A 59-year-old man with critical claudication underwent left femoro-anterior bypass grafting, which was uneventful. The graft was tunneled medially across the knee, then anterior to the tibia. His symptoms recurred 1 year later and he was found to have critical stenosis of the vein graft just proximal to the anterior tibial arterial anastomosis. This was treated with scaffolded balloon angioplasty and implantation of a coronary, zotarolimus-eluting balloon-expandable stent, which was also uneventful. However, his claudication again recurred 1 year later. Diagnostic angiography revealed crush, deformation and restenosis of the balloon-expandable stent requiring surgical revision of the bypass graft.

一名59岁的严重跛行男子接受了左股骨前旁路移植术,手术顺利。移植物在膝盖内侧穿过隧道,然后在胫骨前。一年后,他的症状复发,发现他在胫骨前动脉吻合术附近有严重的静脉移植物狭窄。用支架球囊血管成形术和冠状动脉zotarolimus洗脱球囊扩张支架进行治疗,这也很顺利。然而,他的跛行在1年后再次复发。诊断性血管造影显示球囊扩张支架的挤压,变形和再狭窄,需要手术修复旁路移植物。
