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»
