Background: Pregnant women with previous history of recurrent miscarriage have higher risks of adverse pregnancy outcomes. Management of current pregnancies in patients with recurrent miscarriage is distressing for the patient and frustrating for the health care provider, especially where treatment options are limited. Doppler velocimetry studies of pregnant women in second trimester with recurrent miscarriage can predict adverse pregnancy outcomes. In this paper, we predict pregnancy outcomes using Doppler velocimetry among women with recurrent miscarriage. Patients and Methods: It was a prospective study among pregnant women with history of recurrent miscarriage. The umbilical artery Doppler velocimetry was carried out in second trimester using 3.5 mHz convex of the Mindry Digital Ultrasound Imaging System (Model DP-8800Plus; Shenzen Mindray Biomed electronics, China). Results: A total of 67 pregnant women with history of recurrent miscarriage were recruited for the study. The mean age ± standard deviation was 28.94 ± 5.59. Thirty-nine (58.21%) had abnormal resistive indices of which 15 (22.39%) had diastolic notches. Others had normal resistive indices. There were significant associations between high resistive index (RI) and the occurrence of preterm birth, low Apgar scores, low birth weight, and intra uterine fetal death. Conclusion: Majority of high risk pregnant women with history of recurrent miscarriage have high umbilical artery RI in second trimester of gestation. RI of at least 0.715 of the umbilical artery Doppler velocimetry is associated with adverse pregnancy outcomes following receiver operating characteristic analysis. Abnormal umbilical artery Doppler velocimetry among pregnant women with recurrent miscarriages predicted adverse neonatal outcomes.
