Abstract

Cases of percutaneous transluminal renal angioplasty for renal artery stenosis are increasing. However, percutaneous transluminal renal angioplasty with stenting for stenotic venous bypass grafts has never been reported. Herein, the authors describe two cases of percutaneous transluminal renal angioplasty with stenting for a stenotic venous bypass graft. The patients in both cases had undergone bypass grafting using autologous saphenous veins, which were anastomosed directly to their abdominal aortas. We successfully conducted percutaneous transluminal renal angioplasty with stenting. One of the keys for technical success is an appropriate selection of guiding catheter compatible with postoperative nonanatomical vasculature, and the other is relatively high pressure dilation for venous stenosis.
