[Morphology of the compensatory-adaptive responses in the placenta of multiparous women in uncomplicated pregnancy].

125 placentas of women with many (5-17) deliveries and 100 control placentas (with 1-2 deliveries) were studied morphologically. It is shown that placentas of women with 1-2 deliveries retain their structure, compensatory reactions are most active in the central part of the placenta. After 5-9 deliveries hemodynamic disturbances are observed, disorganization processes are less pronounced, the level of compensatory-adaptive processes increases. Hemodynamic disturbances and structural disorganization are observed after 10-17 deliveries with pronounced compensatory processes in the peripheral parts of the placenta. Dissociated disturbance of the villi maturation are revealed after numerous deliveries.
