ROLE OF COLOR DOPPLER SONOGRAPHY IN PRE NATAL ASSESSMENT FOR PREGNANCY OUTCOME- A RETROSPECTIVE OBSERVATIONAL STUDY
Abstract
Background: High-risk pregnancies are associated with many adverse perinatal outcomes. Doppler ultrasonography has proven to be an invaluable obstetric tool for over 30 years.
Objective: The aim of this study is to evaluate the role of color Doppler in prenatal assessment of normal as well as high-risk pregnancies.
Materials and Methods: This was a retrospective observational study carried out on 216 pregnant women for one year in the Department of Radiology with the help of the Department of Obstetrics and Gynecology. Antenatal women in the age group of 20-40 years with singleton pregnancy of gestational age of 26 weeks to term were involved in the study. The study model considered normal variations as well as some fetal abnormalities. Doppler study of umbilical artery, fetal middle cerebral artery (MCA), and both the maternal uterine arteries was done. Details of obstetric history and delivery were taken. Patients were followed up at regular intervals.
Results: A total of 216 women having 26 week to term pregnant for single fetus were assessed by the color Doppler scan. High-risk pregnancy was more common in the age group of 31 years and more. The most common high-risk factor in pregnancy was pregnancy induced hypertension. Out of 216 Doppler scans 75 fetuses were found to be having anomalies. In which 60 fetuses survived and 15 fetus were dead till the term. Intrauterine growth retardation and Diastolic notch in uterine artery showed high prevalence i.e. 8 (10.66%) in prenatal color Doppler scan. Cardiac dysrhythmia found to be least prevalent i.e. 3(4%) in all anomaly scans.
Conclusion: Doppler can be used as a reliable tool for demonstrating prenatal fetal anomalies prenatal assessment of high-risk pregnancy. It provides useful guidance and early intervention to improve fetal outcome.
