[Primary sterility and cervical pregnancy. A case report].

Fortunately cervical pregnancy, an ectopic gestation that frequently represents obstetric urgency, is a rare entity. We present here the case of a woman who developed cervical pregnancy despite no risk factor associated with ectopic pregnancy was identified. The patient came to the office because of primary sterility of 4 years of evolution. Among her background she reported previous cervical surgery due to benign pathology. She reached pregnancy after medical and surgical treatment. In the week eleven of gestation, the patient presented to the hospital with clinical symptoms of abortion. An ultrasound revealed abdominal pregnancy. Laparotomy was "white", cervix was found enlarged with the external orifice closed, suggesting cervical pregnancy. Conservative treatment consisted in cervical evacuation, endometrial curettage and vaginal tampon. She evolved satisfactorily. We do not know about any previous report of cervical-pregnancy associated with cervical surgery and sterility. We also recognize the need to increase the number of similar cases to generalize results. Thus, it is important to highlight in this case the absence of known risk factors for cervical pregnancy and the background of cervical surgery and sterility. Therefore, we recommend to search for antecedents of cervical surgery and sterility when cervical pregnancy is suspected.
