A percutaneous intra-arterial technique for producing renal artery stenosis.

A technique for creating an intra-arterial renal artery stenosis in the dog by a percutaneous approach is described. The effect of such a stenosis is evaluated with angiography, renal blood flow measurements, arterial blood pressure determinations and kidney histology. It is concluded that the method is applicable in studies on renal artery stenosis with the advantage of producing a progressive stenosis without any exploration of the kidney.
