Vaginal radical trachectomy RT ligates and cuts several arteries supplying the uterus. Changes of blood supply to the uterus in two patients who experienced pregnancy and delivery were studied by using 3-D CT scanning. Effects of changes of blood supply to the uterus on the pregnancy courses were also examined. Methods. Vascular distribution in the uterus was studied in two patients who received vaginal RT after delivery. Effects of changes of vascular distribution after vaginal RT were studied with respect to pregnancy courses and cervical functions. Results. New arterial vascularization from the ascending branches of uterine arteries or other arteries occurred and these new vessels seemed to supply blood to the remaining cervix. Differences of fetal growth and histopathological changes in the placenta between the two patients could not be detected. Conclusion. Ligation and cutting of several supplying arteries by RT induces new areterial vascularization and it does
