Abstract

Introduction: Doppler ultrasound would be a useful in antenatal fetal well-being and timely intervention. On the basis of abnormal Doppler results, obstetrical decision makingmay improve and prevent intrauterine death because hypoxic cerebral damage may begin before labor and intrapartum asphyxia is probably more damaging when superimposed on underlying hypoxia. Aims: To evaluate the role of Foetal Doppler in high risk pregnancy with relation to perinatal outcome. Materials and methods: A total of 50 patients over a period of 16 month were screened with Doppler scans at late second and third trimester. The patients with high-risk pregnancies were volunteers recruited from women undergoing routine ultrasound examination in the late second and third trimesters. Results: intrauterine growth restriction (IUGR) (n=39); preeclampsia; preeclampsia with IUGR, obesity; and others. Most of the patients were primigravida and constituted 62% of total in each group. MCA PSV increased and PI decreased with advanced gestational age. The mean PI ratios were 0.75 ± 0.15 respectively. The values in high risk group were statistically significantly reduced from the mean in values in normal pregnancy. Of 50 patients 39 (78%) had normal flow, 4 (85) had pulsation and 7 (14%) had reversal of flow. Reversal of flow was significantly related to fetal morbidity and mortality. PV IV of Ductus Venosus in high risk group was (0.78 ± 0.54). The values were statistically significant increased as compared to pregnant women with no high risk factors. None of the patients had reversal of “A” wave. For adverse fetal outcome abnormality, fetal venous parameters were more sensitive and specific as compared to the arterial parameters. Conclusion: Fetal Doppler velocimetry studies of the foetal circulation play a crucial role in the monitoring of high risk pregnancies and henceforth, help to evaluate the optional time for delivery
