[The cicatricial uterus and uterine dehiscence. Apropos of 20 cases].

The authors intend to study 20 cases of uterine dehiscence or pre-rupture of cicatricial uterus owing to a better maternal and fetal prognosis as opposed to complete ruptures. They define the risks factors, i.e. aspects susceptible to weaken the scar, in the past history and during the pregnancy in progress. Finally, the study of semiology permits to establish the conditions of an early diagnosis of dehiscence. These results lead to insist on prevention which is based on a thorough knowledge of the past history and the obstetrical findings, the cephalo-pelvic comparison and the quality of the uterine scar.
