  • Title: Fibromuscular dysplasia of renal arteries: comparison of intravenous digital subtraction angiography with conventional angiography.
    Author: Illescas FF, Braun SD, Cohan RH, Sussman SK, Saeed M, Dunnick NR.
    Journal: Can Assoc Radiol J; 1988 Sep; 39(3):167-71. PubMed ID: 2971048.
    Abstract:
    Intravenous digital subtraction angiography (IV-DSA) was compared with conventional arteriography (CA) in 14 patients with fibromuscular dysplasia (FMD) of at least one renal artery. IV-DSA identified 29 of the 34 renal arteries detected by CA. A diagnostic quality IV-DSA examination was obtained in 23 of 29 renal arteries (78%). In adequately imaged renal arteries, IV-DSA correctly identified 12 of 20 FMD renal arteries, misdiagnosed 8 FMD renal arteries as normal and correctly identified 3 normal renal arteries. These poor results, due to poor spatial resolution and subtraction artifacts inherent in the IV-DSA system, warrant careful interpretation of negative examinations and further evaluation of high risk patients.
