The term placenta accreta is a general term for an abnormal placental attachment disorder.

In placenta increta, the placenta invades all the way to the surface of the uterus.

What best describes this image?

The pathology of placenta accreta is related to a defect in the decidua basalis caused by uterine scaring.

Other than C-sections, no other forms of uterine scarring are associated with placenta accreta.

What best describes this image?

In placenta increta, microscopic examination of the uterine specimen shows invasion of the chorionic villi (placental tissue) into the myometrium.

The incidence of placenta accreta has not changed during the last several decades.

Given the presence of this image, what would be your next recommendation?

The number of C-Sections has no bearing on the incidence of placenta accreta.

The presence or absence of lacunae is important in assessing the risk for maternal hemorrhage. In some studies, no hysterectomies were performed when lacunae were absent.

Given this image, what is the next imaging modality you would recommend?

The risk of placenta previa is higher in pregnancies following assisted reproduction.

The rate of placenta previa is about the same among twin pregnancies compared to singleton pregnancies.

This image most likely represents what clinical entity?

If a total placenta previa is present at 30 weeks gestation, about 75% will persist or be present at term.

Placenta previa patients have higher rates of:

In an incomplete placenta previa, the placental edge is within which distance from the internal cervical os.
