Tandem stenting of crossed renal arteries with ostial stenosis.

Ostial stenosis of renal arteries has been shown to respond favorably to stenting. Heterogeneity of renal artery anatomy is very common and often increases the technical difficulty of percutaneous treatment of stenotic lesions. We present the case of a 69-year-old man with severe hypertension who had 2 right renal arteries, both of which had ostial stenosis. We treated these stenoses with simultaneous stenting of both renal ostia. Since the procedure, the patient has had significantly improved control of his hypertension.
