Two-stent strategy for renal artery stenosis with bifurcation lesion.
Renal artery stenosis (RAS) with a bifurcation lesion is a challenge for interventional therapy. The aim of this study is to summarize our experience in RAS with a bifurcation lesion. Five patients with RAS involving bifurcation lesion are described. In cases 1 to 3, a single-stent strategy was first adopted. However, these three patients were converted to a two-stent strategy for bailout stent implantation in the side branches. In cases 4 and 5, a simultaneous kissing stent technique was performed. Angiography showed that the reference vascular diameter of the main branch was much larger than those of the side branches. Although obvious residual stenosis existed in cases 1 to 3 after stent implantation, no obvious residual stenosis was seen in cases 4 and 5. Renal artery duplex sonography was performed in cases 1 through 5 at 6, 7, 7, 8, and 6 months, respectively, after the procedures. No evidence of restenosis or occlusion was seen. In conclusion, stent implantation with the simultaneous kissing stent technique may result in more simple and more satisfactory immediate angiographic results.
