Two types of vascularisation of intramural uterine leiomyomata revealed by corrosion casting and immunohistochemical study.

The blood supply of myomatous uteri collected upon autopsy was examined. The uterine vascular beds were perfused via afferent vessels with fixative followed by Mercox resin and corroded after polymerisation of the resin. The vascular casts thus obtained were examined using scanning electron microscopy. The vascular system of the uterine fibroids was also examined using immunohistochemical analysis (FVIII, factor VIII-related antigen).
