Five cases of placenta accreta and percreta are reviewed. Three cases, one a recurrence in the same patient, presented with acute abdominal pain; in one case perforation resulting from placenta percreta was discovered at laparotomy. In another case, placenta accreta was recognized during cesarean delivery. Total or subtotal hysterectomy was performed in three cases; piecemeal removal of placental tissue and closure of the tear was performed in two of the patients. There were no maternal deaths, but the infants were stillborn in three cases of perforation or uterine rupture.
