Hereditary thrombophilia and recurrence of ischemic placental disease

OBJECTIVE: We sought to evaluate whether testing for hereditary thrombophilia alone or in combination with second-trimester uterine artery Doppler (UAD) is useful in predicting recurrent complications in patients with previous preeclampsia, placental abruption, or stillbirth. STUDY DESIGN: Between 2001 and 2005, 110 consecutive women were included in the study and received 100 mg of aspirin daily. Adjustment was made for several maternal confounding factors using a logistic regression model. RESULTS: After multivariable logistic regression analyses, only abnormal UAD assessment was significantly associated with recurrent complications (odds ratio, 11.2; 95% confidence interval, 3.8-32.6) Combining the results of UAD and the presence of laboratory markers of thrombophilia failed to improve the accuracy of UAD to predict recurrent complications. CONCLUSION: Hereditary thrombophilia testing is not useful in predicting recurrent complications in subsequent pregnancy.
