Management of interstitial ectopic pregnancies with a combined intra-amniotic and systemic approach.

Background: Approximately 2% of all pregnancies are ectopic; of these, 4% are interstitial or cervical. There exists no clear consensus as to whether surgical or medical management is superior.

Case: We present three cases of advanced nonfallopian tube ectopic pregnancies from 6 to 8 weeks of gestation.
