Gao L, et al. - Researchers performed a comparison of the efficacy of intra-arterial methotrexate (MTX) infusion combined with uterine artery embolisation (UAE) and uterine curettage with that of UAE and curettage without MTX infusion for the treatment of cesarean scar pregnancy (CSP). They noticed a significant improvement in post-operative recovery with the addition of intra-arterial MTX to UAE and curettage, despite no significant effect on the success rate and bleeding events. Observations thereby suggested that addition of intra-arterial MTX might not be necessary.
