Influence of acupuncture on Doppler ultrasound in pregnant women.

OBJECTIVE: To evaluate the influence of acupuncture on the blood flow in the umbilical artery (UA), fetal aorta and uterine artery and on the fetal heart rate using two different acupuncture points (SP-6 (Sanyinjiao) and LI-4 (Hegu)). METHODS: In group A (n = 50), measurements (Doppler ultrasound and fetal heart rate) were performed at term after an uneventful pregnancy (#1) followed by acupuncture treatment using the acupuncture-point SP-6 bilaterally. The treatment time lasted 15 min after which the next measurement (#2) was carried out. The needles were then inserted into the LI-4 acupuncture point for a further 15 min. A third measurement at the end of acupuncture treatment (#3) completed the session. In group B (n = 25), measurements were made before (#1) and after (#4) acupuncture at LI-4 acupuncture points only. RESULTS: In group A, the mean systolic/diastolic (S/D) ratios of UA #1, UA #2 and UA #3 were 2.45, 2.38 and 2.22, respectively (P = 0.0012). The difference in mean S/D ratios between UA #1 and UA #3 as well as that between UA #2 and UA#3 were statistically significant (P = 0.0002 and P = 0.008, respectively). There was no difference between the mean S/D ratios of the uterine artery and between the mean resistance indices of the fetal aorta. In group B, the only significant difference between measurements following acupuncture treatment was in fetal heart rate (139 vs. 143 bpm, P = 0.02). CONCLUSION: Our study indicates a positive influence of acupuncture treatment on umbilical artery waveforms when using a combination of SP-6 (Sanyinjiao) and LI-4 (Hegu) acupuncture points. Acupuncture performed at these sites either individually or in combination does not seem to affect blood flow in the fetal aorta or uterine artery.

Combined prenatal ultrasound and magnetic resonance imaging in two fetuses with suspected arachnoid cysts.

Sonography and ultrafast magnetic resonance imaging were used in the prenatal assessment of two fetuses with sonographically suspected arachnoid cysts. In one case magnetic resonance imaging confirmed the ultrasound diagnosis, in the other case magnetic resonance imaging revealed the presence of a midline cyst associated with dysgenesis of the corpus callosum. Ultrafast magnetic resonance imaging is a useful supplementary imaging method in the evaluation of pregnancies complicated by fetal cerebral anomalies.

[Prenatal diagnosis of full, non mosaic trisomy 22 in the third trimester].

A 31-year-old Caucasian women was referred to our department after IUGR was suspected by her gynaecologist at 29 weeks' amenorrhea in her second pregnancy. Multiple anomalies were detected by prenatal ultrasound in the 29th week of gestation. Chordocentesis was performed and revealed a Trisomy 22 in all fetal blood cells. The pregnancy was terminated. Post-mortem investigations excluded chromosomal mosaicism. Prenatal ultrasound findings and post-mortem features are presented.

Evaluation of first trimester pregnancy in cases of threatened abortion by means of doppler sonography.

OBJECTIVE: Threatened abortion is one of the major problems in Obstetrics and applies to (1/3) of all pregnancies. The aim of this study was to establish normal ranges for Doppler indices of the flow velocity waveforms in uterine arteries (S/D, RI, PI) and ss-hCG serum concentrations in a control group in the first trimester of pregnancy. The obtained values were compared with those obtained in pregnancies threatened by abortion (6 - 11 weeks). METHODS: Investigated groups: 55 controls and 47 with symptoms of threatened abortion, 27 of them aborted. Ultrasound examinations were carried out by means of an endovaginal probe. Serum ss-hCG was determined by immunoenzymatic method. The standards for measured values were established based on means from measurements obtained in the control group in the corresponding week of pregnancy. RESULTS: We observed negative correlation between gestational age and RI and negative tendencies for S/D and PI indices in the control group. Positive correlation (p < 0.05) was found between ss-hCG serum concentration and gestational age (up to 9(th) week) and significant differences in ss-hCG concentrations between both examined groups. There were also statistical differences for S/D, RI and PI indices in both analyzed groups for each week of pregnancy. CONCLUSION: We conclude that measurement of the quality parameters of the flow velocity waveforms in uterine arteries and calculation of beta-hCG concentration in serum are useful methods in diagnosis of threatened abortion in the first trimester of pregnancy.

