Summary

At present, there is no unified standard for the treatment of missed abortion in clinical practice. This study intends to collect clinical data of this type of disease to compare the efficacy of different treatments, and on this basis, presuppose the synergistic effect of different doses of estrogen in the process of drug induction, conduct statistical analysis of the efficacy, evaluate whether the treatment plan can achieve the therapeutic effect while reducing the occurrence of complications, and provide an effective basis for the subsequent clinical treatment of missed abortion. This study is divided into two parts. The first part is a retrospective analysis to explore the differences between missed abortion surgery and drug treatment, clinical efficacy and reproductive outcomes; the second part is a prospective study to explore the effects of different doses of estrogen combined with surgery or drug abortion on the efficacy of missed abortion in early pregnancy, and explore the best clinical treatment method for missed abortion.
