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.

The results of this study suggest that FVL and PGM presence in asymptomatic women and in the absence of other risk factors do not influence IVF outcome, or represent risk factors for ovarian hyperstimulation syndrome (OHSS), or favour thrombosis after IVF. Screening for FVL and PGM does not appear to be justified to identify the patients at the risk for IVF failure, and/or for OHSS, and/or for thrombotic complications.

The clinical utility of Doppler blood flow investigations of the fetal and fetoplacental vessels is still under debate as far as timing of the delivery is concerned. However, in cases of absent or reverse end-diastolic flow, fetal compromise is usually very severe. As a consequence, we have investigated the possibility of using this information as a guide to obstetrical management. Altogether, 32 fetuses with absent or reverse end-diastolic flow in the fetal descending aorta and/or umbilical artery were studied. Reverse flow was observed in 11 cases and absence of end-diastolic flow in 21 cases. The two groups are considered separately. No significant difference was found in the mean gestational age at delivery. However, a highly significant difference was found in the mean birth weight and perinatal mortality rate. All the cases of perinatal mortality were encountered in the group presenting with reverse flow (mortality rate, 63.6%). All the live fetuses were delivered by Cesarean section and no neonatal mortality was observed in this group. Two cases of handicap were observed, one in each group. In our experience, reverse flow indicates the necessity for immediate delivery if no other clinical contraindications are present. Absence of end-diastolic flow can be observed for longer periods without adverse outcome. Absence of end-diastolic flow always precedes the appearance of fetal distress. Therefore, we believe that, after exclusion of conditions such as fetal abnormalities or extreme prematurity, a planned delivery should be considered.
