ACUTE HYPERTENSION FOLLOWING DISSECTION O F A RENAL-ARTERY ANEURYSM

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.
