e0672 Treatment of atherosclerotic renal artery stenosis involving renal artery bifurcations

Objective To investigate the efficacy of kissing stent or kissing balloon technique for renal artery bifurcation with atherosclerotic renal artery stenosis. Methods There were five patients included, who were with atherosclerotic renal artery stenosis involving renal artery bifurcation. Results The reference vascular diameter of main renal artery was 5.6±0.4 mm. The reference vascular diameter of renal artery distal to bifurcation were 3.4±0.4 mm and 3.6±0.5 mm. Kissing balloon technique was used in three patients with obvious residual stenosis, and kissing stent technique was used in two patients without obvious residual stenosis. Blood pressure was lowered in two patients, unchanged in three patients. Serum creatine was lowered in one patient. Conclusion As for angiographic residual stenosis, it seems that kissing stent technique is more efficacious than kissing balloon technique.
