Abstract
Reynaldo dos Santos and collaborators A. C. Lamas and J. P. Caldas presented their experiences in abdominal aortography (ao.), in 1929 (cited from R. dos Santos 1933). in 1937 R. dos Santos published a more detailed paper, in which he maintained the great advantages and harmlessness of the method. Although an occasional paper appeared, it seems that little attention was paid to this method elsewhere. During recent years a few authors have again adopted the method, and reported excellent results. (Nelson, Wagner, Keller-Doss, Weyde, Lindstrom, Cedermark-Henschen-Lindblom, Olsson.)
