Features of retrochoir hematomas and their effect on the course of pregnancy

Keywords: retrochoir hematoma, premature birth, fetoplacental complex, fetal growth retardation, dopplerometry


The aim. Study of the features of retrochoir hematomas (RHG) and their influence on the formation of the placenta, the course of pregnancy, as well as the occurrence of premature birth.

Materials and methods. 2 groups of pregnant women were selected depending on the frequency of RHG formation: 1 group – 60 pregnant women with recurrent RHG, group 2 – 50 pregnant women with RHG, which was detected only in the early stages of pregnancy. extragenital and genital pathology did not differ reliably. All the women studied were anamnesis, examined, and ultrasound and dopplerometry were performed.

Statistical methods included an assessment of statistical significance using Student's t-criterion and criterion X2 and were considered significant at p<0.05.

Results. Supracervical localization of hematomas prevailed in the studied pregnant women, namely: in group 1 – 51.7 % (in 31 pregnant women) and 68 % (in 34 women) in group 2. The same pattern was observed regarding the involution of hematomas.

Changes in the yolk sac were found in both groups with RHG (in 6.7 % of women (i.e., in 4 pregnant women) of group 1 and 4 % (in 2 pregnant women) of group 1.

Mean values of the pulsation index (PI) of blood flow velocity curves in the uterine arteries (UA) and umbilical cord artery (UCA) in pregnant women with RHG were higher than the standard average for gestational age.

In pregnant RHGs, a history of various types of fetal growth retardation (FGR) is detected. The number of early forms of URP was higher in group 1 (16.7 %, i.e. in 10 pregnant women) as opposed to group 2 (2.0 %, i.e. 1 case). The late form was approximately the same amount in both groups. Also, group 1 was characterized by a significantly larger number of FGR of 2-3 centuries.

In addition, in both groups with RHG, such pathological conditions were identified during pregnancy as the threat of premature birth, premature placental maturation, placental hypoplasia, oligohydramnios, and hydramnios.

Conclusions. Pregnant women with recurrent RHG compared to pregnant women with sporadic RHGs have a greater number of complications during pregnancy, including the threat of preterm labour, premature placental maturation, placental hypoplasia, oligohydramnios, hydramnios, FGR, impaired uterine-placental and placental-fetal blood flow.
