Comparative study of clinical features and pregnancy outcomes of intrauterine subchorionic hematoma and retroplacental hematoma / 中国医师进修杂志

ABSTRACT

Objective@#To explore the clinical features and pregnancy outcomes of intrauterine subchorionic hematoma and retroplacental hematoma.@*Methods@#From May 2016 to May 2018, in the Fourth Hospital of Xi′an City, 110 cases of intrauterine hematoma were selected in the middle of pregnancy, including 52 cases of subchorionic hemaloma (group A) and 58 cases of retroplacental hematoma (group B). The clinical features and pregnancy outcomes of the two groups were compared.@*Results@#The volume of hematoma in group B was significantly smaller than that in group A [(8.8 ± 1.7) cm3 vs. (18.3 ± 2.0) cm3], the gestational weeks of group B was also significantly lower than that of group A [(35.2 ± 2.1) weeks vs. (38.4 ± 1.8) weeks], the full-term pregnancy rate in group B was lower than that in group A[56.9%(33/58) vs. 84.6%(44/52)], miscarriage rate and premature birth rate were higher than those in group A [20.7%(12/58) vs. 5.8%(3/52), 22.4%(13/58) vs. 7.7%(4/52)], and the differences were statistically significant (P < 0.05).The incidence of fetal distress in group B was higher than that in group A [17.4%(8/46) vs. 2.0%(1/49)], the incidence of fetal membrane rupture, placental abnormality, and placental residue was all higher than that in group A[41.3%(19/46) vs.10.2%(5/49), 37.0%(17/46)vs.12.2%(6/49), 28.3%(13/46) vs. 6.1%(3/49)], and the differences were statistically significant (P < 0.05). The neonatal body mass in group B was lower than that in group A [(3 091.7 ± 887.6) g vs. (3 457.6 ± 560.2) g], and the incidence of neonatal diseases was higher than that of group A [15.2%(7/46) vs. 2.0%(1/49)], and the differences were statistically significant (P < 0.05).@*Conclusions@#The volume of hematoma and gestational weeks of intrauterine retroplacental hematoma are lower than those of subchorionic hematoma, and the retroplacental hematoma is more likely to have adverse pregnancy outcomes.
