[Aneurysmatic changes of renal arteries in the angiogram (author's transl)]

10 out of 1600 angiographies of the kidneys or abdominal aortograms showed a renal aneurysm and in one patient an arterio-venous fistula following renal biopsy. Renal artery aneurysms are found mainly at the branching of the main renal artery. Fibromuscular dysplasia plays a large part in its development. Because of the danger of rupture every renal aneurysm should, if possible, be treated by surgery.
