[3 new cases of pregnancy of the uterine horn].

Three new cases of pregnancy in the uterine cornu are described. Three types of localisation are grouped under this heading : interstitial pregnancies, intra-mural pregnancies and angular pregnancies which all have identical mechanisms of pathogenesis (uterine scars) and identical patterns of clinical progression (complicated by uterine rupture). The authors discuss the methods of diagnosis. A constant feature is pain with an asymmetrical uterus. Laparoscopy is often able to make the diagnosis of pregnancy in the uterine cornu, without being able to determine the exact site. Early diagnosis results in conservative surgical treatment.
