INTRODUCTION Hypertensive disorders of pregnancy contribute greatly to maternal and perinatal morbidity and mortality globally, particularly in developing countries. Pre-eclampsia is characterized by hypertension and significant proteinuria during pregnancy. Doppler ultrasonography is an important noninvasive and quick technique that can detect Intrauterine growth restriction (IUGR) at an early stage and reliably predict any adverse perinatal outcome in hypertensive pregnancies. Doppler velocimetry of the umbilical artery and middle cerebral artery strongly correlate with pregnancy outcome. In this study we have done Doppler indices of middle cerebral artery at the time of presentation of pre- eclampsia. AIM AND OBJECTIVE To evaluate the role of Doppler velocimetry in predicting fetal outcome in patients with pre-eclampsia in singleton pregnancies using doppler indices of Middle cerebral artery at the time of presentation. MATERIALS AND METHODS A single centric observational descriptive study was conducted for a period of 18 month from June 2017 to November 2018 using Siemens ACUSON S2000 color Doppler diagnostic system with curvilinear probe array with frequency 3.5MHz. 50 pre-eclampsia patients were enrolled into the study. Prior institutional ethics committee clearance was obtained for study. Informed consent was obtained from subjects for inclusion of their test result in study. Reference studies were used.

This observational type of descriptive study was carried out in the Department of Radiology and Imaging, BIRDEM selecting 70 Bangladeshi pregnant babies with the aim to find out the normogram of foetal middle cerebral artery Doppler flow velocity indices and correlation between Doppler flow velocity indices [Resistance Index (RI), Pulsatility Index (PI), Systolic/Diastolic ratio (S/D) & Peak Systolic Velocity (PSV)] of foetal middle cerebral artery and gestational age in normal pregnancies of 20 to 40 weeks. It was observed that RI, PI and S/D were decreased with the advance of gestational age but PSV was increases with the advance of gestational age. Statistical analyses showed there were significant difference between mean PSV, RI and PI before and after 25 weeks of gestation. No significant difference was found between mean S/D before and after 25 weeks of gestation. It was observed from Correlation analysis between Doppler indices with independent gestational age that all the Doppler indices of foetal middle cerebra artery was positively correlated with the whole gestation period. The statistical analysis showed only PSV and RI were significantly correlated with the gestational age. Simple regression analysis between dependent Doppler index with independent gestational age before and after 25 weeks revealed that all the Doppler indices had positive relationship with the corresponding gestational age but relationship between PSV and PI (before 25 weeks) with their corresponding gestational ages were only statistically significant.DOI: http://dx.doi.org/10.3329/birdem.v2i2.12306 Birdem Med J 2012; 2(2) 77-80

Objective: The objective of this study was to determine the hemodynamic changes in the umbilical artery (UA) and middle cerebral artery (MCA) with oligohydramnios, during third trimester of pregnancy. Materials and Methods: A cross-sectional descriptive study was done in a perinatal ultrasound center, over a 9-month period. The participant sample size was 64, and all of the women were conveniently consented and selected for the study. All individuals were referred for obstetrical sonography in the third trimester, with oligohydramnios. All fetal anomalies, such as a neural tube defect, dwarfism, an abdominal wall defect, were excluded from the study. Results: The mean systolic to diastolic (S/D) ratio for the UA was 3.01, within a range of 1.49 to 5.60 (± 0.79 SD). The mean pulsatility index (PI), of the UA, was 1.11, within a range of 0.41 to 5.51 cm (± 0.64 SD). The mean resistive index (RI) of the UA was 0.66, within a range of 0.33 to 1.25 cm (± 0.13 SD). The mean S/D ratio of the MCA was 5.68, within a range of 2.05 to 26.10 (± 3.10 SD). The mean PI of the MCA was 1.67 within a range of 0.75 to 2.55 cm (± 0.45 SD). The mean resistive index (RI), of the UA, was 0.82 within a range of 0.51 to 1.77 cm (± 0.82 SD). Conclusion: The Doppler indices may rise as pregnancy advances, especially in fetuses with oligohydramnios. In these types of patients, the flow within the MCA may decrease, with an increase in the gestational age. Consequently, it appears that oligohydramnios may lead to vascular remodeling of the UA and MCA.

Abstract Objective This study aimed to evaluate the effect of vaginal progesterone (P) administration during the second and third trimesters of pregnancy on Doppler velocimetry of uterine, umbilical, and middle cerebral vessels. Study Design A prospective cohort study conducted on 80 women at risk for preterm labor. Uterine artery, umbilical artery, and middle cerebral artery (MCA) Doppler indices were measured before and after 1 week of administration of 200 mg twice daily vaginal P. The primary outcome parameter was the change of MCA pulsatility index (PI) after P administration. Secondary outcomes included changes in uterine artery and umbilical artery Doppler measurement. Results There was no significant changes of umbilical artery resistance index (RI) (0.69 ± 0.049 vs. 0.68 ± 0.041), umbilical artery PI (1.14 ± 0.118 vs. 1.11 ± 0.116), uterine artery RI (0.66 ± 0.12 vs. 0.66 ± 0.107), uterine artery PI (1.00 ± 0.26 vs. 1.016 ± 0.24), and MCA PI (1.27 ± 0.18 vs. 1.26 ± 0.23) measurements before and after 1 week of P administration, respectively. Conclusion Administration of vaginal P has no significant effects on uterine artery, umbilical artery, and MCA Doppler indices.
