“…Hofstaetter et al reported uterine artery notch to be a better predictor of perinatal outcome than unilateral high PI. 15 This is in contrast to the findings of Ghosh et al where RI and PI were considered better indicators of vascular impedance in predicting adverse perinatal outcomes. 16 B/L notch in uterine artery Doppler was present in 25.4% participants and this findings are quit comparable with the similar study done by Wald RM et al, Rai L et al but not consistent with study done by Maria AL et al and Li H et al 11,13,14,17 Study found acceptable sensitivity, specificity, PPV and NPV of Doppler ultrasound during third trimester to predict obstetrical and perinatal outcome and this findings are comparable with study done by Rai L et al 13 Limitations of this study was number of cases has been small and study not included Patients who came in labor or with a complication like abruptio placenta.…”

Background: Doppler ultrasound has emerged as beneficial tool in the assessment of the fetal and placental circulation and in the prediction of adverse pregnancy outcome. Umbilical artery Doppler has proved helpful to supervise the growth restricted fetuses and compromised vasculature as in hypertensive disorders high risk pregnancies. Objective of present study was to investigate the association between third-trimester uterine artery Doppler assessment and adverse obstetric outcome.Methods: This prospective study was done among 110 high risk pregnancies. Vessel like uterine artery, umbilical artery, middle cerebral artery and ductus venosus were studied in present study. Indices calculated: Peak systolic velocity, End diastolic velocity, Mean velocity, Systolic/diastolic ratio, Pulsatility index (PI) and resistance index (RI) of middle cerebral artery (MCA), Ductus venosus S/A ratio.Results: bilateral notch was present statistically significant (p<0.05) in 18.1% and absent in 28.2% among cases of adverse perinatal outcome. UA S/D ratio was >3 in 22.7% and <3 in 11.8% among cases of adverse perinatal outcome and findings were statistically significant (p<0.05). End diastolic velocity was reduced in statistically significant (p<0.05) in 9.1% and normal in 20.1% among cases of adverse perinatal outcome. MCA PI was <lower limit statistically significant (p<0.05) in 24.5% and >lower limit in 18.2% among cases of adverse perinatal outcome. MCA PI/UA PI ratio was <1 statistically significant (p<0.05) in 25.5% and absent in 17.3% among cases of adverse perinatal outcome.Conclusions: Increase in UA PI and decrease in MCA PI are early marker for detection of fetal compromise. Ratio of indices between MCA PI and UA PI reflects brain sparing effect as well as placental insufficiency and these are more specific in detection of IUGR than individual artery indices.

“…The transformation of subplacental arteries is normally complete at 20-24 weeks of gestation [16]. Impedance in the uterine artery decreases gradually during vessel transformation and is stable after 24 weeks of gestation in normal pregnancy [17,18]. Increased uterine artery impedance beyond 20-24 weeks of gestation has been reported to reflect abnormal placentation and relate to the development of preeclampsia [19].…”

Preeclampsia before 20 weeks of gestation: a case report and review of the literature

et al. 2014

The occurrence of preeclampsia before 20 weeks of gestation is rare and usually associated with trophoblastic diseases or antiphospholipid syndrome. Here, we report a case of preeclampsia before 20 weeks of gestation in the absence of the aforementioned disorders. A healthy 30-year-old nulliparous woman presented with new onset of hypertension and proteinuria at 18 weeks of gestation. Fetal ultrasound did not reveal any abnormalities. Empirical steroid treatment was initiated based on a tentative diagnosis of underlying renal disease. The clinical course of the disease was progressive despite steroid treatment and the fetus died in utero 8 days after the initiation of treatment. Following delivery, a renal biopsy was performed and provided a diagnosis of preeclampsia. All symptoms resolved postpartum. This report demonstrates that preeclampsia may occur before 20 weeks of gestation and should always be considered in the differential diagnosis of pregnant women with new onset of hypertension with proteinuria. Previous published cases are summarized briefly.

Uterine artery color Doppler assisted veloeimetry and perinatal outcome

Abstract: The addition of color Doppler imaging to pulsed wave Doppler ultrasound recording of uterine artery blood velocity improves the predictive value of blood velocity waveforms with regard to the perinatal outcome.
