[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.

[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.

[Morphometric characteristic of abdominal and retroperitoneal organs according to data of supravital computer tomography].

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.
