Absent/Reverse Flow in Umbilical Artery Doppler – A Very Poor Prognosis

Arya A, Stuart B, Daly S

Coombe Women’s Hospital, Dublin

Objective: From a tertiary referral unit with more than 8000 births a year and a corrected perinatal mortality rate of 5-6 per annum, we report a six year study of outcome data on all women whose pregnancies were complicated with absent or reverse flow in the umbilical artery.

Study design: Using the database generated from the ultrasound department we identified all women whose pregnancies were complicated with either absent or reverse flow in the umbilical artery. The obstetric and paediatric charts were reviewed. Statistical analysis was parametric and nonparametric where appriopiate.

Results: The total number of births over the study period was 45,620.Eighty six cases were identified giving an incidence of 0.19%. The mean gestational age at diagnosis was 30.5 (4.2) weeks. Delivery was as indicated by fetal testing (CTG and Biophysical Profile Score). The indication for the ultrasound evaluation was clinical concern about growth in 78 cases. Fifty three cases (61.6%) were hypertensive. The median birth weight was 1110g, there were 9 infants whose birth weight was <500g and none survived. Nine of the 52 times a cord ph was obtained the value was 7.2 or less. There were ten stillbirths (11.6) and 65 infants were admitted to the SCBU. There were 14 neonatal deaths giving a perinatal mortality rate of 279. The median duration of stay was 41 days (IQR 56). Fifty four (62.7%) of infants were discharged home well

Conclusion: Abnormal umbilical artery Doppler is associated with significant perinatal complications, even when managed and delivered within a tertiary referral unit. While these outcomes are influenced by the gestational age and birth weight intervention options to improve outcomes need to be investigated
The impact of Grannum grade on maternal and fetal wellbeing in the low-risk primigravid population

Aim: To determine the impact of Grannum grade in the late third trimester on maternal and fetal wellbeing in the low-risk primigravid population
Design: 1,011 women were recruited from the antenatal booking clinic in the Rotunda Hospital Dublin during the study period. Inclusion criteria included: caucasian women with a singleton pregnancy, ≤ 20 weeks gestation, 18 to 40 years old, no chronic medical conditions and no current drug therapy. Early ultrasound confirmed gestation. These women were monitored by course of serial ultrasounds during the course of the pregnancy. Fetal wellbeing and placental architecture were assessed between 34 and 36 weeks gestation, and placental grading was performed based on the criteria established by Grannum et al in 1979.

All data while collected prospectively was analysed retrospectively in relation to maternal and neonatal delivery variables. Histological assessment was performed on all placentas, and select cases underwent stereological evaluation.


Results: Of the 1011 women, 775 attended for their third trimester scan. The average gestation at time of scan was 35.4 weeks. There were 245 women with Grannum grade 1, 450 with Grannum grade 2 and 80 women with Grannum grade 3 at the time of scan. Mean uterine PI and RI were similar in all groups, however a slight increase was noted in mean umbilical artery pulsatility indices as Grannum grade increased. In addition, placental thickness increased with increased Grannum grading. When delivery variables were analysed it was noted that as Grannum grade increased both gestation at delivery and fetal weight decreased. Higher instrumental rates were seen in the lower Grannum grading and higher section rates in both grades 2 and 3.
Conclusion: As placental maturation evolved and Grannum grading increased we observed higher umbilical artery pulsatility indices (PI) and increased placental thickness. Higher Grannum grades at 36 weeks were also associated with a decreased gestation at delivery and a reduction in birthweight. Higher caesarean section rates were observed in those with Grannum grades 2 and 3.

Background: Cardiomyopathy, defined as ventricular wall thickening, is a common finding in infants of diabetic mothers. It is possible that this cardiomyopathy may be associated with impaired cardiac function in utero. Cardiomyopathy leads to an increase in overall cardiac weight (cardiomegaly). The study hypothesis is that cardiomegaly is more commonly found in stillborn infants of diabetic mothers than in the non-diabetic population.
Aim: The aim of the study is to report the incidence of cardiomegaly in stillborn normally formed infants of diabetic mothers and to compare this with the incidence of cardiomegaly in stillborn normally formed macrosomic infants (> 90th centile) and stillborn normally formed appropriately grown infants (10-90th centile) without abruption and for whom no cause of SB was identified.
Methods This is a retrospective study with institutional ethics approval. The presence of cardiomegaly was recorded in stillborn infants of diabetic mothers (N=27) and compared with that recorded in stillborn large for gestational age (> 90th centile, n=18) and stillborn appropriately grown (10-90th centile, n=107) non-diabetic infants. Blinded to the clinical details, the histology slides were reviewed to measure cardiac wall thickness and to record the presence or absence of myocardial fibre disarray.
Results: Stillborn infants of diabetic mothers, when compared with appropriately grown stillborn non-diabetic infants and adjusted for birth weight, had heavier hearts, thicker ventricular free wall measurements and lighter brains. While cardiomegaly was reported in 22% of stillborn large for gestational age infants, comparison with stillborn appropriately grown infants revealed no difference in heart weights after correction for birth weight.
Conclusions: Cardiomegaly is a common finding in stillborn infants of diabetic mothers and may contribute to the risk of fetal death in these pregnancies. Myocardial disarray does not appear to be a constant histological characteristic of diabetic related fetal cardiomegaly.

Introduction: Intensive care therapy for babies with congenital diaphragmatic hernia (CDH) has been augmented progressively over the last 15 years from standard intensive care (SIC) to incorporate the following management strategies: extracorporeal membrane oxygenation (ECMO), high frequency ventilation (HFV), inhaled nitric oxide (iNO), and other strategies geared towards protecting the hypoplastic lung and supporting the cardiovascular system. It is unclear if the use of such therapies has improved survival.
Aim: To describe survival in infants with CDH over five eras defined by distinct changes in management strategies between 1981 and 2005.
Methods: All newborns with CDH admitted to the RCH Neonatal Unit were identified from hospital and departmental databases. No infant was excluded from the analysis for any reason. Five eras are described which were characterised by time periods when newer therapies became widely used in our unit.
