[Topography of the heart and major mediastinal vessels in the early fetal period of human ontogenesis].

In 176 human fetuses at prenatal weeks 16-23, the quantitative study was performed to evaluate the changes of topography of the hearts chambers, septum and valves, aorta, pulmonary trunk and superior vena cava. Te method of N. I. Pirogov, macro-microscopical dissection and preparation of the histotopographical sections in three mutually perpendicular planes were used. As a result of this study, the data on holotopy, skeletotopy and sintopy of the heart and major mediastinal vessels in the early fetal period of human ontogenesis, were obtained. Tese data may be used as reference parameters during the diagnostic ultrasonographic and magnetic resonance tomographic studies of fetuses and during surgical operations performed on fetuses.

[Topographic anatomy of human thoracic organs in the early fetal period].

The purpose of the present investigation was to evaluate the holotopy, skeletotopy and sintopy of human heart, trachea and esophagus in the early fetal period. The quantitative evaluation of the topography of these organs was given as a result of study of 100 human fetuses aged 16-24 week with the modification of N.I. Pirogov method and using the multiplane histotopographical sections in the multidimensional coordinate system. The horizontal sections were selected, that could be proposed as the standard ones. he results of this investigation may be recommended for the improvement of the ultrasonographic and magnetic resonance tomographic diagnosis and fetal surgery development.

[Morphometric characteristic of abdominal and retroperitoneal organs according to data of supravital computer tomography]. / Morfometricheskaia kharakteristika organov briushnoi polosti i zabriushinnogo prostranstva po dannym prizhiznennoi komp'iuternoi tomografii.

The method of computer tomography was used to study the individual and age-related differences were found in the topography of pancreas, kidneys, abdominal aorta and in the shape of adrenal glands. Morphometric studies performed resulted in the description of the range of these differences and in the establishment of average quantitative parameters. It is concluded that the results of computer tomographic analysis may be used for the studies of intravital topography of the abdominal and retroperitoneal organs of individual patients and for description of variants of localization of different anatomical structures.
