Assessment of Uterine Artery in Pregnancy Induce Hypertension by Using Colour Doppler

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.
