Incidence and Clinical Implications of Placenta Accreta Spectrum after Treatment for Asherman Syndrome

To investigate the incidence, predictors, and clinical implications of placenta accreta spectrum (PAS) in pregnancies after hysteroscopic treatment for Asherman syndrome (AS). This is a retrospective cohort study, conducted through a telephone survey and chart review. Minimally invasive gynecologic surgery center in an academic community hospital. Database of 355 patients hysteroscopically treated for AS over 4 years. We identified patients who achieved pregnancy past the first trimester and evaluated the incidence and predictors for PAS as well as associated clinical implications. Telephone survey. We identified 97 patients meeting the inclusion criteria. Among these patients, 23 (23.7%) patients had PAS. History of cesarean delivery was the only variable statistically significantly associated with having PAS (adjusted odds ratio 4.03, 95% confidence interval 1.31–12.39). PAS was diagnosed antenatally in 3 patients (14.3%), with patients having placenta previa more likely to be diagnosed (p
