Single-dose intramuscular methotrexate treatment of cervical ectopic pregnancy. A case report.

BACKGROUND
Cervical ectopic pregnancies (CEPs) are increasingly being managed conservatively. However, the efficacy of specific conservative approaches such as the single-dose intramuscular (IM) methotrexate (MTX) therapy has not been evaluated. We reportthe successful management of 2 consecutive CEPs in the same patient with single-dose IM MTX therapy, and review published cases of CEPs treated with a similar regimen, to determine the efficacy of this approach.


CASE
In our case, both CEPs resolved with single-dose IM MTX, and the patient subsequently had a successful term delivery. A Medline/OVID English language search, covering the period 1982-2012, identified 38 additional cases of CEPs treated with single-dose IM MTX. Of the total 40 cases analyzed, including our 2 cases, 30 (75%) were successfully treated, with complete remission. Of the 27 cases with no embryonic cardiac activity, 25 (93%) were successfully treated with single-dose IM MTX.


CONCLUSION
Appropriately selected cases of CEPs can be successfully managed with single-dose IM MTX with very low complication rates and preservation of future fertility potential.
