[Arteriography in polyarteritis nodosa. Diagnostic findings and value of repeated examinations (author's transl)]

Abstract

The results of 18 abdominal arteriographies (general aortography, selective renal, superior mesenteric, and coeliac arteries) in 11 patients with polyarteritis nodosa (P.A.S.), are reported and analyzed. In all tissues, the frequency of the lesions was 66% for micro-anéurisms, 100% for stenoses, and 83% for thromboses. These are seen mainly in the kidney, but isolated lesions may occur in the liver and gastro-intestinal tract. As they vary with time and the area affected, selective contrast studies of the main stems of the abdominal aorta and, in some cases, repeated arteriographic examinations, are necessary.
