The aim of the study was to study the morphological structure of the liver in newborns with congenital cytomegalovirus infection. The material for the study was the liver of 36 full-term newborns who died on the 2nd-5th day of life from birth trauma, intranatal and postnatal hypoxia. The main study group included 16 full-term newborns with congenital cytomegalovirus infection. The comparison group included 20 newborns from mothers without any viral infections, as well as moderate, severe somatic diseases and obstetric pathology during pregnancy, and these babies died at the 2nd-5th day of life from birth trauma, intrapartum and postnatal hypoxia. The main cause of death of children of early neonatal age was intrauterine infection which was clinically manifested by moderate or severe cerebral ischemia with hypertension-hydrocephalic syndrome, pseudocysts of the vascular plexus, subependymal and subarachnoid hemorrhages, monocytosis, vesiculosis, pneumonia, hepatitis and meningoencephalitis and antenatal hypoxia caused by the development of subcompensated placental insufficiency. When describing the liver, the attention was drawn to the following macroscopic and pathohistological changes in the organ: 1) the condition of the capsule of the organ; 2) the change of the general plan of a structure; 3) the reaction of the bloodstream of the liver: 4) the condition of the portal tracts; 5) the state of the lumen of the bile ducts and its epithelium. The material was fixed in 10% neutral formalin, dehydrated in alcohols and poured into paraffin. For observational microscopy, histological sections 5-7 μm thick were stained with Böhmer hematoxylin and eosin. Morphological examination of the liver in the newborns of the main group showed an increase in the frequency of detection of subcapsular hematomas, pronounced congestion of sinusoids, foci of lymphohistiocytic infiltration of the connective tissue of the portal tracts, small-focal proliferation of Kupffer cells, alterative and proliferative changes in the epithelium of the bile ducts, as well as cells with viral metamorphosis. The revealed structural changes in the morphological structure of the liver in full-term newborns indicate the development of pronounced dyscirculatory, alterative and inflammatory changes in the liver of cytomegalovirus genesis.
