Psychological impact of Placenta Accreta Spectrum disorders (PAS) and risk of Post-Traumatic Stress Disorder (PTSD): A cross-sectional study

Abstract

Objective

Placenta Accreta Spectrum disorders (PAS) are a group of obstetric complications with an increasing incidence. The high maternal and neonatal morbidity and mortality associated with PAS leads to concerns about the negative psychological impact, and even the risk of developing Post-Traumatic Stress Disorder (PTSD). The aim of this study was to assess the psychological impact of PAS diagnosis and intervention during pregnancy and postpartum and its potential association with PTSD.

STUDY DESIGN: A cross-sectional study was conducted, including cases of PAS FIGO grade 2 and 3 treated at University Hospital Center São João, between 2010–2023. Only cases with histopathological confirmation after peripartum hysterectomy were included. Data were obtained from electronic medical records (Sclinic® and Obscare®). The impact of Event Scale – Revised (IES-R), a validated questionnaire, was applied, after surgery for PAS, to assess the psychological impact of PAS diagnosis and treatment.

Results

Fourteen cases of PAS were identified. The mean maternal age was 36.8 years. Approximately 86 % of cases had antenatal suspicion. The mean gestational age at delivery was 34 weeks. Of the 14 women, only 11 responded to the request to participate in the study (7 interviewed in person and 4 remotely). Four women had IES-R scores indicative of high risk of PTSD (IES-R>33 points), one had an intermediate risk (IES-R between 24–32 points), and 6 fell into the low-risk category. The mean score was 22.4 points. The analysis of IES-R results by clusters showed higher scores in the intrusion category, which relates to intrusive and unwanted thoughts, images and memories.

Conclusion

Given the high morbidity and mortality described in women with PAS, the risk of PTSD should be acknowledged, motivating early intervention to prevent the development of severe and potentially chronic symptoms. Supportive measures and psychiatric and/or psychological follow-up should be promptly implemented, ideally by multidisciplinary teams.
