胎盘早剥子宫卒中,简称子宫胎盘卒中(uterop-lacental apoplexy)。因Couvelaire(1912年)最先报道本征象,故又称为库弗菜尔氏子宫(Coureai-re uterus)。胎盘早剥是指胎盘于妊娠晚期或于分娩期胎儿娩出之前,出现底蜕膜血管破裂出血,使胎盘母体面与子宫壁分离。若剥离的部位起自胎盘中央,胎盘四周边缘仍附着于子宫壁上,血液不能外流,局部形成胎盘后血肿并逐渐增大,此时属于重型(隐性出血型)胎盘早剥。胎盘后无法外流的血液逐渐增多,胎盘与子宫壁之间的压力逐渐增大,使流出的血液只能向子宫肌层方向浸润,致使受湿润的子宫肌纤维分离。当子宫肌纤维间充满血液时,可以导致肌纤维断裂、变性等病理改变,严重者血液渗入到子宫肌层深部,直
Placental abruption of uterine stroke, referred to as uteroplasty (uteroplasty apoplexy). Because Couvelaire (1912) first reported this phenomenon, it is also known as the Couvrell’s Palace (Coureai-re uterus). Placental abruption refers to the placenta in the third trimester of pregnancy or during labor before delivery of the fetus, the bottom decidualized blood vessels rupture bleeding, so that the separation of the placenta and the uterine wall. If the stripped part from the center of the placenta, the placenta around the edge is still attached to the uterine wall, the blood can not flow, the local formation of placental hematoma and gradually increased, this time belong to heavy (recessive type) placental abruption. After the placenta can not be out of the blood gradually increased, the pressure between the placenta and the uterine wall gradually increased, so that the outflow of blood can only infiltrate the direction of the myometrium, resulting in moist uterine muscle fiber separation. When the uterine muscle fibers filled with blood, can lead to muscle fiber rupture, degeneration and other pathological changes, severe cases of blood into the myometrium deep, straight
