Stenting of a renal artery bifurcation stenosis.
Renal artery stenosis involving the renal artery ostium often responds suboptimally to balloon angioplasty. In this context, immediate and long-term results can be optimized by stenting. Occasionally, lesions may involve the midartery segment at a branch point. We report a case of a bifurcation lesion which responded poorly to balloon angioplasty despite the kissing balloon technique. Excellent angiographic result was finally achieved by deploying two flexible coil stents in a "kissing" fashion. The patient's hypertension came under control overnight. At 6-month follow up, he remained normotensive on no medication. Repeat renal angiogram also showed no restenosis.
