Abstract

The purpose of the study To justify different types of surgical approaches at damages "hard" segments of the liver, taking into account topographic and constitutional human features by using X-ray method computer model. Materials and methods For the study developed a software product for determining the optimum surgical access to "difficult areas" segments of liver, that consists of four modules: _, processing of computer tomograms (CT), classification of 3D models and analyze information. For objectification research results, was decided to use quantitative criteria to be met by surgical approach proposed by A.Iu. Sozonov-Iaroshevich (1954). Results and their discussion The reconstruction of 243 simultaneously performed CT examinations thoracic and abdominal cavities with intravenous contrast were obtained model chest and abdomen _ with vascular system. Then, simulation of damage done "hard» (VII-VIII) and hepatic vein segments by marking them. Conclusion The data, which suggest that the majority (67.5%) patients optimal access to "difficult areas" segments of the liver is torakofreno laparotomy through IX intercostal space
