FEATURES OF THE PERSON HEART TOPOGRAPHY IN 1622 WEEKS OF PRENATAL ONTOGENESIS

Abstract

Full Text

Background. Now the person heart is one of subjects to fetal operations. Aim. Therefore information about heart topography and it features in the prenatal period are necessary for doctors of various profile. Obtaining new data on heart topography at person fetus of 16-22 weeks of development became a research objective. Material and Methods. Material of this research is 30 fetus torsos of both sexes without pathology of chest and abdomen organs. Results and Discussion. Results of a research have shown that in 16-22 weeks of prenatal ontogenesis the superior, inferior and right borders of heart are extended with the stability of left border. The left border of heart throughout all studied age period doesn’t change the localization and has the projection on the left anterior axillary line. The right border of the heart is displaced to the right by 22nd week: at 60% of samples have the projection on parasternal line, at 40% - on right middle clavicle line. Heart is displaced closer to the anterior chest wall by 22nd week. Sintopiya of fetal heart has individual distinctions which are shown in relationship of heart with the thymus, the esophagus and the left lung. Distances from heart to surrounding organsare increased ranging from 5% (to the left main bronchi) up to 69% (the right vagus nerve). Conclusions. Thus the heart topography in 16-22 weeks of ontogenesis has the features which have to be considered at fetal operations.
