SUMMARY AND CONCLUSIONS
The objective of this work was to study the pattern of the
umbilical artery blood flow in pregnancies complicated by PIH.
DM and IUGR.
The ultimate goal was to assess the capability of the
Doppler ultrasound as an antepartum surveillance test in the
expected management of high risk pregnancy and to detect early
fetal compromise.
125 pregnant cases were included in this study, divided into
4 groups>
ajl’regnancy induced hypertension (25 cases) .
b) Diabetes Mellitus (25 cases).
c) Intrauterine growth retardation (25 cases).
d)Control group (50 cases).
Ccmplete history taking, thorough clinical examination and
ultrasound fetal assessment were done in all cases.
7\.
Continuous Doppler ultrasound examination of umbilical
artery was done.
The mean SID ratio was calculated and RI . The results were
classified into 3 groups : normal SID ratio was less than 3.
increased SID ratio when more than 3 and lastly absent or
revesed end diastolic tlow.
In PIH cases with abnormal urnblical artery tlow velocity
waveforms showed a significant higher value of mean systolic
and diastolic blood pressure. Also. the same cases showed a
significant higher values of mean serum uric acid and a
significantly lower mean platelet counts.
In diabetic group, Doppler velocimetry findings were
abnormal in cases assossiated with vasculopathy.
In IUGR group, abnormal Doppler findings were found in
80% of the cases. So, Doppler ultrasound is useful in diagnosis
and prediction of IUGR .
This survey of different mode uses of Doppler scanning to
date, illustrates the considerable part it now plays in obesterical
monitoring.

Although recording the Doppler signal of umbilical arteries in
normal pregnancy may not be thought necessary. It is now
recognized out this examination in high risk pregnancies is
essential if possible it slould be complememted by examination
of the cerebal arteries in cases of suspected intrauterine growth
retardation.
