A prospective study was carried out using 100 patients with 64 appropriately matched controls, to follow the course of low-lying placentae, diagnosed before 20 wk gestation. 94% of these placentae had moved out of the lower segment by the 32nd wk, while only 2% of the total required a caesarean section for placenta praevia. No evidence of intrauterine growth retardation or increased incidence of preeclampsia was found. In the light of this and other studies, a routine ultrasound re-check of placental position subsequent to 32 wk is deemed unnecessary unless clinically indicated, saving unnecessary maternal anxiety and over-exposure to ultrasound. Since the posterior low-lying placentae are those more likely to remain praevia, it is they that require follow-up scans.
