Embolic control of hypertension caused by segmental renal artery stenosis

Abstract

Renovascular hypertension was controlled in a 15-year-old boy by total infarction of the renal parenchyma behind a segmental renal artery stenosis. Two separate embolizations were required to occlude the branches distal to the stenosis. Blood pressure did not return to normal until after the second procedure. This approach may be useful in patients with intrarenal arterial stenoses who would be difficult to approach operatively without sacrificing a significant portion of the kidney.
