Early pregnancy placental abruption is a serious complication of acute onset, rapid progress, diagnosis and treatment may not be able to endanger the mother’s life now decades of etiology and diagnosis and treatment of a large number of experimental studies are as follows. 1 The main causes are as follows 1.1 pregnancy-induced hypertension syndrome or maternal vascular disease pregnancy-induced hypertension (hereinafter referred to as PIH), essential hypertension, chronic hypertension with systemic vascular disease such as chronic nephritis with hypertension The primary cause of placental abruption. Retrospective analysis over the past 10 years, the factor accounted for the first (82.5%), the pathogenesis of placental bed at the bottom of the decidual spiral arteries spasm, acute atherosclerosis, causing distal capillary ischemia, necrosis, rupture The bleeding, the formation of hematoma, and gradually expanded so that the placenta
