Pathologic Diagnosis of Placenta Accreta Spectrum

Area of Science:

• Obstetric Pathology
• Perinatal Pathology
• Gynecologic Pathology

Background:

• Existing guidelines from the International Federation of Gynecology and Obstetrics (FIGO) were published in July 2019.
• A need for standardized pathologic diagnosis and reporting of Placenta Accreta Spectrum (PAS) was identified.

Purpose of the Study:

• To develop consensus recommendations for the pathologic diagnosis and reporting of Placenta Accreta Spectrum (PAS).
• To align with FIGO terminology and guidelines.
• To establish standardized classification and reporting for PAS.

Main Methods:

• Convening of an expert Placenta Accreta Task Force by the Society for Pediatric Pathology (SPP) Perinatal Subcommittee in October 2019.
• Development of recommendations for gross and histopathologic examination.
• Creation of a standardized pathologic classification system and reporting guidelines.

Main Results:

• Consensus recommendations for the pathologic diagnosis of PAS have been established.
• Guidelines for gross and histopathologic examination are provided.
• A standardized pathologic classification system and reporting framework are proposed.

Conclusions:

• The developed guidelines aim to standardize the pathologic diagnosis and reporting of Placenta Accreta Spectrum (PAS).
• These recommendations will facilitate consistent evaluation and improve communication among healthcare providers.
• The work aligns with international standards, enhancing the quality of perinatal pathology reporting.
