ROLE OF ULTRASOUND IN PREDICTION OF PREGNANCY OUT COME IN THREATENED ABORTION

Background: Threatened miscarriage constitutes 15–20% of pregnancies and is one of the commonest gynecological emergencies. Previously, the volume of an intrauterine hematoma (IUH) or on the presence of vaginal bleeding was considered but not the location of the hemorrhage. Objective: To predicted pregnancy outcome through sonographic finding in women presenting with symptoms of threatened abortion. Subjects and methods: This was a prospective study held on 300 patients who attended the out-patient clinic or the causality department of Obstetrics &Gynecology, in Tahta general hospital. Patients were with clinical diagnosis of threatened abortion in their 1st trimester of pregnancy, attended to outpatient clinic or causality department, giving a history of bloody vaginal discharge or vaginal bleeding. Results: there were statistically significant difference of mean values of sub trophoblastic arteries RI for the continued group and aborted group in all gestational age. There were statistically significant difference of mean values of sub trophoblastic arteries PI for the continued group and aborted group in all gestational age. Conclusion: CRL and FHR are good sonographic indicators for the prediction of outcome in women with threatened miscarriage. Color Doppler of subtrophoblastic arteries is useful in prediction of pregnancy outcome in threatened abortion .The incidence of maternal and fetal complications increased in cases with threatened miscarriage that completed the pregnancy.
