Failed treatment of abdominal pregnancy with methotrexate. A case report.

BACKGROUND Methotrexate is an effective, safe, low-cost alternative to surgery for treating tubal pregnancies. To our knowledge, there have only been two other reported attempts at treating abdominal pregnancy with methotrexate. CASE Despite two courses of treatment with methotrexate, the pregnancy persisted, and laparoscopy permitted a tissue diagnosis of abdominal pregnancy. CONCLUSION Although treatment with methotrexate was not successful in this case, its potential use in abdominal pregnancies merits further investigation.
