Placenta accreta spectrum (PAS) is a potentially fatal disease. A quarter of PAS cases are not detected during prenatal evaluations, so obstetricians without experience with this disease may encounter complex cases without having the necessary resources. We report a series of PAS intraoperative finding (IOF) cases and analyze useful strategies to improve patient outcomes.Four cases of PAS IOF are reported. These patients were women with previous pregnancies terminated by cesarean section, with placenta previa/anterior, and whose prenatal ultrasound did not detect PAS. Three patients were candidates for the postponement of cesarean section and/or hysterectomy. One case had active vaginal bleeding, so it was not feasible to delay surgery. Patients who benefited from delaying surgery or seeking additional help through telesupport had better clinical outcomes.Decisions about which interventions to conduct and which to delay in cases of PAS intraoperative finding can determine the clinical outcome.
