BACKGROUND: Aneurysm of the renal artery is an uncommon discovery at a
rteriography performed as part of a hypertension work-up. CASE REPORTS
: We observed acute hypertension following dissection of a renal arter
y aneurysm which led to circulating channel stenosis. After surgical c
orrection of the lesion, arterial pressures returned to normal. DISCUS
SION: Most cases of renal artery aneurysm do not cause hypertension. I
n such cases, the high blood pressure is idioptahic or related to fibr
odysplastic stenosis of the renal artery often associated with aneurys
m formation. In rare cases with obstructive complications alone an ane
urysm may lead to acute hypertension either after dissection as in our
case or after thrombus formation. Surgery is generally required.
