Multiple small aneurysms are seen on aortography in which condition
a. Takayasu's arteritis is an inflammatory and stenotic disease of medium- and large-sized arteries characterized by a strong predilection for the aortic arch and its branches. For this reason, it is often referred to as the aortic arch syndrome.
b. Takayasu's arteritis is an uncommon disease with an estimated annual incidence rate of 1.2–2.6 cases per million. It is most prevalent in adolescent girls and young women.
c. The disease involves medium- and large-sized arteries, with a strong predilection for the aortic arch and its branches; the pulmonary artery may also be involved.
d. The involvement of the major branches of the aorta is much more marked at their origin than distally.
e. The diagnosis of Takayasu's arteritis should be suspected strongly in a young woman who develops a decrease or absence of peripheral pulses, discrepancies in blood pressure, and arterial bruits.
f. The diagnosis is confirmed by the characteristic pattern on arteriography, which includes irregular vessel walls, stenosis, poststenotic dilatation, aneurysm formation, occlusion, and evidence of increased collateral circulation.
g. Complete aortic arteriography by catheter-directed dye arteriography or magnetic resonance arteriography should be obtained, in order to fully delineate the distribution and degree of arterial disease
