Intravenous methotrexate for treatment of interstitial pregnancy - A case report

BACKGROUND: Ectopic pregnancy is the leading cause of first-trimester maternal death, accounting for 9% of pregnancy-related deaths. Interstitial (cornual) pregnancies represent 6% of all ectopics but account for a disproportionately higher mortality rate. Surgical management has been the treatment of choice for interstitial pregnancies. A very limited number of articles have explored the use of intravenous methotrexate to treat cornual pregnancy as a possible conservative first-line therapy in selected, hemodynamically stable patients. CASE: A patient with a confirmed interstitial pregnancy was treated with intravenous methotrexate. The patient's beta-hCG levels decreased to zero within 9 weeks. CONCLUSION: Intravenous methotrexate was used successfully in the treatment Of an interstitual pregnancy without complications.
