The diagnostic utility of contrast-enhanced three-dimensional magnetic reso
nance angiography (3D MRA) was retrospectively evaluated in 24 patients wit
h Leriche syndrome. 3D MRA was performed either of the abdomen alone (n = 6
), the abdomen and chest (n = 2), the abdomen and lower extremities (n = 12
), or of all stations (n = 4), MRA image sets were evaluated regarding the
location of the aortic occlusion, the presence of concomitant occlusive dis
ease affecting the renal and visceral arteries, the type and extent of coll
ateralization, and the level of the most proximal graftable arterial segmen
ts. Intravenous digital subtraction angiography was available for correlati
on in two patients, while surgical correlation was possible in 14 patients,
MRA permitted classification of the level of aortic occlusion as juxtarena
l (n = 8), infrarenal, and cranial to the origin of the inferior mesenteric
artery (IMA; n = 11), and infrarenal but caudad to the IMA (n = 5), Extraa
natomical grafts were displayed to similar advantage as collateral parietal
and visceral pathways. Contrast-enhanced 3D MRA thus appears to be well su
ited for assessment of patients with suspected Leriche syndrome. (C) 2000 W
