Chronic Renal Artery Occlusion: Nephrectomy Versus Revascularization

Renal artery occlusion (RA-OCC) represents the final expression of anatomically progressive atherosclerotic renovascular occlusive disease. When a highgrade stenosis progresses to occlusion, the event may be clinically silent or previously controlled hypertension may worsen and serum creatinine levels may elevate.1 Given that as much as 35% of mild contralateral renal artery atherosclerotic lesions progress to sigChronic renal artery occlusion: Nephrectomy versus revascularization
