​Pathology - Placental Attachment Abnormalities (Abruptio Placentae, Placenta Previa, Placenta Accreta)
Abruptio placentae can be linked to disseminated intravascular coagulation (DIC) and has a higher risk when combined with smoking, cocaine use, and hypertension.

Placenta accreta is more likely to occur in individuals with previous C-section scars or endometrial irritation.
Placenta previa is more likely to occur in individuals with previous C-section scars.

Abruptio placentae refers to the premature detachment of the placenta.
Placenta accreta occurs when a faulty decidual layer enables the placenta to connect directly to the myometrium.
Placenta previa is when the placenta attaches to the lower part of the uterus or cervix, potentially blocking the cervical opening, and it can occur alongside placenta accreta.

Abruptio placentae is characterized by painful uterine bleeding typically occurring in the third trimester and may lead to fetal death.


Placenta accreta leads to significant bleeding following childbirth.

Placenta previa is characterized by painless bleeding during any trimester and can lead to premature childbirth.

Abruptio placentae requires immediate delivery of the fetus and management of maternal hemorrhage.
Hysterectomy may be required to halt bleeding in cases with placenta accreta.

Placenta previa may need bed rest and potential hospitalization.
