Abstract:
The aim of this study was to examine the value of one step
uterine artery Doppler at first and second trimester of pregnancy
in the prediction of PIH (Pregnancy Induce Hyperion) and/ or
intra uterine growth restriction (IUGR). Uterine blood flow
study resistance index (R1) and pulsitility index (PI) of uterine
artery were calculated.
This is a cross sectional hospital based control study
conducted in Alturky Hospital (outpatient clinic) from 2014 to
2015. The study included 50 women with singleton pregnancies
at 12- 24 weeks of gestation who had history of PIH, low birth
weight fetus and, or unexplained prenatal fetal death in their
previous pregnancy.
The study shows that (30%) of this study population had high
(R1) and (P1) with low blood flow. Most of cases (73%) > 14
weeks of gestation, with average age of 37 years old PIH was
the most frequent risk factor.
Doppler ultrasound provided more accurate prediction when
performed in the second trimester than in first trimester an
increased resistivity and pulstility index alone or with notching
was the best predictor of PIH among high risk patients and it is
the most predictive Doppler indices.
