| Résumé : | It is possible by means of a radiographic leehnhpie to show up the vascular system of a 19-20-day-old live rat embryo. Scrioscopic arteriograms and phlebograms were made after inject ion of a radiopaque substance first into the umbilical vein and then into the umbilical artery. This method yielded very detailed pictures, which permitted a close examination of the normal vascular system and showed up the arterial and venous system and distinct from each other, as well as certain foetal organs. As acontrol intravascular injections of Indian ink were carried out. I his method opens up several new perspectives, rirstly. the possibility ol carrying out angiographic examinations in younger and younger foetuses by attempting to overcome the numerous technical difficulties encountered in dealing with smaller embryos and secondly, that ol employing this method to examine certain foetal ab normalities. © 1967 S.
