[Importance of intravenous digital subtraction angiography in the diagnosis of aneurysms in the region of the abdominal aorta].
The arterial vessels can be examined with satisfactory relevance via intravenous DSA using a relatively small amount of contrast medium. An aneurysm first diagnosed via sonography in the region of the abdominal aorta was confirmed in this manner in 19 patients. In 7 of these cases, it was also possible to diagnose a stenosis in the renal artery region. This method can supply exact information on the size, position and extension of the aneurysm--since the equipment has been technically improved--even in the case of kinking of the vessels. It can also supply information in the relationship of the aneurysm to visceral arteries, on the degree of calcification of the vessel walls, and on the additional occurrence of vascular stenoses. Hence, we are of the opinion that intravenous DSA is the method of choice after sonography has been performed and that it is superior to CT within the framework of preoperative examinations of aneurysms of the abdominal aorta.
