A horn pregnancy does not necessarily turn out to be a relatively rare pregnancy in a special part of the uterus, as the fertilized egg is implanted in the horn of the uterus at the junction of the uterus and the fallopian tubes. type I: an intrauterine horn pregnancy, in which the gestational sac grows mainly inside the uterine cavity, the horn of the uterus is not significantly convex and there is a low risk of rupture of the myometrium of the horn of the uterus. type II: an extrauterine horn pregnancy, in which the gestational sac grows mainly outside the horn of the uterus, the The risk of rupture of the myometrium at the horn of the uterus is higher. The treatment of horn pregnancy is mainly surgical; in some patients the gestational sac grows mostly inside the uterine cavity and there is a possibility of pregnancy to full term and vaginal delivery. In this type of patients, if there is a strong demand to continue the pregnancy, expectant therapy can be performed, i.e., the pregnancy should be continued with close monitoring, and in case of complications, the pregnancy should be promptly terminated.
