Translumbar Aortography

Author and Disclosure Information


SATISFACTORY visualization of arterial circulation by roentgen examination is a comparatively recent accomplishment. This is true of translumbar aortography, although it was described by Dos Santos before the Surgical Society of Paris in 1929.1 This diagnostic procedure did not meet with immediate acceptance, however, and almost a quarter of a century elapsed before it became recognized as a valuable diagnostic aid. Improvements in contrast media and technic have contributed to making arteriography a safe and simple examination.2,3

The original application of aortography was chiefly in the field of urology to differentiate between various types of renal lesions.4–8 Useful information concerning potential renal function can be obtained from a roentgenographic study of renal blood supply.

In recent years, aortography has been found to be of equal or even greater value in the diagnosis of vascular pathology involving the abdominal aorta and its immediate branches.9,10 Suspected conditions such as aneurysm and complete or partial occlusion may now be confirmed or excluded by this means.

The technic of translumbar aortography has been adequately described in the literature. We have used the simple technic of syringe injection employed by Smith et al.3 The choice of the opaque media, whether it be sodium iodide, neo-iopax or diodrast is largely the preference of the physician making the injection. We have found no appreciable difference in results between 75 per cent neo-iopax and 70 per cent diodrast. Sodium iodide, 80 per cent, will give a contrast shadow somewhat more dense than the other media and may. . .
