K. Eibenberger et al., STENOSES AND OCCLUSIONS OF THE ABDOMINAL- AORTA IN PATIENTS UNDER 40 YEARS OF AGE, RoFo. Fortschritte auf dem Gebiete der Rontgenstrahlen und der neuenbildgebenden Verfahren, 159(4), 1993, pp. 388-392
Stenosis or occlusion of the abdominal aorta in patients under 40 year
s of age is either due to a congenital malformation (abdominal aortic
coarctation) or due to idiopathic aortitis (Takayasu's arteritis). Som
e authors, however, consider abdominal aortic coarctation as a subtype
of Takayasu's arteritis. We evaluated 9 of our cases and 108 well-doc
umented cases from the literature to help decide the question whether
abdominal aortic coarctation is an entity of its own or a subtype of T
akayasu's arteritis. In coarctation there is a slight male predominanc
e, patients are usually younger than 20 years of age, and the short ao
rtic stenosis is suprarenal with involvement of the renal arteries. In
Takayasu's arteritis females are predominantly affected, patients are
usually over 20 years of age, and the long aortic stenosis or occlusi
on is infrarenal without involvement of the renal arteries. Abdominal
aortic coarctation must therefore be considered as a separate disease.
Aortography is important, because the morphology of aortic alteration
s often allows a radiological diagnosis.
