Intravenous digital subtraction angiography in patients with Aorto-arteritis (Takayasu's)
Tóm tắt
Aorto-arteritis is one of the commonest vascular diseases in China as well as in Japan and other parts of Asia. The results of digital subtraction angiography (DSA) in 50 patients with aortoarteritis are reported, and the merits and demerits of intravenous (IV) DSA in the diagnosis of this entity are evaluated. Among the 51 studies performed on 50 patients, IV DSA was used in 48, intraarterial (IA) DSA in 3, and good-to-excellent visualization was obtained in 96% of patients. Aorto-arteritis of varying severity and involving the thoraco-abdominal aorta, the iliac arteries, and other major branches was clearly demonstrated by IV DSA. IV DSA, as compared to our previous experience with conventional arteriography in this entity, may be substituted for conventional arteriography in most patients. A large dose of contrast media needed for a complete study is a major deficiency of IV DSA, and it also has limitations for showing the intrarenal arterial branches.
