Future perspective:

A hypothetical treatment option could be this that product of conception is removed from the rudimentary horn laparoscopically, and the rudimentary horn and the main horn united by Laparoscopic Strassman’s Metroplasty. This could increase the uterine cavity area for pregnancy and probably restore better reproductive outcome. But feasibility of surgery, and obstetrical morbidity of the patient will have to be seen, and will require great deal of counselling of the couple. Such procedures have been done before for treatment of hematometraand chronic pelvic pain with fairly good outcome [18].
