PATTERNS OF MORPHOLOGICAL CHANGES OF PLACENTAL TISSUE AT ASCENDING, HEMATOGENIC AND MIXED WAYS OF INFECTION

Abstract

The purpose of study work is to determine the leading ways of infection, the microbial spectrum of pathogens and morphological markers of placental structures in ascending, hematogenous and mixed contamination. During the morphological examination of placenta, 4 groups were marked out: without signs of infection of the placenta (n= 53), with ascending (n = 82), hematogenous (n = 40) and mixed infection (n = 49). It was revealed that structural changes in the placenta in all groups with intrauterine infection are involutional-dystrophic in nature. At the same time, compensatory reactions prevailed in the group without infection. The development of the inflammatory process in the placenta in ascending and mixed ways of infection was of a phasic nature, and reached in every third patient the maximum degree of infection - the infection of the umbilical cord.
