Trial Summary
What is the purpose of this trial?
This trial will compare a new treatment method where the placenta is left in the uterus to the standard practice of removing the uterus for patients with a severe pregnancy condition called placenta accreta spectrum. The goal is to see if this new method is safer and less costly.
Do I need to stop my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What data supports the effectiveness of the treatment Cesarean hysterectomy for placenta accreta spectrum (PAS)?
Is cesarean hysterectomy for placenta accreta spectrum (PAS) generally safe for humans?
Cesarean hysterectomy for placenta accreta spectrum (PAS) can be safe when performed by experienced teams, as careful surgical techniques and multidisciplinary care can reduce risks like significant bleeding. However, it is a complex procedure with potential for serious complications, so it requires careful planning and expertise.12356
How does the treatment for placenta accreta spectrum differ from other treatments?
The treatment for placenta accreta spectrum (PAS) can involve either a cesarean hysterectomy, which removes the uterus, or conservative management, which aims to preserve the uterus by leaving the placenta in place to be reabsorbed naturally. This conservative approach can help maintain fertility, unlike the more common cesarean hysterectomy.23478

Eligibility Criteria
This trial is for pregnant individuals over 18 with a history of cesarean delivery and placenta previa or an anterior low-lying placenta who are suspected of having Placenta Accreta Spectrum (PAS) based on prenatal scans. They should be planning to deliver between weeks 34 and 36. Those typically recommended for hysterectomy due to PAS can join, but not those with fetal demise, low suspicion for PAS, planned delivery before week 24, hospitalized due to bleeding, or carrying multiples.Inclusion Criteria
I have been advised to undergo a hysterectomy.
Planned delivery between 34w0d and 36w0d gestation
You have had a previous C-section and currently have a condition called placenta previa or a low-lying placenta, which is suspected to be a condition called placenta accreta spectrum based on imaging tests like ultrasound or MRI.

Interventions
- Cesarean hysterectomy for placenta accreta spectrum (PAS) (Procedure)
- Conservative management for placenta accreta spectrum (PAS) (Procedure)
Trial OverviewThe study compares conservative in situ management versus the standard Cesarean hysterectomy in treating Placenta Accreta Spectrum (PAS). It aims to determine if conservative treatment is a safer option that could replace hysterectomy while also gathering data to help patients make informed decisions about their care.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: Conservative Management for Placenta Accreta Spectrum (PAS)Experimental Treatment1 Intervention
Subjects who are randomized to to conservative management will undergo a cesarean delivery followed by a period of close observation in the operating room for 30-45 minutes to be sure there is no excessive bleeding or risk to keep the placenta inside
Group II: Hysterectomy at time of delivery for Placenta Accreta Spectrum (PAS)Active Control1 Intervention
Subjects who are randomized to cesarean hysterectomy will undergo a cesarean delivery followed immediately by hysterectomy to remove the placenta and uterus together

Effect of anesthesia selection on neonatal outcomes in cesarean hysterectomies for placenta accreta spectrum (PAS).Munoz, JL., Hernandez, B., Curbelo, J., et al.[2022]
In a study of 11 patients with placenta accreta spectrum (PAS) managed by leaving the placenta in situ, 55% successfully preserved their uterus, suggesting this approach may be a viable option for selected patients.
Among those who preserved their uterus, 67% went on to have subsequent pregnancies, indicating that this management strategy could allow for fertility preservation while managing PAS effectively.

Conservative management or cesarean hysterectomy for placenta accreta spectrum: the PACCRETA prospective study.Sentilhes, L., Seco, A., Azria, E., et al.[2022]
Surgical management of placenta accreta spectrum (PAS) is complex and requires careful planning and expertise to ensure safety during procedures.
A multidisciplinary approach to managing PAS can significantly reduce complications and improve outcomes, particularly by minimizing the risk of severe hemorrhage during surgery.

Surgical Techniques for the Management of Placenta Accreta Spectrum.Khoury-Collado, F., Newton, JM., Brook, OR., et al.[2023]
In a study of 122 pregnancies complicated by Placenta Accreta Spectrum (PAS), cesarean hysterectomies performed by gynecologic oncologists showed similar maternal morbidity outcomes compared to those performed by Ob/Gyn specialists, indicating that both specialties can effectively manage these complex cases.
However, gynecologic oncologists were associated with lower rates of intraoperative acidosis and shorter post-operative stays, suggesting they may provide enhanced surgical management in more complicated PAS cases, particularly those involving placenta percreta.

In a study of 442 women with placenta accreta spectrum (PAS), the most common management approach was cesarean hysterectomy, with no maternal deaths reported, indicating a high level of safety in these referral centers.
The study found that prenatal diagnosis of PAS was strongly correlated with the clinical severity of the condition, and there was a significant reduction in mean blood loss over time, suggesting improved management techniques and outcomes.

A modified uterine preserving surgical technique for managing placenta accreta spectrum (PAS) was successfully implemented in 20 patients, preserving the uterus in 90% of cases, which is a significant advantage over traditional Caesarean hysterectomy.
The procedure demonstrated a mean blood loss of 1305 CC and a mean operative time of 123 minutes, with minimal complications, indicating it is a safe option for conservative management of PAS, especially in resource-limited settings.
