[Treatment of cervical pregnancy with systemic methotrexate and KCI solution injection into the gestational sac--case report and review of literature].

We report a case of a 6-week cervical pregnancy successfully treated with systemic methotrexate and gestational sac biopsy with 15%-calcium chloride solution injection. Serial monitoring of human chorionic gonadotropin levels, combined with ultrasound examinations, confirmed spontaneous miscarriage. Applied treatment allowed to avoid hysterectomy and preserve the patient's fertility.
