Cervical pregnancy: three case reports and a review of the literature.

Three cases of cervical pregnancy are described: the incidence, the diagnostic approach and different therapeutic managements used for this rare type of ectopic pregnancy are discussed. The last case shows that hysterectomy can be avoided by early diagnosis and by an adequate tamponing technique to control haemorrhage. For this purpose, a three-way Dufour catheter was successfully used to rinse the uterus with heated saline, allowing evacuation of intrauterine blood after curettage and to tampon the cervix.
