Prenatal diagnosis of isolated foramen ovale obstruction. A report of two cases.

Premature obstruction of the foramen ovale is a rare but serious clinical entity. Obstruction can be associated with right ventricular failure, fetal hydrops, tricuspid regurgitation, left heart obstructive defects and supraventricular tachycardia. In most cases, the diagnosis is made at the postmortem examination. The etiology is unknown. We discuss 2 prenatal cases with the sole diagnosis of ventricular asymmetry. The right ventricle was dilated and hypertrophic, and the foramen ovale ballooned into the left atrium without color Doppler detection of right-to-left flow. After delivery, the infants had no hydrops or symptoms of cardiac or respiratory distress. Echocardiography demonstrated a structurally normal heart with increased right ventricle dimensions until the 7th day of life. Delivery should be induced if possible in cases of foramen ovale obstruction with signs of cardiac decompensation.

Prediction of fetal distress and poor outcome in intrauterine growth retardation--a comparison of fetal heart rate monitoring combined with stress tests and Doppler ultrasound.

One hundred and three intrauterine growth retardation (IUGR) pregnancies were scheduled for pulsed Doppler ultrasound of the common carotid and the umbilical artery, nonstress and contraction stress tests (NST/CST) as well as vibroacoustic stimulation tests (VAST). The last examinations < 3 days before birth were compared by receiver-operator characteristics: Results of the resistance indices of fetal common carotid/umbilical artery and NST were more predictive of later fetal distress during labour, compared to CST and VAST (p < 0.001/< 0.01). Similar results were found for the prediction of low pH and Apgar values, though differences were less pronounced. Our results suggest that stressful examinations should be abolished from mother and fetus in the supervision of IUGR.

Successful treatment of primary fetal hydrothorax by long-time drainage from week 23. Case report and review of the literature.

We report on a case of unilateral primary fetal hydrothorax leading to nonimmunological fetal hydrops (NIHF). The NIHF was treated successfully by inserting two consecutive intrauterine catheters at 23 weeks gestation. The first catheter was dislocated through the uterine wall to the maternal peritoneal cavity. At 36 weeks gestation, the mother had a spontaneous onset of labor after premature rupture of membranes and a normal vaginal delivery of a healthy infant with good perinatal outcome. Shunting of PFHT has rarely been described up to now. This case report supports observations of previous authors that early shunting of pleural effusions may prevent progression of NIHF as well as postnatal pulmonary hypoplasia. Unexpected perinatal complications of fetus, mother or both should not be neglected.

[Effect of maternal age on the course of labor--analysis of women over 40 years of age].

In order to determine the birth risk for pregnant women in the age group > or = 40, the delivery data of 143 pregnant women in this age group were retrospectively evaluated over a 3-year period. Here, 37 of these 143 women (25.9%) were primiparae. The following was examined: The number of prenatal examinations (including ultrasound examinations), the incidence of genetic examinations, the delivery methods with the percentage of surgical deliveries, complications at the time of delivery as well as the fetal outcome with APGAR values, umbilical artery pH, birth weights, neonatal morbidity and mortality. The delivery results were compared with representative populations of women between 20-29 years (n = 2252) and 30-39 years (n = 1980). Pregnancy in older women still ends significantly more often with cesarean section than in younger women. Here, the rate of cesarean sections was 32.7% compared to 21.9% in 30-39-year-olds and 15.8% in 20-29-year-olds. However, parity has an even greater influence on the mode of delivery than age. Only 30.1% of multi-parae over 40 years underwent surgical delivery (vaginal and abdominal) compared to 77.3% of primiparae. It was also found that multiparae more rarely had surgical delivery than younger primiparae (30-39 years 53.3%, 20-29 years 39.3%). Despite the high surgical delivery rate being in the group of primiparae over 40 years, the fetal outcome was comparatively poor, so that the less restrictive indication for surgical delivery seems justified.
