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.

La porpora trombocitopenica autoimmune è una patologia rara e grave che può insorgere in gravidanza. La paziente è stata sottoposta a terapia cortisonica e con immunoglobuline sclavo in preparazione all'intervento di taglio cesareo elettivo.In mancanza di un recupero dei valori delle piastrine, sono state somministrate tre unità di piastrine da diaferesi, da unico donatore. Eseguito taglio cesareo elettivo alla XXXIV settimana, non si sono avute complicazioni del decorso post operatorio della paziente. La neonata del peso 2550gr. ha avuto un normale outcome neonatale.

Background The aim of this study is to review all the cases of FCV diagnosed in the Obstetric and Gynecology Unit of our Institution from 1990 to 1999 and to evaluate the neonatal outcome. Method This is a retrospective study. The diagnosis of ventriculomegaly is according to Cardoza criteria and to atrial width ≥ 10 mm between 15 and 40 weeks gestational. For all cases we consider: progression and/or resolution; association with other fetal ultrasound signs of malformations and with chromosomal abnormalities; fetal infections (TORCH); pregnancy termination and follow-up by pediatric report. In cases of interruption of pregnancy we evaluate postmortem examination. Results Among 165 cases of FCV, n 84 (50.9%) are associated with malformation of SNC, n 59 (35.76%) are isolated, n 22 (13.33%) are associated with other fetal malformations. In the group of isolated: 32 case are borderline (≤ 15 mm), chromosomal abnormalities are 4 among 40 evaluated (10%), favourable neonatal outcome is present in 22 cases of 29 born (75.86%). Conclusions In this study the percentage of chromosomal abnormalities in the FCV isolated is higher than other series in the literature. The reproducibility of measurement of atria rather permits comparisons than other qualitative and quantitative signs.
