[Cervical pregnancy]

The cervical pregnancy is one of the states that make the direct life-threatening for a woman. A death rate is about 20-60%. It is estimated that the cervical pregnancy occurs once for 16000 cases of normal pregnancy. Etiology is not recognized well yet. It is assumed that one of the major causes for implantation of fetal egg within a uterine cervix is the decidual metabolism of endometrium. A hyperestrogenic period after fertilization causing a change of oviduct kinetics may be conducive to nidate the egg in the cervical canal. Surgical traumas of uterus, multiparity, development anomaly, tumours of reproductive organs may cause the change of the fetal egg localization. The great significance is attributed recently to an atrophy of transparent tunica and involving a retardation of egg innidiation ability what results in localization of pregnancy in the cervical canal. In case of this type of ectopic pregnancy the only way to recognize it is a precise medical history of a patient, clinical picture and gynaecological examination. An early recognition of the cervical pregnancy prevents of metrorrhagia which is so dangerous for life. It is commonly assumed that a therapy to be chosen is removal of uterus. Using this background one case of the cervical pregnancy observed for the last 20 years in the department materials is described which recognition before treatment was settled based on the presented clinical argumentation.
