Pregnancy terminations with chorion detachment and intrauterine hematoma formation

70 pregnant women with the threat of miscarriage and with intrauterine hematoma in the first trimester and 20 pregnant women observed in maternity welfare clinics were examined. Clinical, laboratory and instrumental methods of research were used. Features of gestation in the both groups were studied by analyzing data of ultrasonic scanning, dopplerometry, cardiotocografy; histological study of placentae and material from uterine cavity after spontaneous miscarriage was made. Chorion detachment is often combined with the inflammatory changes of fetal ovum and endometrium elements. Prolongation of pregnancy is possible in the majority of cases but meanwhile relaps of the threat of miscarriage and disorder of fetus condition in form of adaptation reduction often arise
