[Cervical pregnancy. A report of a case and literature review].

The cervical pregnancy is a rare clinical illness among the ectopic pregnancies; the diagnosis at the moment is made by means of ultrasonography, which shows an empty uterus and a gestation in cervical channel. At the moment the preservative treatment can be made with methotrexate, without determining of precise way the factors of fault for this handling, leaving the single surgical treatment in emergency situations, avoiding the uncontrollable haemorrhage. This paper reports the case of a patient with a cervical pregnancy of nine weeks, live, with initial determination of corionic gonadotrophin hormone of 68,919 mUl/mL; reason why it is decided to interrupt the gestation being applied two doses of methotrexate; first IV of 85 mg and second with intraamniotic application. The evolution of the gestation was towards the involution and absorption of the gestational coat, the sub-unit concentrations corionic gonadotrophin hormone beta presented decrement, until undetectable, with good clinical and functional results. The gestational coat was reduced, the embryo lost beat and the gonadotrophin were in decrement until zero, with clinical evolution with stained solely haematic, without haematological and functional repercussions. Criteria of fault of the preservative treatment with methotrexate are not defined, although due the peculiarity of this illness, it is not possible to make a more extensive study, but by the reproductive benefit in young patients, it would be adapted to take it in to account like option instead of the hysterectomy.