The value of echogenic foci ('golfballs') in the fetal heart as a marker of chromosomal abnormalities.

OBJECTIVE: The aim of our study was to determine the significance of antenatally detected hyperechogenic foci in the fetal heart. DESIGN: Prospective study. SUBJECTS AND METHODS: During a 21-month period, 6995 women underwent a sonographic screening investigation. A detailed structural survey was performed on each fetus according to our sonography protocol, including a four-chamber view and an evaluation of the great vessels, as permitted by gestational age. We prospectively identified each fetus with an echogenic intracardiac focus. RESULTS: A total of 150 fetuses with this sonographic finding were identified. The incidence rate was 2.15%. In 114 patients (76%), prenatal karyotyping was performed. The aneuploidy rate was 4.4%. CONCLUSIONS: The echogenic intracardiac focus can be easily diagnosed in most cases. This should prompt an extensive search for other 'soft' markers. The presence of an echogenic intracardiac focus as a single soft marker should raise the question of prenatal karyotyping. It might help in the decision-making regarding invasive prenatal testing in cases with an otherwise low risk for chromosomal abnormality. In cases with other markers for chromosomal abnormality (advanced maternal age, sonographic signs, positive serum marker screening), the presence of an echogenic intracardiac focus should be an additional incentive for a chromosomal examination.

[Echogenic intracardiac structures (golf ball phenomenon) as predictors of chromosome anomalies].

UNLABELLED: Small echogenic areas in the fetal heart are known as the golf ball phenomenon. These structures are considered by some to be a marker for chromosomal anomalies. AIM: To prospectively study the relationship of echogenic intracardiac structures and chromosomal aberrations. METHODS: Over a 15 month period (6/96-9/97) 4500 unselected fetuses between 16-31 weeks were screened for malformations; in each case echogenic intracardiac structures were sought. RESULTS: In 77 cases (1.17%) single or multiple echogenic punctate intracardiac structures could be diagnosed. In 60 fetuses (78%) chromosome analysis was performed. Two (3.3%) had chromosomal abnormalities--trisomy 21 and 45.XO/46.XX. CONCLUSION: The golf ball phenomenon appears to be a normal variation in the development of the papillary muscle. This sign is usually easily to identify and if present, should lead to a more detailed screening for anomalies. In the case of other sonographic abnormalities, with advanced maternal age or with a positive triple test, a chromosomal analysis should be performed.

Isolated Dandy-Walker malformation: prenatal diagnosis in two consecutive pregnancies.

We report a family with recurrent Dandy-Walker malformation (DWM). The first offspring was found prenatally to have isolated DWM at 30 weeks' gestation. Ultrasonography at 19 weeks' gestation in the subsequent pregnancy revealed isolated DWM in both dizygotic twins. Chromosome analysis was normal in all three infants, and autopsy confirmed that no other congenital abnormalities were present. Evidence suggests that rare families transmit the disorder in an autosomal or X-linked recessive pattern, with a high recurrence risk.

An undetected reason for severe fetal growth retardation.

In a severely growth-retarded fetus, repeated Doppler ultrasound examinations from the 23rd week of gestation on, showed normal and highly pathological blood flow velocities in the umbilical artery. A caesarean section performed in the 39th week of gestation revealed two true umbilical cord knots. Sonographic screening for umbilical cord knots may be valuable in similar cases. The use of color Doppler could help to visualize the entire course of the umbilical cord.

Cystic adenomatoid malformation of the lung: prenatal diagnosis, prognostic factors and fetal outcome.

