ABSTRACT

A polyethylene catheter was introduced into the left axillary artery to approximately the level of aortic arch as a route to introduce the heated barium-gelatin contrast media. In order to introduce the contrast medium into the ventricular system of mammals a different method was developed. The contrast media filled even small vessels distant from the injection site, remained intact for over twenty years and provided adequate radiopacity to be well demonstrated without significant streak artifact, on a clinical Multidetector computed tomography unit. The fetus was removed from the water bath and, with the aid of fluoroscopic visualization, the contrast medium was hand injected through the catheter. The injection was continued until either a rupture was noted or sufficient filling had been achieved. The upper and lower extremities were removed by the Department of Orthopaedics without any noticeable lose of the contrast media.
