Abstract To analyze the clinical features of different ultrasonic classification of cesarean scar pregnancy (CSP), and to explore the safe and effective treatment of CSP at early stage. Methods: 107 women with CSP were collected from January 2015 to January 2018, and they were divided into uterine cavity type group(I type group), gestational sac type group (II type group) and heterogeneous mass type group (III type group)according to the ultrasonographic characteristics. The abortion rate, times of cesarean section, and medical reasons of women were compared among the three groups. Results:Among 107 women with CSP, there were 38 women in type Ⅰ, 41 women in type II group, and 28 women in type Ⅲ group. There was significant different in medical reasons of women among the three groups (P<0.05). Most of women with type Ⅲ CSP had seen a doctor because of vaginal bleeding after medical or surgical abortion. There was significant difference in treatment of women among the three groups, most of women with type Ⅰor II CSP were treated by B ultrasoundguided uterine curettage combined with bilateral uterine artery embolization, while most of women with type Ⅲ CSP were treated by abdominal surgery of pregnant lesion clearance and scar repair. Conclusion: Ultrasonic classification of women with CSP during early pregnancy can help to select appropriate treatment for CSP, which can avoid laparotomy and hysterectomy, so it has good clinical practice significance.
