BACKGROUND: The aim of this study was to assess the clinical outcomes of conservative treatments for cervical ectopic pregnancy (CEP).
MATERIAL AND METHODS: The series of CEP cases at our hospital between 2009 and 2016 were reviewed retrospectively. The patients were treated using systemic methotrexate infusion (MTX group, n=9), angiographic uterine artery embolization (UAE group, n=11), or transcatheter intra-artery methotrexate infusion combined with UAE (UAE+MTX group, n=13). Clinical outcomes, complications, and fertility were evaluated.
RESULTS: The median serum β-hCG was 6449 mIU/mL for MTX group, 17384 mIU/mL for UAE group, and 21361 mIU/mL for UAE+MTX group. The difference was statistically significant. In the MTX group, 1 patient developed hepatotoxicity and 2 patients occurred continuous vaginal bleeding during curettage. These 3 patients were successfully treated with emergency UAE. In the UAE group, 2 patients had vaginal re-bleeding on postoperative day 17 and 26, respectively, and received a second UAE procedure. In the UAE+MTX group, no patients developed severe complications. Moreover, a quick regression of serum β-hCG level, shortened recovery of normal menstruation, rapid cervical mass elimination, and a short hospital stay were observed in patients of the UAE+MTX group.
CONCLUSIONS: The triple therapy of transcatheter intra-arterial methotrexate infusion combined with UAE followed by immediate curettage is feasible and advantageous in treating CEP.