AIM: To evaluate 14 cases of cystic adenomatoid malformation (CAM) of the lung with regard to antenatal management and fetal outcome. RESULTS: Intrauterine shunts were placed in 3 fetuses to avoid pulmonary hypoplasia. Prenatal sonography showed that the lesions had a tendency to resolve in 4 cases. Of the 9 infants who survived, 5 were treated surgically (lobectomy). CONCLUSIONS: The antenatal evolution of these lesions is highly variable; the lesions may even resolve spontaneously, therefore the diagnosis of CAM types II and III should be followed by a period of observation. Intrauterine drainage is recommended in cases of CAM type I if unfavorable prognostic factors are encountered.

Endometrial volume change during spontaneous menstrual cycles: volumetry by transvaginal three-dimensional ultrasound.

OBJECTIVE: At present, only limited data are available on endometrial volume during the menstrual cycle. Most of these studies deal with animal models and use magnetic resonance imaging for volume measuring. The application of three-dimensional ultrasound in endometrial volume estimation is the subject of this study. SETTING: Patients visiting the outpatient unit of the division of endocrinology and reproductive medicine of a university hospital. PATIENT(S): Twenty patients with a history of a normal menstrual cycle were selected. INTERVENTION(S): Ultrasound examinations were performed during a single menstrual cycle in addition to routine laboratory tests. MAIN OUTCOME MEASURE(S): Uterus-endometrial volume ratio. RESULT(S): Data from 18 patients could be evaluated. In 81 examinations the endometrium volume could be determined. Mean endometrial volume measured by three-dimensional ultrasound was 1.23 cm3. Mean uterus volume was 48.93 cm3. The change of the uterus-endometrial volume ratio showed a good correlation with the day of menstrual cycle. Quadratic regression analysis of volume and cycle length was R2 = 0.432. CONCLUSION(S): Three-dimensional ultrasound allows assessment of volume data of the female internal genitalia. In this study changes of the endometrial volume in menstrual cycles were measured. Additional studies are required to give information on the clinical impact of this new technique of endometrial volume estimation.

Umbilical artery Doppler velocimetry in fetuses with a single umbilical artery.

OBJECTIVE: Doppler waveform analysis of the umbilical artery is an important tool for the evaluation of high-risk pregnancies. Yet, available data are based on normal values from three-vessel umbilical cords. Our purpose was to evaluate the value of umbilical artery Doppler velocimetry in fetuses with a single umbilical artery. METHODS: One hundred thirteen consecutive singleton fetuses with a single umbilical artery between 16 and 40 weeks' gestational age were studied prospectively at a tertiary referral center for prenatal diagnosis and therapy. Complete follow-up was obtained from 103 cases. RESULTS: The systolic-diastolic ratio in the umbilical artery was abnormal in 31 fetuses (30%) and normal in 72 fetuses (70%). Fetuses with abnormal Doppler waveform analysis in the umbilical artery were significantly more likely to be growth restricted (55 compared with 15%), to have complex malformations (58 compared with 1%) or an abnormal karyotype (29 compared with 0%), or not to survive the fetal/perinatal period (42 compared with 0%) than those with normal Doppler waveform analysis. CONCLUSION: Fetuses with a single umbilical artery and abnormal umbilical Doppler velocimetry had a significantly increased risk of adverse fetal and neonatal outcome compared with those with a single umbilical artery but normal Doppler studies.

Spontaneous rise of fetal platelet counts despite increasing anti-HPA-5b antibodies.

BACKGROUND AND OBJECTIVES: Maternal anti-HPA alloantibodies are a rare cause of severe fetal thrombocytopenia. So far there have been no reports on the dynamics of maternal anti-HPA-5 during gestation and its effect on the fetus. MATERIALS AND METHODS: We monitored maternal anti-HPA-5b antibody titers and fetal platelet counts during gestation in a woman with known anti-HPA-5b alloimmunization. The patient was a 32-year-old woman in her third pregnancy. The 1st pregnancy and delivery of a healthy child had been uneventful. At delivery, anti-HPA-5b was detectable in the maternal serum. A 2nd pregnancy ended in early miscarriage. RESULTS: A steady rise in the alloantibody titer was recorded throughout the 3rd pregnancy. Therefore, cordocentesis was performed at 28 weeks of gestation (platelet count 76 x 10(9)/l). Serial platelet transfusions were administered to the fetus at 28, 32, and 37 weeks of gestation. The platelet counts rose spontaneously thereafter and were 220 x 10(9)/l at delivery, despite an increase in the anti-HPA-5b antibody titer. The child developed normally during the first year of life. CONCLUSIONS: This case illustrates the spontaneous recovery of fetal platelet counts in late pregnancy despite a rise in maternal alloantibody titer.

