Infecting of decidua in premature labor

In this work we have studied the changes of decidua in premature labor and analysed the pregnancy, labor, postnatal period and neonatal period in women with infection of decidua. We have obtained existing of certain pathological changes of decidua in 98% of all cases of premature parturition. In this part there were 68% of cases with infectious disorders. And almost always (in 93%) they were accompanied by involutionary-dystrophic and dyscirculatory changes of decidua and disorders of ripening of villi. We have revealed an inflammation with the major forms of localization as damage of decidual membrane, choriodeciduitis, and intervillusitis without major localization under chorial lamina. We have also revealed damage of syncytium and stroma of villi with deposition of maternal leukocytes without involving of villous vessels in inflammatory process. This all is to confirm that the main sources infecting decidua are the foci of infection in pregnant women. Therefore, infectious agents from those foci spread into decidua by haematogenic ways.
