Outcome Measures

Primary Outcomes (3)

  • Assessment of risk factors affecting peripartum hysterectomy in placenta previa patients undergoing without MRI screening

    Binary measure indicating whether peripartum hysterectomy occurred (yes/no).

    Assessed during the peripartum period, within the first two days postpartum.

  • Clinical risk factors affecting p-TAH in patients with t-PP undergoing p-MRI.

    Binary measure indicating whether peripartum hysterectomy occurred (yes/no).

    Assessed during the peripartum period, within the first 2 days postpartum.

  • Identification of risk factors affecting neonatal mortality regardless of whether MRI scanning is used.

    Binary measure indicating whether neonatal mortality occurred (yes/no).

    Assessed at the time of delivery.

Secondary Outcomes (2)

  • The ROC analysis of the placental volume (S1 and S2 sectors), CCL, and CCD obtained from the p-MRI scan for indications of peripartum hysterectomy

    Assessed based on ROC analysis.

  • Peripartum Hysterectomy Occurrence

    Assessed during the peripartum period, within the first 2 days postpartum.

Study Arms (2)

Total placenta previa (t-PP) patients who underwent placental MRI (p-MRI).

ACTIVE COMPARATOR

The study compares clinical factors and p-MRI findings between two surgical procedures: Caesarean Section (C/S) and Peripartum Total Abdominal Hysterectomy (p-TAH). The study analyzes both univariate and multivariate associations with surgical procedures. This arm presents the results of a study assessing risk factors affecting peripartum hysterectomy in placenta previa patients, focusing on the impact of MRI screening. Peripartum hysterectomy (p-TAH) refers to the surgical removal of the uterus around the time of childbirth. The arm does not explicitly mention specific interventions to be administered. However, it provides information on clinical and p-MRI factors that might influence the surgical procedure (C/S or p-TAH) choice in placenta previa patients. The interventions, if any, would likely be based on assessing these risk factors and involve decisions on the type of surgery, additional procedures, or use of certain medical interventions based on the patient's condition.

Interventions

Peripartum total abdominal hysterectomy (cesarean hysterectomy) refers to a surgical procedure in which a woman undergoes both a cesarean section (C-section) and a hysterectomy simultaneously. Placenta Accreta, Increta, or Percreta: These are conditions where the placenta attaches too deeply to the uterine wall. In cases of severe attachment, it may be difficult to remove the placenta without causing excessive bleeding, and a hysterectomy may be required. Cesarean hysterectomy is a major surgical procedure involving significant medical expertise and coordination among healthcare professionals, including obstetricians and surgeons. The decision to perform a cesarean hysterectomy is usually made in emergency situations to address life-threatening complications.

A cesarean section (C/S) involves making an incision in the abdominal wall and uterus to deliver a baby when a vaginal delivery is not feasible or safe. Total placenta previa refers to a condition where the placenta completely covers the opening of the cervix in the uterus. This condition can pose significant risks during pregnancy and childbirth, and it often necessitates a planned cesarean section (C/S) for delivery.

Also known as: C-section

Neonatal mortality refers to the death of a newborn within the first 28 days of life. This period is divided into early neonatal mortality, which covers the first seven days of life, and late neonatal mortality, which extends from the eighth to the 28th day. Neonatal mortality is a critical measure of the health and well-being of infants and is often used to assess a population's overall health and healthcare systems. To reduce neonatal mortality, efforts are made to improve maternal healthcare, access to prenatal care, skilled attendance during childbirth, and the availability of neonatal healthcare services. Tracking and addressing factors contributing to neonatal mortality are crucial for improving the chances of survival of newborns and overall health outcomes.

Model Details: 277 singleton pregnancies that met the inclusion criteria and were diagnosed with total placenta previa (t-PP) in the third trimester were divided into two groups according to whether a placental-MRI (p-MRI) was performed. Nevertheless, we explored whether pregnant women diagnosed with total placenta previa (t-PP), with or without a placental-MRI (p-MRI), needed to undergo peripartum-total abdominal hysterectomy (p-TAH) during cesarean section (C/S) due to the placenta accreta spectrum (PAS).
