In addition to generalized arteriosclerosis connective tissue disease,
systemic vasculitis as well as genetic metabolic disease are describe
d to be the cause of stenotic and aneurysmatic vessel wall alteration.
Although these causes are rather unusual, they must be considered for
the diagnosis of a generalized vascular disease with arterial occlusi
on as well as aneurysm formation to determine the appropriate procedur
e for the individual. Whereas operative treatment should be avoided as
far as possible for patients with Behcet's disease or Marfan syndrome
, it is rather indicated for any kind of juvenile arteriosclerosis wit
h arterial stenosis as well as dilatation. In this way the patient des
cribed in the following could be treated successfully by operation eve
n though the cause of the juvenile arteriosclerosis was inexplicable,
and in addition to local complications also the threatening rupture of
the aneurysm could be controlled.
