[Possibilities of predicting the outcome of diseases after cardiosurgical interventions].

A multifactorial correlation and regression analysis with the use of a pack of applied programs "SAND" in the computer SM-4 was performed for prognosis of the outcome of the disease in 38 patients with acquired heart diseases operated upon under conditions of extracorporeal circulation. A linear mathematical model was obtained which allowed predicting the course of the postoperative period and outcome of the disease of cardio-surgical patients with 70-80% probability.

[The surgery of suppurative-septic diseases of the heart: its characteristics and outlook].

An analysis of the experience with surgical treatment of more than 320 patients with infectious endocarditis has shown the necessity to isolate pyo-septic cardiosurgery into an independent line. The arguments are: the specificity of the contingent of patients, special features of diagnosing, operative technique and period of rehabilitation, sanitizing regimen of the artificial blood circulation and others. The organizational aspect includes the necessity of active surgical tactics in treatment of pyo-surgical foci of cardiac localization. Successful treatment of this category of patients can be performed due to the availability of special antiseptic centers which must closely cooperate with cardiosurgical departments functioning in the regimen of emergency diagnostics and cardiac surgery.

[Plasmapheresis and the immune system in heart surgery patients].

An analysis of results of investigation of the influence of apparatus plasmathrombocytopheresis on the immune status of 29 patients with heart diseases is presented. It was shown that intensive plasmapheresis was not followed by substantially decreased level of IgA, IgM and C3 fraction of the complement. The curative effect of this operation in cardiosurgical patients manifests itself as decrease of the level of circulating immune complexes.

[Surgical treatment of septic endocarditis in drug addicts].

The clinical picture of endocarditis in addicts is characterized by mainly right-sided localization of the process in the heart, poor auscultatory picture of the heart, pleuro-pulmonary manifestations against the background of a feverish course of the disease. The leading role in diagnosis of infectious endocarditis in addicts should be given to echocardiography. A description of three cases of surgical treatment of infectious endocarditis in addicts is presented.

[Use of cryopreserved autologous thrombocytes in cardiac surgery].

Cryopreserved autologous thrombocytes were used for the prevention of thrombohemorrhagic complications after operations with extracorporeal circulation in 17 patients. An obvious hemostatic effect was produced. Studies carried out in cardiosurgical patients showed satisfactory maintenance of the main hemostatic characteristics of the blood platelets during cryopreservation. Plasma thrombocytapheresis in an apparatus allows simultaneous preparation of the autothromboconcentrate and large amounts of autoplasma used for filling the extracorporeal circulation apparatus, and compensation for the blood loss.

[Pathogenesis of thrombus formation in varicose veins].

Under observation there were 60 patients operated upon for varicose dilatation of the lower extremity veins. It was established that the reconstruction of the walls of the altered vessels had a substantial influence on processes of the parietal microthromboformation and facilitated local alteration of hemodynamics and elevation of the aggregation properties of thrombocytes.

[Comparative characteristics of reactions of central hemodynamics to the exfusion of blood and plasma in surgical diseases].

Complex clinico-laboratory and functional examinations of 102 patients have been made who had heart diseases, lung carcinoma, benign tumours of the lungs and mediastinal organs. Autoblood of 34 patients was prepared in the preoperative period (450-600 ml). A single taking the plasma by the method of double plamapheresis (500 ml) was performed in 48 patients. Autoplasma was prepared in 20 patients by the apparatus PF-0.5 (1200 ml). It is concluded that patients without pronounced insufficiency of blood circulation and anemization can easily endure exfusions of considerable volumes of blood and plasma.

[Autoplasma as a basis of the transfusion program in surgical interventions with artificial circulation].

A clinico-laboratory examination of 17 cardiosurgical patients was performed. All the patients had been subjected to operations under conditions of artificial circulation with the native autoplasm perfusate. Positive effect of plasmapheresis was noted in patients with a pronounced disturbance of blood circulation. The applied method of transfusiological maintenance of cardiosurgical operations makes them cheaper and reduces risk of the appearance of infectious diseases and causes less pronounced changes of parameters of humoral immunity.
