Biochemical Versus Ultrasound Findings as Predictors of Fetal Loss in Cases of First Trimester Threatened Miscarriage

Threatened miscarriage occurs in about one-fifth of pregnancies with an estimated miscarriage rate of 3-16% after successful demonstration of fetal cardiac activity. Various biochemical markers have been studied previously to predict the outcome of threatened miscarriage; However, the results have been conflicting. Several studies have documented that a slow embryonic heart rate at 6.0-7.0 Weeks' gestation is associated with a high rate of first trimester fetal demise. our aim: To evaluate the accuracy of ultrasound findings in comparison to serum CA125 and progesterone in predicting fetal demise in cases of first trimester threatened miscarriage. Will this pregnancy be continued after the first trimester or not?
