What is the most severe outcome of placental adhesion to the uterus?

There is no specific term for "the most severe outcome of placental adhesion to the uterus," but placental adhesion can lead to serious complications such as postpartum hemorrhage, poor uterine contraction, increased risk of infection, organization of residual tissue, and secondary infertility, all of which significantly threaten maternal health. If persistent bleeding, abdominal pain, fever, or similar symptoms occur after delivery, prompt medical attention is recommended.

1. Postpartum Hemorrhage: Adhesion prevents complete detachment of the placenta, leaving open blood vessels on the uterine surface that fail to close effectively, potentially causing rapid, massive bleeding. Severe cases may lead to shock and even be life-threatening.

2. Poor Uterine Contraction: Adhesions interfere with the normal contraction of uterine smooth muscle, resulting in uterine atony. This not only exacerbates bleeding but may also prolong lochia discharge and delay overall uterine recovery.

3. Increased Risk of Infection: Retained placental tissue creates a favorable environment for bacterial growth, increasing the likelihood of gynecological infections such as endometritis and pelvic inflammatory disease, which may present with symptoms like fever, abdominal pain, and foul-smelling lochia.

4. Organization of Residual Tissue: Placental tissue that remains unexpelled in the uterine cavity for prolonged periods may gradually become organized and firmly adhered to the uterine wall, potentially leading to intrauterine adhesions, menstrual abnormalities, and other long-term complications.

5. Secondary Infertility: Sequelae such as intrauterine adhesions and endometrial damage can impair embryo implantation, reducing the chances of future pregnancy. Some patients may experience recurrent miscarriage or infertility.

After childbirth, follow medical advice to monitor vaginal bleeding and lochia. Maintain external genital hygiene, avoid sexual intercourse too early, engage in moderate ambulation to promote uterine contraction, and consume a diet rich in high-quality protein and iron to support recovery.
