To explore the strength of association between different maternal and pregnancy characteristics and the occurrence of abnormally invasive placenta (AIP). Pubmed, Embase, CINAHL databases were searched. The risk factors for AIP explored were: obesity, age >35 years, smoking before or during pregnancy, placenta previa, prior cesarean section (CS), placenta previa and prior CS, prior uterine surgery, abortion and uterine curettage, fertilization (IVF) pregnancy and interval between a previous CS, and a subsequent pregnancy.

- * A total of 210 women participated, and ultrasound demonstrated a sensitivity of 100% when at least one sign was present, though specificity was lower at 61.9%. Using multiple signs increased specificity without affecting sensitivity.
- * The findings suggest that ultrasound is highly accurate in diagnosing the depth of placental invasion, especially in women with certain risk factors, enhancing the potential for better clinical management.
Objective: To ascertain whether the prevalence of ultrasonography signs of abnormally invasive placenta (AIP) changes during pregnancy.
Methods: The present retrospective analysis included women with a prenatal diagnosis of AIP that was confirmed at delivery between January 1, 2007, and April 30, 2017, at the Department of Obstetrics and Gynaecology, Arnas Civico Hospital, Palermo, Italy. Ultrasonography signs of AIP were recorded at four different intervals during pregnancy: early first (6-9 weeks), first (11-14 weeks), second (15-24 weeks), and third trimester (25-36 weeks).
Article Synopsis
- - The study aimed to assess how accurately ultrasound can detect the severity of abnormally invasive placentation (AIP) by analyzing various ultrasound signs related to placental invasion.
- - A review of 20 studies involving 3209 pregnancies found that ultrasound demonstrated good diagnostic accuracy, with high sensitivity and specificity for different types of placentation (accreta, increta, percreta).
- - Key ultrasound signs like placental lacunae and the loss of a hypoechoic zone were shown to be valuable indicators, with varying sensitivities and specificities in identifying the extent of placental invasion.