Dandy-Walker malformation diagnosed before 21 weeks of gestation: associated malformations and chromosomal abnormalities.

This study examined rates of concomitant structural and chromosomal abnormalities in 14 fetuses with a diagnosis of Dandy-Walker malformation or Dandy-Walker variant before 21 weeks' gestational age, compared to 14 fetuses with a diagnosis of Dandy-Walker malformation or variant between 21 weeks' gestation and delivery. A total of 24 fetuses had Dandy-Walker malformation and four had Dandy-Walker variant. Eight of the fetuses with the malformation had ventriculomegaly: one of the fetuses with early diagnosis and seven with later diagnosis (p = 0.027). None of the fetuses with Dandy-Walker variant had ventriculomegaly. The overall prevalence of concomitant structural abnormalities was 13/28; 8/14 for fetuses with early prenatal diagnosis and 5/14 for fetuses with late prenatal diagnosis of the malformation or the variant. Chromosomal abnormality rates were significantly higher among fetuses with early prenatal diagnosis (7/14) than among those with later prenatal diagnosis (1/14; p = 0.032). Abnormal karyotypes were more prevalent among fetuses without ventriculomegaly (7/20), compared to fetuses with ventriculomegaly (1/8). We conclude that fetuses with an antenatal diagnosis of Dandy-Walker malformation or Dandy-Walker variant before 21 weeks' gestational age have worse prognosis than fetuses with a later prenatal diagnosis of the same defect.

Intrauterine device localization by three-dimensional transvaginal sonography.

Our objective was to investigate the possible role of three-dimensional transvaginal ultrasound in the visualization of an intrauterine device (IUD) for routine follow-up after insertion. A total of 96 women were examined after insertion of a TCu380A IUD. Three-dimensional ultrasonographic imaging was carried out using a special vaginal probe and a commercially available ultrasound machine at a mean interval of 22 days after insertion. Complete simultaneous imaging of all parts of the IUD was possible in 95% of cases. In the three-plane mode, all parts of the IUD could be visualized in 64% and in a further 30 cases this was possible only after volume rendering. In two women, incomplete opening of the two arms of the device was demonstrated. In one of these cases, the entire IUD was displaced into the cervical canal. In another case, an intrauterine pregnancy was found together with an IUD in the correct position. Three-dimensional ultrasound provides useful information on the location of the IUD following insertion. It enables imaging of the entire IUD, i.e. the shaft and the arms, simultaneously. Additionally, the examination time can be kept to a minimum with this new technique.

The influence of the experience of the investigator on the rate of sonographic diagnosis of fetal malformations in Vienna.

The quality of prenatal ultrasound may be influenced by different factors. In this study, the influence of the experience of the investigator on the quality of routine ultrasound screening during pregnancy was evaluated. We related the detection rate of fetal malformations in routine ultrasound screening in the region of Vienna to the experience level of the examiner. All 323 cases of fetal malformations registered by the obstetrical departments of Vienna or registered by the Vienna perinatal mortality statistics of 1990 and 1991 were evaluated. For analysis we used the medical charts or the patient-held antenatal records ("Mutter-Kind-Pass'). Obstetricians in private offices (level I) detected 22 per cent, the examiner in the hospital (level I-II) 40 per cent, and the examiner in the centre for prenatal diagnosis and therapy (level III) 90 per cent of all fetal malformations. The detection rate before the 24th week of gestation was significantly different (25 per cent vs. 34 per cent vs. 58 per cent). Our results suggest that an important factor for the quality of prenatal ultrasound investigation is the education of the sonographers. Furthermore, each pregnant woman should undergo ultrasound screening once in a level II or III centre before 24 weeks or before fetal viability.
