[Arteriomegaly. Apropos of 6 cases].

Six cases of megalodolichoartery (M. D. A.) or arteriomegaly are reported. The arteriographic characteristics of the condition are reviewed: abnormally dilated and tortuous arteries, frequently aneurysmal, sometimes the site of obstruction by obliterative arteriosclerosis or embolism. Although clinically the relation between M. D. A. and arterial atheroma appears close, underlying abnormalities of elastic tissue cannot be excluded from the aetiology of the disease.
