Objectives: To analyze the correlation between ultrasound typing and treatment modality of patients with an intrauterine
ectopic pregnancy (cervical and cesarean scar).
Material and methods: We retrospectively enrolled 65 patients diagnosed with cesarean scar pregnancy (CSP) or cervical
pregnancy (CP) between February 2014 and May 2018. The cases were divided into two types according to the ultrasound
presentation with a gestational sac (GS, type I) or a heterogeneous mass (HM, type II). Type I was further divided into type
Ia (< 8 weeks) and type Ib (≥ 8 weeks); type II was defined as type IIa (with poor or no vascularity) and type IIb (with rich
vascularity). Three treatment methods were applied in each group.
Results: Of included cases, there were 53 CSP and 12 CP. There was no significant difference between Type I and Type
II groups in any variable. The beta human chorionic gonadotropin (β-hCG) level and gestational age of type IIb were
significantly higher compared to type IIa (p < 0.05). There was a positive correlation between ultrasound categories and
treatment methods (rs = 0.723, p = 0.000). Analysis of CSP cases of initial treatment failure indicated success rate of initial
dilation and curettage (D&C) was dependent upon ultrasonic types, mean sac diameter, gestational age, hCG level, and
number of cesarean sections.
Conclusions: The features of ultrasound imaging might provide an additional reference for the selection of clinical treatment
