The value of ultrasound for early classification in cesarean scar pregnancy

Objective: To investigate the value of ultrasound early classification in Cesarean scar pregnancy (CSP). Methods: Ultrasound images were utilized to categorize 95 CSP patients by cavity, partial, and complete types based on the villi implant positions of the embryos. The patients also were categorized according to signs of scar blood flow levels. CSP patients were separated by type for conservative or interventional treatment and cure rates were assessed. Results: The cure rate was 96.56% for the cavity types, 76.19% for the partial types and 45.83% for the complete types (chi(2)=5.432, P=0.020<0.05; chi(2)=17.379, P=0.000<0.001). The total cure rate for the interventional group was 84.48% and for the conservative group it was 59.46% (chi(2)=7.492, P=0.006<0.05). Conclusion: Although the interventional therapy was an effective method for most CSP patients, the conservative therapy was also effective for types with shallow implantation of the gestational sacs. The use of ultrasound for the early classification of CSP patients evidenced important clinical significance. Treatment should be individualized and which types should be considered.
