Conservative treatment of ectopic pregnancies using a single echo-guided injection of methotrexate into the gestational sac

The authors describe the possibility of the conservative treatment of five early ectopic pregnancies. A single injection of methotrexate into the tubal gestational sac was performed under vaginal ultrasound guidance. In all five cases, a clear ectopic gestational sac could be visualized.

At the same time, plasma beta-hCG gradually decreased to zero after a maximum time period of 25 days. Subsequent hysterosalpingography performed on all of the women demonstrated bilateral normal patent tubes. It is concluded th…
