title: [Uterine Rupture at 18 Weeks of Pregnancy in the Context of Malformed Uterus].
abstract: Birth defects of the female genital tract are relatively common and often asymptomatic. Despite the pregnancy outcome can be favorable, adverse obstetric outcomes are described in women with uterine malformations. The authors report the case of an obstetric emergency which enhances the possibility of a very adverse and rare outcome of uterine rupture in a left hemi-cavity of a bicornuate uterus away from the term, at 18 weeks of pregnancy, in a pregnant woman with history of caesarean in the right hemi-cavity and with placenta increta. A malformed uterus with a primitive type cavity has lower distensibility of the wall with the progression of the pregnancy and facilitates the development of abnormal placentation forms, increasing the risk of uterine rupture in the first and second trimesters. The knowledge of the existence of a congenital uterine anomaly in the preconceptional period is of primary importance.
