The management of caesarian scar pregnancy with or without a combination of methods prior to hysteroscopy: Ovarian reserve trends and patient outcomes.

STUDY

OBJECTIVE

This study compared the efficacy and safety of a combination of uterine artery embolization or methotrexate before hysteroscopy in the treatment of cesarean scar pregnancy.

METHODS

We divided 276 cesarean scar pregnancy patients into three groups. Group A underwent direct hysteroscopy; Group B received uterine artery embolization plus hysteroscopy; Group C received the systemic administration of methotrexate prior to hysteroscopy.

RESULTS

The patients in Group A lost significantly more blood than those in Groups B (P < 0.05). There were no significant differences between the three groups with regards to massive hemorrhage and transfusion (P > 0.05). None of the patients required hysterectomy. Group A was also associated with a significantly shorter period of hospitalization, reduced medical costs, and fewer adverse events than either Group B or C (P < 0.05). Moreover, among women of advanced age (≥35y), the levels of serum anti-Mullerian hormone in Group B were significantly lower than those of the baseline group (P<0.05), which were significantly lower than those in Group A after surgery (4.22 ± 2.35 vs 2.78± 1.89 ng/ml, P < 0.05).

CONCLUSION

Direct hysteroscopy is a reliable treatment option for most early type I cesarean scar pregnancy patients with a gestational sac. A combination of methotrexate and uterine artery embolization before hysteroscopy in these patients has limited remedial effects. uterine artery embolization may reduce ovarian reserve in patients aged ≥35y.
