Thirteen fetuses with abdominal cystic tumors were diagnosed by routine prenatal ultrasonography between the 28th and 36th week of gestation. Postnatal ultrasonography of the full-term newborns confirmed the findings. Laparotomies were performed in all cases except one. Patients who were operated on had large ovarian pseudocysts with volumes between 24 and(More)
In a retrospective analysis, presentation behavior during pregnancy of 501 infants with breech presentation at birth was compared with that of a control population (n = 520) with vertex presentation at birth. Since the fetus usually changes position frequently during the sonographic examination prior to the 20th week of pregnancy, and since its presentation(More)
OBJECTIVE The article presents a retrospective analysis (1989-1997) of the prenatal diagnosis, the course and completion of pregnancy of 26 fetuses with omphalocele and 18 fetuses with gastroschisis. SUBJECTS 44 pregnancies with anterior fetal wall defect diagnosed by prenatal ultrasound, clinical or patho-anatomic examination between 1989 and 1997 at the(More)
The aim of this study was to investigate responses of human fetuses near term (37-42 wks) (increase/decrease of fetal heart rate and/or fetal motility) to acoustic stimuli. The study group consisted of 43 patients and the control group of 27 patients. Polygraphic recordings of 5 different fetal variables were carried out synchronously for the categorization(More)
Of 1950 pregnant patients (2870 Doppler ultrasound measurements) we observed, in a study group with highly abnormal Doppler-flow findings (n = 66, Feb. 1990), a correlation of Doppler flow and FHR-recordings. Among these 66 patients we retained 60 (91%) in the hospital. They had at least 2 FHR-recordings a day. The results of Doppler flow measurements in(More)
A total of 2741 high-risk pregnant mothers underwent invasive prenatal procedures, and in 94 of them (3.4%), fetal chromosomal or genetic anomalies were detected. In this study, we report on single pericentric inversions of chromosome 9 as well as translocations, which constituted 32% (30 of 94) and 16% (15 of 94) of all identified chromosomal or genetic(More)
Between January 1989 and November 1996 we detected a total of 44 cases of anterior abdominal wall defects comprising 29 with an omphalocele and 15 with gastrochisis. The gestational age at antenatal diagnosis of gastrochisis (mean = 17 weeks, 95% CI = 15-19) was significantly lower than for omphalocele (mean = 19.0 weeks, 95% CI = 17-21). Whereas(More)
Our aim was to investigate the contribution of certain antenatally detectable markers leading to the diagnosis of trisomic fetuses we observed over a period of 6 years. In our study, we specifically analyzed the role played by advanced maternal age and sonographically discovered abnormalities in the detection of autosomal trisomies. All together, 27 fetuses(More)
The foetal haemoglobin (HbF) content was determined before and 2 hours after amniocentesis in 1,000 cases of amniocentesis conditioned by genetic indication (between the 15th and 20th pregnancy week). HbF-identification was effected according to the method of Kleinhauer and Betke. In primarily (before amniocentesis) negative HbF findings, HbF positive(More)
