Doppler Ultrasound in High Risk Pregnancy with its Perinatal outcome: A Hospital Based Prospective Study.

Abstract :

Objectives: This study was to evaluate the diagnostic value of various abnormal waveform of Doppler ultrasound of triple vessels (uterine artery, middle cereal artery and umbilical artery) in high–risk pregnancies with its perinatal outcome. Methods: Doppler ultrasonography was performed to all cases of high risk pregnancy in every week. And d2ianostic value of waveforms were obtained for umbilical artery, uterine artery and middle cereal artery. And various indices were calculated viz. Pulsatility Index (PI) (difference between peak systolic and diastolic flow over the mean flow velocities). Resistance Index (RI), (difference between peak systolic and diastolic flow over systolic flow and S/D ratio done). Flow velocimetry waveform of uterine artery, umbilical and middle cereal artery were obtained. Neonatal follow up was obtained. Results: Data was analyzed by using simple statistical methods with the help of MS–office software. All the data were tabulated and percentages were calculated. Conclusions: Maternal age 20–25 years had commonly associated with high risk pregnancy with spontaneous vaginal delivery. Most of the cases had second gravida and adverse MCA/UA pulsatility index. Abnormal Doppler was found in all the cases of PIH with IUGR. Most of the cases of high risk pregnancy had UmbA S/D >3, abnormal C/U PI and low birth weight babies. And highest sensitivity and specificity of pulsatility index to predict perinatal outcome were seen in MCA/UmbA PI and MCA PI respectively. Hence Doppler ultrasonography is one of the best investigating modalities to predict high risk pregnancy and perinatal and neonatal management.
