[Rupture of non-communicating rudimentary pregnant uterine horn in a pseudo-unicornuate uterus at 23 weeks of amenorrhea. Case report]. / Rupture d'une corne utérine rudimentaire non communicante gravide sur un utérus pseudo-unicorne à 23 semaines d'aménorrhée. A propos d'un cas.

ABSTRACT

Pregnancy in the rudimentary horn of a unicornuate uterus is an extremely rare form of ectopic gestation associated with a high risk of uterine rupture. We report the case of a pregnancy developed in a non communicating rudimentary horn of a unicornuate uterus complicated by horn rupture at 23 weeks of amenorrhea showing as an acute abdominal pain and massive hemoperitoneum. This patient's uterine abnormality was known before, as this woman has delivered two years before at term a healthy boy by cesarean section. This past pregnancy was located in the normal horn and the non communicating rudimentary horn seemed at this time normal. This uterine malformation is presented with its gynecological and obstetrical entailments as well as methods that could prevent such outcome.
