Prediction of intrauterine fetal demise by feto-maternal Doppler at the 20 – 24th week of gestation

Purpose: Intrauterine fetal demise (IUFD) could be a consequence of placental insufficiency. Usually impedance to flow in the uterine arteries decreases with gestation due to trophoblastic invasion of the spiral arteries that are converted into low-resistance. This process refers to first and second trimester of pregnancy. Several Doppler screening studies in the second trimester of pregnancy have demonstrated an association between increased impedance to flow in the uterine arteries and subsequent development of pregnancy complications. The aim of this study was to assess correlation between feto-maternal Doppl…
