About this study
Official title: Evaluation of Clinical Outcomes and Acceptability of an Anatomical Classification for Placenta Accreta Spectrum, a Multicentric Prospective Cohort Study
The present study is a prospective multicenter study consisting of a cohort of patients with prenatal or intraoperative diagnosis of PAS, evaluating the clinical outcomes of the group of patients found in each category of the topographic classification. In addition, an approach to evaluate the acceptability of this classification among the obstetrician-gynecologists of the participating medical centers will be included.
Read the detailed description
The aim of this study is to describe the demographic and clinical characteristics of patients with a diagnosis of placenta accreta spectrum, and to determine the correlation between the topographic classification and the clinical outcomes found in the study. Finally, to evaluated whether the proposed classification is accepted by the obstetrician-gynecologists of the participating centers that manage placenta accreta spectrum patients.
It is an observational, multicentric study of a prospective cohort, in which data will be obtained from the medical records and other documents in each participating center, which are considered to be of routine use in day-to-day clinical practice. The study of the outcomes proposed in this protocol will be limited to those recorded in the clinical records and will be taken into account until the participant is discharged from the hospital, during which a surgical intervention was performed due to the suspicion or diagnosis of PAS.
It is projected that the period of patient enrollment will last 2 years, counting on from the first participant included. The study population is pregnant patients with a diagnosis of placenta accreta spectrum who visits any of the participating medical centers, and also obstetrician-gynecologists working in participating medical centers.
The centers invited to participate are hospitals or clinics that already have knowledge in how to apply the surgical staging of PAS, and the topographic classification and have experience using it.

The present study is a prospective multicenter study consisting of a cohort of patients with prenatal or intraoperative diagnosis of PAS, evaluating the clinical outcomes of the group of patients found in each category of the topographic classification. In addition, an approach to evaluate the acceptability of this classification among the obstetrician-gynecologists of the participating medical centers will be included.

Questions about this trial
What is this clinical trial studying?
An observational study of Placenta Accreta, run by Fundacion Clinica Valle del Lili at 1 site in Colombia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 13 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Colombia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Albaro J Nieto-Calvache, MD (6023319090 ext. 4022, albaro.nieto@fvl.org.co), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Days of postoperative hospitalization (time frame: From the day the surgery is performed until the day of discharge or the date of death from any cause, whichever occurs first, evaluated up to 42 days.). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05922397, which also lists 29 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Feb 2025.
