Abstract：Objective To analyze the causes of prenatal misdiagnosis of atypical abruption placentae , in order to guide clinical diagno-sis.Methods 180abruptionplacentaepatientsacceptedbythehospitalfromJanuary,2010toJanuary,2014wereselectedasthere-search object , and retrospective analysis was done .According to the diagnosis results , they were divided into Misdiagnosis Group ( n=48 ) and Diagnosis Group ( n=132 ) .The predisposing factors , clinical symptoms and signs , placental abruption area , the total amount of bleeding and placental location of two groups were compared .Results Patients with predisposing factors in Misdiagnosis Group was signifi-cantly less than in Diagnosis Group (P<0.05).And the main predisposing factors in Misdiagnosis Group were odinopoeia and hasten par-turition.Patients with clinical symptoms and signs , such as abdominal pain and vaginal bleeding in Misdiagnosis Group was significantly less than in Diagnosis Group (P<0.05).And the main clinical symptoms and signs in Misdiagnosis Group was fetal heart monitoring ab -normal.The placental abruption area and the total amount of bleeding in Group Misdiagnosis were significantly lower than that of Diagnosis Group (P<0.05).Patients whose placenta were attached to the posterior wall of the uterus were significantly more than in Diagnosis Group (P<0.05).Conclusion The causes of atypical abruption placentae are mainly due to odinopoeia and hasten parturition .Most patients′clinical symptoms and signs are not obvious .During clinical diagnosis , various detection schemes should be adopted , and the history be combined, in order to make right diagnosis.
