“…The score is classified as either normal (8-10 points), suspicious (5-7 points) or pathological ( < 5 points). The antenatal diagnosis of 1UGR was made on the basis of ultrasound growth charts of the biparietal and the transverse abdominal diameter accord ing to Hansmann et al [8] when at least one value was below the 5th centile.…”

In 30 of 137 high-risk pregnancies we observed absent end-diastolic velocities indicating a high downstream impedance, which could be proved by histomorphological findings of the placenta. On the average the loss of end-diastolic velocities occurred 2–3 days before suspicious and nearly 8 days before pathological cardiotocographic findings. The perinatal mortality was high when absent velocities had been observed before the 32nd week, a cesarean section was obligatory in all but 1 case. All fetuses were growth-retarded. In 9 cases we were able to determine the ratio of blood flow volume in the common carotid arteries to that of the fetal aorta. The values were significantly increased as compared to values of undisturbed pregnancies, demonstrating a redistribution of fetal blood in favor of cerebral circulation.

For the visualization of the uterine cavity hysterography (HG) is an established procedure. Hysterosonography (HS) is a new imaging modality. In an in vitro study the features of HS have been compared to those of HG. The results of both methods were verified by macroscopic and microscopic specimen. HS is su-I maging systems for visualizing the uterus have gained more and more importance. Percutaneous ultrasound, computed tomography, and magnetic resonance imaging are already established procedures.1·3 In the visualization of the uterine cavity, its size, form, and pathologic changes are important in the diagnosis and therapy of infertility and uterine tumors. Hysterography (HG) has been the diagnostic procedure of choice.4 Over the last few years, hysterosonography (HS) has broadened the diagnostic spectrum. HG allows the visualization of the uterine cavity and provides additional information concerning cavity-related processes. HS allows a visualization of the macroscopic fine structure of the uterus, the uterine cavity, the endometrium, the myometrium, and the serosa . 5 In this in vitro study we investigated the diagnostic value of HG and HS for the evaluation of benign or malignant uterine diseases. With both methods, measurements were carried out with macroscopic and histologic specimens and correlated to each other. MATERIALS AND METHODSIn an 18-month period we examined 50 uteri. The fresh specimens underwent HS and HG. The histologic re· suits are listed in Table 1. HysterographyThe uterine cavity was filled with 4-8 ml Urovist (Schering) using a syringe directly inserted into the cervical channel. In cases of a significant reflux, the cervix was tied together with a pin. We used a Mammomat (Siemens, Erlangen, West+Germany) with 28 kV in anteroposterior projection. The geometric arrangement and the specimen/film-source distance were standardized. HysterosonographyHS was performed with an SSD 500 (Aloka, Tokyo, Japan) with a transurethral transverse scanner (ASU 52). The frequency used was 7.5 MHz. After dilatation of the cervical channel to maximal Hegar 9 the scanner was introduced into the uterine cavity up to the fundus. Isotonic salt solution was introduced and transverse sectional images were documented every 0.5 cm from the fundus to the cervix. The location of each docu -

“…From all pregnancies in which IUGR was sus pected in our hospital population during a 2-year peri od, patients were scheduled for intense surveillance, in which the abdominal diameter was less than the 5th centile according to Hansmann et al [5], Retrospec tively, cases were neglected where the last biophysical tests had not been performed within a period of 1-3 days before delivery. The mean gestational age at delivery was 37 + 1 weeks (27 + 4 to 40 + 1 weeks).…”

One hundred and three intrauterine growth retardation (IUGR) pregnancies were scheduled for pulsed Doppler ultrasound of the common carotid and the umbilical artery, non-stress 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.
