The readmission of a parturient with natural delivery after discharge due to residual fetal membrane: A case report.

RATIONALE: Placental residue is a relatively common and sophisticated disease among obstetric delivery complications. A failure to detect placental residue in time may cause poor outcomes such as postpartum hemorrhage and puerperal infection.

PATIENT CONCERNS: We present the case of a 33-year-old full-term singleton parturient with placental residue. Upon precipitate labor and childbirth, the placenta and fetal membranes were examined to be intact. However, 1 day after discharge, she felt that there was discharge from the vagina and thus presented to our emergency department.

DIAGNOSES: The patient was diagnosed with residual membranes and readmitted to the hospital for uterine curettage.

INTERVENTION: Uterine curettage was performed under B-ultrasound guidance.

OUTCOME: The patient was discharged smoothly without any postoperative complications.

LESSONS: This paper can provide significant enlightenment for the prevention and early treatment of placental residue, including enhancing the risk awareness of high-risk patients, standardizing the process of clinical examination of the placenta, and early uterine contraction promotion to assist in the discharge of residual tissue, so as to reduce the occurrence of placental residue.
