What is a retroplacental hematoma?

This type of hemorrhage occurs behind the placenta. The hematoma, therefore, separates the placenta from the uterine wall. The source of bleeding is probably from spiral arteries. Sonographically, a retroplacental hematoma may mimic a thickened placenta because the hematoma is commonly isoechoic to the placenta.

Can a retroplacental hematoma mimic a thickened placenta?

Sonographically, a retroplacental hematoma may mimic a thickened placenta because the hematoma is commonly isoechoic to the placenta. It should be suspected if the retroplacental hypoechoic zone is thickened to >2 cm 6 . Otherwise, the retroplacental hematoma may be hypoechoic or may be of heterogeneous echogenicity.

What are the different types of abruption of the placenta?

Premature separation of the placenta from the uterine wall by maternal blood; strongly associated with maternal hypertensive disorders of pregnancy and maternal vascular malperfusion of the placenta 3 main categories: classic acute abruption, acute marginal abruption and chronic abruption

Are there biomarkers for placental abruption?

Although several biomarkers have been evaluated, none has so far turned out to be useful. Placental abruption is defined as the complete or partial premature separation of the placenta before delivery with hemorrhage into the decidua basalis.
