The Pan-American Society for Placenta Accreta Spectrum (PAS2) grew out of shared clinical and research interests. A group of physicians first started talking about placenta accreta in 2010 at the Annual Meeting of the Society for Maternal-Fetal Medicine.  Since then, we have worked together on clinical guidelines, expert opinion pieces and research, education and outreach. 

Due to the mutli-disciplinary nature of our work, we have now grown into an independent society made up of obstetricians, maternal-fetal medicine specialists, gynecologic oncologists, anesthesiologists, transfusion medicine specialists, critical care specialists, pathologists, and scientific researchers, and more, all of whom share our united mission.
