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.

摘要

经皮腔内肾血管成形术治疗肾动脉狭窄的病例正在增加。然而，经皮腔内肾血管成形术联合支架置入治疗狭窄性静脉搭桥血管尚未见报道。在此，作者描述了两例经皮腔内肾血管成形术联合支架置入治疗狭窄性静脉搭桥血管的病例。两例患者均接受了使用自体大隐静脉的搭桥手术，大隐静脉直接与腹主动脉吻合。我们成功地进行了经皮腔内肾血管成形术联合支架置入。技术成功的关键之一是选择合适的与术后非解剖血管系统兼容的引导导管，另一个是对静脉狭窄进行相对较高压力的扩张。
