Diagnostic Ultrasound - Abdomen and Pelvis

Renal Artery Stenosis
(Left) Oblique color Doppler
ultrasound shows a normal
right renal artery, which
consistently arises from the
anterolateral aspect of the
aorta and travels posterior
to the IVC and left renal vein
st. (Right) Oblique color
Doppler ultrasound shows the
origin of the left renal artery
ſt, which varies from
anterolateral to
posterolateral, but always lies
posterior to the left renal vein
st.
Diagnoses: Urinary Tract
(Left) Spectral Doppler
ultrasound of a downstream
(arcuate) artery demonstrates
a slow upstroke and RI <
0.5 in a transplant kidney with
renal artery stenosis. (Right)
Left common iliac artery
injection shows a high-grade
stenosis of the transplant
renal artery , which arises
from the external iliac. This
was angioplastied, with some
improvement in transplant
function.
(Left) Coronal MIP in a 30-
year-old woman with
fibromuscular dysplasia shows
an irregular corrugated or
beaded appearance of the mid
right renal artery , with
relative sparing of the ostium
and proximal portion of artery
. This patient's aneurysmal
SMA is also seen in the image
. (Right) In another patient
with FMD, oblique DSA shows
a series of ridges in the distal
right renal artery . This is a
middle-aged woman with
poorly controlled
hypertension. FMD is more
common on the right, but is
often bilateral.
