Objective:To provide a new direction for the diagnosis and treatment of recurrent spontaneous abortion.Methods:The clinical data of one patient with repeated abortion were retrospectively analyzed. The patient's blood type was finally confirmed to be the rare p blood type. Considering that the patient was in the second trimester and had low-implantating placenta, a pre-stored autologous blood preparation scheme was developed after multidisciplinary consultation.Results:The induction of labor was successful in this case.Conclusion:After excluding the common causes of abortion, obstetricians should screen pregnant women for irregular antibodies in blood, and also provide suggestions for perinatal blood preparation for rare blood group pregnant women. It is feasible to adopt pre-stored autologous blood preparation as one of the emergency transfusion pre-plans.
