Lateral placentation and adverse perinatal outcomes
2020, PlacentaCitation Excerpt :It is reasonable to assume that site of implantation affects placental perfusion [4,5], with lateral placentas receiving supply mostly from the ipsilateral uterine artery [6]. Abnormal placental perfusion may predispose to preterm birth (PTB), SGA, hypertensive disorders of pregnancy and fetal distress [5–8]. Previous studies suggest that lateral placentation may have a negative impact on fetal growth and length of gestation [3,9,10], but results are conflicting.

2018, American Journal of Obstetrics and GynecologyCitation Excerpt :Ultrasound imaging, and in particular color Doppler imaging, has allowed the study of both the umbilicoplacental and uteroplacental circulations from the first trimester of gestation onward.6,7 These techniques have been used extensively in the screening of placental-related complications of pregnancy, such as preeclampsia,8,9 and the management of a fetus presenting with primary or secondary FGR.10 More recently, 3-dimensional Doppler imaging11,12 and magnetic resonance imaging (MRI)13 have been used to study the development of the placental and fetal circulations, but their use in clinical practice remains limited.

2008, PlacentaCitation Excerpt :If, however, the placenta is not preferably implanted on one side, both uterine arteries have similar indices [65]. Several criteria define abnormal waveform: (1) elevated Doppler indices; (2) presence of a diastolic notch after 17 weeks; (3) a lack of difference in indices obtained from the uterine arteries on the placental and non-placental sides [66,67]. Fig. 7c demonstrates a very abnormal waveform in the uterine artery with elevated Doppler indices (low diastolic velocity) and presence of a diastolic notch, both of these indicating increased impedance in the uterine circulation.
