Brief Summary
200 women at risk factor for preeclampsia will be subjected to transabdominal Doppler ultrasonography for assessment of placental volume measurements, pulasatility index (PI) and resistivity index (RI) in both uterine arteries, and assessment of the placental volume and its vascular indices (VI, FI, VFI)

Outcome Measures
Primary Outcomes (1)
Development of preeclampsia
Preeclampsia was defined as a blood pressure 140/90 mmHg and proteinuria of 300 mg in 24 hours, or two readings of at least 2+ on dipstick analysis of midstream urine specimens if no 24-hour urine collection was available in absence of urinary tract infection
28 to 38 weeks of gestational age
Study Arms (2)
preeclampsia
women who developed preeclampsia. Preeclampsia was defined as a blood pressure 140/90 mmHg and proteinuria of 300 mg in 24 hours, or two readings of at least 2+ on dipstick analysis of midstream urine specimens if no 24-hour urine collection was available in absence of urinary tract infection
Normal pregnancy
women with normal blood presure
Interventions
Trans-abdominal ultrasound examination was performed with the woman placed in a recumbent or semi recumbent position \& carried out for measurement of fetal CRL and diagnosis of any major fetal defects
measurement of UtA-PI \& UtA-RI. A sagittal section of the uterus was obtained For the Doppler studies, and the cervical canal and internal cervical os were identified. The transducer was gently tilted from side to side and color flow mapping was used to identify each UtA along the side of the cervix and uterus at the level of the internal os. When three similar consecutive waveforms had been obtained the UtA-PI and UtA-RI were measured, and the mean UtA-PI and UtA-RI of the left and right arteries were calculated.
3D transabdominal ultrasound of the Placental volume: the transducer with a full bladder and the transducer placed perpendicular to the placenta to see the entire placenta. The adjustments to 3D placental scan were an angle of 70° and a maximum region of interest that allowed the full placental surface. The external limits of the placenta were defined by the basal plate and the chorionic plate excluding the myometrium. Another acquisition was done, if the quality criteria were not attained. After sonography, the placental volume was calculated with 4D View software (GE Healthcare) by a single operator. The calculation was done twice using the same image, and the time spent was recorded. The VOCAL mode with an angle of rotation of 30° was chosen; the axial plane was the reference; and the calipers were placed on either side of the placenta. With 6 planes, it was possible to reconstruct the volume measured in cubic centimeters.
Eligibility Criteria
women at risk factor of preeclampsia as women with singleton pregnancy especially at the extremes of reproductive age
You may qualify if:
- \. Singleton pregnancy. 2. Familial history of preeclampsia as it has agenetic predisposition. 3. Regular menstrual cycles before pregnancy. 4. Females had preeclampsia in a previous pregnancy. 5. Gestational diabetes or essential hypertension or chronic nephritis with pregnancy" they will be seen between 11 - 14 weeks' of gestation
You may not qualify if:
- \. Cases with fetal anomalies. 2. Dead fetuses
