EFFICACY OF COLOR DOPPLER SONOGRAPHY IN PRE NATAL ASSESSMENT FOR LOW AND HIGH RISK PREGNANCY OUTCOME

Abstract

Background: Numerous unfavourable perinatal outcomes are linked to high-risk pregnancies. For more than 30 years, Doppler ultrasonography has shown to be a useful obstetric tool. 

Aim: This research seeks to determine how colour Doppler works in the prenatal diagnosis of both low-risk and highrisk pregnancies.

Methods: This was a one-year retrospective observational research conducted at the Department of Radiology, in collaboration with the Department of Obstetrics and Gynaecology, on 216 pregnant women. The research included pregnant women aged 20 to 40 who were carrying a singleton pregnancy with a gestational age of 26 weeks to term. Both typical variances and some foetal anomalies were taken into account in the study model. The foetal middle cerebral artery (MCA), the umbilical artery, and both mother uterine arteries underwent Doppler imaging. Information about the delivery and obstetric history was recorded. Patients were checked on a frequent basis. 

Results: The colour Doppler scan was used to evaluate 216 pregnant women who were 26 weeks along with a single foetus. Pregnancies at high risk were more prevalent among women aged 31 and older. The most prevalent high-risk factor during pregnancy was hypertension brought on by pregnancy. Anomalies were discovered in 75 foetuses out of 216 Doppler scans. Whereby 15 foetuses died before term and 60 foetuses survived. In a prenatal colour Doppler scan, 8 (10.66%) cases of intrauterine growth retardation and a diastolic notch in the uterine artery were shown to be highly prevalent. 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.
