Ischemic nephropathy: Detection and therapeutic intervention

Various therapeutic options are reviewed, with emphasis on percutaneous transluminal renal angiography plus stent as the first indication. Even though initial reports were contradictory, several meta-analyses have concluded that better blood pressure control and renal function improvement are achieved with percutaneous transluminal renal angiography plus stent than with conventional medical therapy. Surgical revascularization is preferable in patients with severe aorto-iliac pathology and renal artery ostium complete thrombosis. The risks and benefits of these procedures must be evaluated on an individual basis.
