Abstract:

Objective  To evaluate the treatment of caesarean scar pregnancy. Methods  Data of 102 patients with caesarean scar pregnancy treated during Jan. 2006 to Feb. 2012 were retrospectively reviewed with clinical cohort study. The patients were divided into 3 groups, including muscle and intrauterine cavity injection of methotrexate (MTX, Group A), MTX therapy followed by ultrasound-guided suction curettage (Group B) and uterine arteries embolization followed by low vacuum aspiration (Group C). Results  The mean resolution time of serum β-hCG, time taken for CSP mass to disappear, time of vaginal bleeding, hospital stay and costs were statistically different in the three groups (P<0.05). The success rate for Group A, B and C were 92.86%, 88.52% and 84.62%, respectively, with no statistically significant difference (P>0.05). Conclusion  All three therapies yield high success rate, while muscle and intrauterine cavity injection of methotrexate is effective, cheap and non-invasive.
