The intrauterine hematoma: diagnostic and clinical aspects

Sixty-two cases of intrauterine hematoma (IUH) with a live fetus have been described. This condition was found in 11% of cases that presented with bleeding in early pregnancy. The rate of spontaneous abortion in this series was 12.9%, similar to that observed in cases of threatened abortion without observable hematoma. Spontaneous abortion and delivery rate before 35 weeks of pregnancy were correlated with the calculated volume of the hematoma. Fetal growth retardation seemed to be increased after observation of IUH, especially when the placenta was located on the posterior uterine wall. Uterine malformations and myomas were likely to represent a predisposing factor for IUH.
