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.
累及肾动脉开口处的肾动脉狭窄对球囊血管成形术的反应往往欠佳。在此情况下，通过支架置入可优化即刻及长期效果。偶尔，病变可能累及分支点处的动脉中段。我们报告一例分叉病变病例，尽管采用了双球囊技术，该病变对球囊血管成形术的反应仍较差。最终通过以“双吻”方式置入两枚可弯曲线圈支架，获得了极佳的血管造影结果。患者的高血压在一夜之间得到控制。在6个月的随访中，他未服用药物血压仍保持正常。再次肾血管造影也显示无再狭窄。
