Clinical Causes: Adherent placenta, such as placenta accreta, where the placenta attaches too deeply into the uterine wall. Trapped placenta, which occurs when the placenta detaches but becomes physically trapped within the uterine cavity. Previous cesarean sections or uterine surgeries that alter placental attachment or removal. Abnormal placental development during pregnancy. Uterine anomalies or abnormalities that impair placental separation.

Key Symptoms: Incomplete expulsion of the placenta after childbirth. Persistent uterine contractions or discomfort. Possible signs of infection, such as fever or foul-smelling discharge (though not directly caused by hemorrhage). Lower abdominal or pelvic pressure or heaviness. Delayed postpartum bleeding or retention symptoms even without active bleeding.

Diagnosis Path: Physical examination to assess uterine firmness and size. Ultrasound imaging to visualize retained placental tissue within the uterus. Further imaging, such as MRI, in complex cases to evaluate placental attachment and location. Assessment of symptoms and medical history to rule out other postpartum conditions.

Treatment Protocols: Manual removal of the placenta by a trained healthcare professional, often under ultrasound guidance. Medication administration, such as oxytocin, to facilitate uterine contractions and expulsion. Dilation and curettage (D&C), a minor surgical procedure to remove retained tissue if manual methods are unsuccessful or not feasible. Monitoring for signs of infection or other postpartum complications. Use of antibiotics if an infection develops post-removal. In rare cases, surgical intervention such as hysterectomy may be necessary if other methods fail or complications arise.
