Placenta percreta is the abnormal invasion of the placenta through the myometrium and serosa of the uterus. It is the most invasive of the placenta accreta spectrum followed by placenta increta. This paper presents a case of a maternal and fetal death in the second trimester due to rupture of the uterus at the site of placenta percreta in a C-section scar. Postmortem MRI showed a large hemoperitoneum and thinning of the anterolateral uterine wall. Internal examination revealed two liters of blood in the abdomen and rupture of the anterolateral uterine wall at the site of placenta percreta in a previous C-section scar. Placenta percreta is a rare complication of pregnancy, however, it is becoming more common with the increasing rate of C-section, the most common and significant risk factor.
穿透性胎盘植入是指胎盘异常侵入子宫肌层和浆膜层。它是胎盘植入谱系中侵入性最强的类型，其次是植入性胎盘。本文报告了一例妊娠中期因剖宫产瘢痕处穿透性胎盘植入部位子宫破裂导致母婴死亡的病例。尸检磁共振成像显示大量腹腔积血和子宫前外侧壁变薄。内部检查发现腹腔内有两升血液，且在既往剖宫产瘢痕处穿透性胎盘植入部位子宫前外侧壁破裂。穿透性胎盘植入是一种罕见的妊娠并发症，然而，随着剖宫产率的上升，它正变得越来越常见，剖宫产是最常见且最重要的危险因素。
