The Need for Presurgical Evaluation for Placenta Accreta Spectrum

Area of Science:

• Perinatology
• Maternal-Fetal Medicine
• Diagnostic Imaging

Background:

• Current staging of placenta accreta spectrum relies on retrospective histopathology, limiting its clinical utility for presurgical planning.
• Existing staging methods do not adequately incorporate crucial factors influencing patient risk and morbidity.

Purpose of the Study:

• To advocate for a paradigm shift towards presurgical staging of placenta accreta spectrum using clinical and imaging data.
• To introduce a novel, data-driven model for antenatal risk stratification of placenta accreta spectrum.

Main Methods:

• Review of past staging attempts for placenta accreta spectrum.
• Development of a new data-driven model integrating clinical and imaging characteristics for presurgical staging.
• Proposal for incorporating the model as a clinical decision aid.

Main Results:

• Histopathologic grading is inadequate for antenatal planning of placenta accreta spectrum.
• Previous pre-delivery staging methods have overlooked key risk and morbidity factors.
• A new data-driven model has been developed for clinical integration to assess individual patient risk.

Conclusions:

• A transition to presurgical staging using clinical and imaging data is necessary for effective placenta accreta spectrum management.
• The proposed data-driven model can assist clinicians in determining patient risk and guiding appropriate care.
• Implementation of this model can improve patient outcomes through optimized workup and management strategies.
