Lance White; ShaleceKofford, RN, MPH; Janalee Allred, RN; InekePostma; Michael Varner, MD OBJECTIVE: To determine if decreased resistance (vasodilatation) in the Maternal Middle Cerebral Artery (MMCA)in the second trimester can predict third trimester development of preeclampsia. STUDY DESIGN: 405 low risk gravidas had MMCA Transcranial Doppler (TCD) once in the second trimester. Maternal/neonatal outcomes were evaluated after delivery. Mean BP, MMCA velocities, Resistance Index (RI), Pulsatility Index (PI), and Cerebral Perfusion Pressure (CPP) were compared between normotensive and preeclamptic cohorts. RESULTS: Seven subjects (1.7%) developed preeclampsia. An RI <0.54 and PI <0.81 were clinically useful in predicting subsequent preeclampsia.Areas under the ROC curves for RI and PI were 0.93 and 0.93 respectively with optimal sensitivity and specificity of 86% and 93%. Positive and Negative Likelihood Ratios were 11.8/0.15 (RI), 12.3/0.15 (PI). CONCLUSIONS: TCD indices of low MMCA resistance in the second trimester are predictive of the subsequent development of preeclampsia in a low risk, ethnically homogenous population.
