[The pregnant and non-pregnant rudimentary horn of an uterus (author's transl)].

In the past 10 years three cases of pregnancy in a rudimentary horn of a double uterus and one case of haematometra were observed at the second university hospital for women in Vienna. The problems of the development of a pregnancy in the uterine cavity of a rudimentary horn which is not connected to the main uterine cavity are discussed. The clinical course of such a pregnancy is discussed reviewing our own cases and those reported in the literature.
