    Abstract:
    The development and technique of a x-ray examination for prenatal and post-mortem angiography is presented. After elaboration of an appropriate method for preservation and treatment of the embryos the angiographic procedure was technically evolved and performed on 55 cow-, 40 pig-, and 5 sheep embryos and fetuses with a vertex- breech- length between 11 and 222mm. Selective filling of the arterial and venous system with good opacification of the peripheral vessels and capillary plexus could be regularly achieved by means of thin catheters or extended glass cannulas which were inserted into the umbilical arteries and veins or the vessels of the foetal membrane. By means of this technique the radiological embryology of the vascular development of different species can be studied in great series and investigated with regard to onto- and phylogenetic aspects. This prenatal angiographic technique can also be applied to man as has been proven by angiograms of 4 human embryos and fetuses aged between 6 weeks and 5 months.
