DOPPLER ULTRASOUND IN HIGH RISK PREGNANCY WITH ITS PERINATAL OUTCOME: A HOSPITAL BASED PROSPECTIVE STUDY.

Dr. Richa Choudhary, Dr. Rishikant Sinha

Abstract


OBJECTIVES: This study was to evaluate the diagnostic value of various abnormal waveform of Doppler ultrasound of triple vessels (uterine
artery, middle cerebral 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 cerebral 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 cerebral 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.
