic accuracy of lung perfusion scanning (LPS) in pulmonary thromboembolism (PTE). PTE diagnostic techniques are comparatively assessed. The data on 108 patients with suspected PTE and lung perfusion defects revealed at pulmonary scintigraphy were analyzed.

[Characteristics of hemodynamic and external respiratory function in patients with concomitant wounds of the heart and lung during early postoperative period].

The parameters of intracardiac hemodynamics and external respiratory function (ERF) were studied by echocardiography and computed spirography with pneumotachometry in 123 patients with punctured and lacerated wounds of the chest in the early postoperative period. All the patients were divided into 6 groups according to the pattern of injuries. Group 1 included 25 patients with chest wound without organ damages; Group 2 comprised 42 patients with wound of the lung; Group 3 consisted of 22 patients with wound of the left ventricle (LV); in Group 4 there were 11 persons with wound of LV and the lung; Group 5 included 8 victims with wound of the right ventricle (RV); and Group 6 comprised 15 patients with wounds of the lung and RV.

[Characteristics of cardiac insufficiency in myocardial infarction in the pre-rupture period].

Of 61 patients with myocardial infarction (MI), complicated by cardiorrhexis (CR), 72% had heart failure (HF) in the prerupture period. A small MI zone (35.8 +/- 2.

[Ultrasonic diagnosis of papillary muscle dysfunction in patients with acute myocardial infarct].

A study of 123 patients with acute myocardial infarction demonstrated the potentials of combined use of sectoral scanning and Doppler echocardiography in the diagnosis of the papillary muscle dysfunction syndrome. Two basic pathogenetic mechanisms of papillary muscle dysfunction associated with acute myocardial infarction are identified: direct involvement of the papillary muscles and papillary muscle dysfunction developing in cases of marked left-ventricular dilatation associated with acute aneurysm of the heart. Two-dimensional impulse Doppler echocardiography is found to be a more sensitive method, as compared to sectoral scanning, in the diagnosis of mitral lesions in patients with acute myocardial infarction.
