Objective. The aim of the study was to optimize the methods of selecting patients for inclusion in the «waiting list» for heart transplantation on the basis of available international data and the introduction of selection criteria.Materials and methods. The results of the study are based on survey data and dynamic monitoring of 49 patients (median age 38 (16; 65) years; 44 men, 5 women) who were treated from 2008-2018 in the centers: Republican Scientific and Practical Center «Cardiology», Minsk, Republic of Belarus; in the Center of cardiac surgery on the basis of Hospital «Feofania». Patients were examined during the initial examination, after 3 months, 6 months and after 1 year. Results and discussion. The first group consisted of 24 patients with CHF who were on the waiting list for orthotopic heart transplantation, for circulatory support, median age 40.95 (18.0; 65.0) years, men - 23, women - 1; The second group consisted of 25 patients with CHF who were on the waiting list fororthotopic heart transplantation without circulatory support, median age 38.56 (17.0; 64.0) years, men - 21, women - 4.Conclusions. Scientific novelty of the obtained results. For the first time in Ukraine, a road map has been developed and implemented and the dynamics of the movement of recipients who are in the «waiting list» for heart transplantation has been analyzed. Identified risk factors that affect the long-term outcomes and quality of life of patients with heart failure III-IV functional class according to the NYHA classification. Criteria for selection of patients for primary heart transplantation have been developed and implemented. For the first time in Ukraine, a «waiting list» for a heart transplant has been formed.

Changes in liver blood flow and functional status of liver transplants with different types of venous outflow reconstruction have not been fully studied. A graft with optimal blood flow characteristics in a living family donation is one of the key factors that determines its functional state. The Aim. Comparison of regional hemodynamics of the liver and biochemical parametersof blood after transplantation of the right lobe from a living related donor with and without amedian vein.Materials and methods. Based on our algorithm, which included analysis of the variational anatomy of the hepatic veins of the donor to determine the type of dominant vein, transplants were selected for 76 recipients: 39 patients (group 1) were transplanted right lobe of the middle vein and 37 patients (group 2) – right lobe without meddle vein. For comparative analysis, we used data from blood biochemical parameters and data from regional hemodynamics of grafts: volumetric portal blood flow, linear velocity and resistance index in the hepatic artery in both groups during the first week and on the 10th, 14th, 21st, 30th day after transplantation.Results. Using the described graft selection algorithm, we obtained the following results on the 30th day after transplantation: in group 1 there were higher values of volumetric portal blood flow compared to group 2 at all stages of observation (1110 ± 62 ml/min and 922 ± 41 ml/min, p = 0,013864 in groups 1 and 2, respectively); the resistance index in the hepatic artery was statistically significantly higher in group 2 – 0.61 ± 0.01 compared with group 1 (0.63 ± 0.01, p = 0.042722); serum bilirubin level in group 1 was statistically significantly lower compared to group 2 (33.4 ± 9 and 39.8 ± 3.4 μmol/l, respectively, p = 0.0377); serum transaminases, alanine aminotransferase and aspartate aminotransferase, were statistically significantly lower in group 1 compared with group 2 – alanine aminotransferase – 50 ± 3.3 and 78.6 ± 8.2 U/l, respectively (p = 0.0022), aspartate aminotransferase – 42 ± 2.9 and 62.4 ± 8.9 U/l, respectively (p = 0.0282)).Conclusions. With the dominant type of middle hepatic vein in transplants of the right lobe, it is necessary to perform the right lobe of the liver with the middle vein. If the right vein is dominant – the right lobe of the liver without the inclusion of the middle vein. Adequate venous outflow, with a sufficient volume of the graft of the right lobe of the liver, determines the functional mass of the graft.

This article presents an analysis of the stages of psychological training of future transplant coordinators within the framework of the implementation of the first ZMAPO Transplant Coordinator Program. The introduction of the newly developed program for the training of future transplant coordinators has reflected some of the complexities of the psychological and pedagogical process: first, a lack of purely psychological knowledge and skills, certain problems of mastering new theoretical material, certain difficulties in overcoming barriers to communication. But all this was offset by a desire to get new interesting information, a desire to learn something new, and to develop skills for direct dialogue with potential donors and their relatives.

Objective. The aim of the study is to establish the effectiveness of mechanical support of blood circulation of patients with end-stage heart failure depending on the method of surgical correction. Materials and methods. The results of the study are based on the data of examination and dynamic observation of 73 patients (median age 44 (16-69) years, 68 men, 5 women) who were treated from 2008-2019 іn the following medical institutions: Republican Scientific and Practical Center «Cardiology» (Minsk, Republic of Belarus) and Center of cardiac surgery on the basis of Hospital «Feofania». Patients were examined during the initial examination, after 3 months and after 1 year. Results and discussion. As a result of the study found, indications for surgical treatment of patients with end-stage heart failure those are the following criteria: left ventricular ejection fraction (LV EF) <20%, (p < .0001).

Aims. Improve the technique of bone plastics of the mandible with a free autogenous rib graft.Materials and methods. A retrospective analysis of 41 case histories of patients undergoing surgical treatment in connection with the replacement of the mandibular defectsacquired due to tumors, injuries, osteomyelitis at the clinic of maxillofacial surgery in 2003-2018 was carried out. The technique of osteoplasty of the mandible with free autogenous rib graft has been improved by expanding the technical possibility of reliable fixation of bone fragments with titanium plates and screws, as well as tight installation of autograft in the bone defect and creating favorable conditions for the primary osseointegration. The own method of harvesting and formation of autogenous rib graft is proposed. For 15 years, not a single complication was identified and there was no rejection of the free autogenous rib grafts.Conclusions. This technique is simple, safe, and can be effectively used to reconstruct long-span mandibular defects with minimal complications in selected patients.
