Pivotal points in interstitial pregnancy: New insights in conservative medical treatment of non-ruptured interstitial pregnancy

Abstract

We report the efficacy of a minimally invasive approach of the multidose protocol with methotrexate (MTX) in the management of three cases of interstitial pregnancy (IP), with elevated serum β-hCG in two cases. New considerations and management strategies are discussed. Successful termination of IP and in one case, a subsequent successful pregnancy, was achieved. The process led to the development of an enhanced understanding of diagnostic modalities and their limitations, with regard to the particular entities under discussion. We also focused attention on pivotal points and anatomical features in the management of this dangerous occurrence. Long-term results with careful follow-up were analysed by instrumental procedure. This hazardous type of ectopic pregnancy can be managed with systemic administration of MTX, also in patients with elevated β-hCG values. The present report underlines that an integrated approach in early diagnosis, multidose treatment and close follow-up, are essential forms of medical management.
