Fig. 1. —80-year-old man with type A, subtype b abdominal aortic
aneurysm.
D and E, Maximum-intensity-projection reconstructions in
oblique craniocaudal view from all data sets (D) and at level of renal
arteries (E) reveal bilateral renal artery stenosis (arrows,
D). Note small accessory renal artery of left kidney is seen in
E (small arrows) but not in D.

Fig. 1. —80-year-old man with type A, subtype b abdominal aortic
aneurysm.
A and B, Axial transverse CT scans at level of infrarenal
aorta (A) and iliac arteries (B) show 45-mm aneurysm extending
into common iliac arteries.

Fig. 1. —80-year-old man with type A, subtype b abdominal aortic
aneurysm.
C, Digital subtraction angiogram shows no evidence of aneurysm in
iliac arteries. Aneurysms were under-estimated because angiography reveals
only contrast-enhanced lumen.

Fig. 1. —80-year-old man with type A, subtype b abdominal aortic
aneurysm.
F, Aortogram shows bilateral renal artery stenoses
(arrowheads). Note difficulty of localizing accessory left renal
artery and left renal artery stenosis.

Fig. 2 —78-year-old man with type B, subtype b abdominal aortic
aneurysm.
A and B, Maximum-intensity-projection reconstructions from CT
data show 55-mm aortic aneurysm at level of inferior mesenteric artery
(arrow, A) and accessory right renal artery originating from
abdominal aneurysm (arrow, B).

and celiomesenteric occlusive disease.
B, Axial CT scan at level of superior mesenteric artery reveals
stenosis quantified as grade 2 (75% reduction in diameter)
(arrow).

Fig. 3. —55-year-old man with abdominal aortic aneurysm (type A, subtype b)
and celiomesenteric occlusive disease.
C, Lateral digital aortogram shows moderate (grade 1) stenosis of
superior mesenteric artery (arrow). This stenosis was probably
underestimated because it was a lateral eccentric plaque that is difficult to
assess in lateral projection. Patient also had stenosis of celiac trunk well
seen on CT.

Fig. 4. —59-year-old man with type A, subtype a abdominal aortic aneurysm and
severe peripheral and visceral occlusive lesions.
A, Maximum-intensity-projection reconstruction in anterior view of
abdominal aorta and iliac arteries shows occlusion of superior mesenteric
artery at origin and occlusion of common and external right iliac arteries.
Note hypertrophied inferior mesenteric artery (thin arrows) and
arterial supply of right common femoral artery via epigastric artery
(thick arrows). Denser calcifications seen in left iliac and femoral
arteries obscure arterial lumen analysis.

Fig. 5. —75-year-old man with type A, subtype b abdominal aortic aneurysm.
Maximum-intensity-projection reconstruction of abdominal aorta and iliofemoral
arteries shows 50-mm infrarenal abdominal aneurysm extending to aortic
bifurcation. Tortuosity of iliac arteries is well revealed.
