                                 Objective: We evaluated the diagnostic accuracy of a new  ultrasound sign, “intracervical lakes”, in predicting presence and outcome of  placenta accreta spectrum (PAS).
Methods: An observational study was done on 110 women  with placenta previa or low-lying placenta at 36 weeks’ gestation, referred to  Ain Shams Maternity Hospital between January 2021and December 2021, with all  examined by ultrasound to confirm placental location, presence/absence/degree  of invasion, and intracervical lakes sign. All underwent caesarean section and  final diagnosis of PAS was made intraoperatively. Specimen was histologically  examined.
Results: US findings predicted PAS with sensitivity 76.8  % and specificity 85.2 %, while PAS sign+ intracervical lakes increased  specificity to 98.1 %, positive predictive value 9.. Read More»
