Cervical pregnancy: case reports and a current literature review.

The increasing number of reports of successful conservative treatment of cervical pregnancy, such as using the folinic acid antagonist methotrexate, constitutes a breakthrough in the management of this unusual but potentially life-threatening complication of pregnancy. We are reporting two cases of cervical pregnancy, both diagnosed in the first trimester of pregnancy. The first one was successfully treated by transvaginal ultrasound-guided administration of 2 mEq KCI intraamniotically in order to stop the fetal heart activity, followed by administration of 84 mg of methotrexate intraaminiotically (1 mg/kg); whereas in the second case, we encountered a technical failure of the above method. Both patients expressed desire to maintain their reproductive capability. These two cases gave us the opportunity to review the recent literature on cervical pregnancy.
