A 68-year-old man developed unstable angina 12 years following coronary artery bypass surgery. Angiography revealed an extensive area of severe stenosis and diminished distal flow in a right coronary artery vein bypass graft. Given the high distal embolism rate associated with conventional catheter-based treatment of old degenerated vein grafts, the diseased area was "relined" with a composite autologous saphenous vein-covered stent. The procedure was performed using modifications of standard PTCA methods and resulted in a widely patent, smooth lumen. This initial case demonstrates that a degenerated saphenous vein graft can be successfully revascularized with an autologous saphenous vein-covered stent in an attempt to minimize the potential complications of standard catheter-based revascularization methods.
一名68岁男性在冠状动脉搭桥手术后12年出现不稳定型心绞痛。血管造影显示右冠状动脉静脉搭桥移植物中有大面积严重狭窄且远端血流减少。鉴于传统导管介入治疗陈旧性退化静脉移植物时远端栓塞率较高，病变区域采用自体大隐静脉覆盖支架进行“内衬”。该手术采用了标准经皮冠状动脉腔内血管成形术（PTCA）方法的改良方式，术后管腔广泛通畅且光滑。这例首例病例表明，对于退化的大隐静脉移植物，使用自体大隐静脉覆盖支架可成功实现血管再通，以尽量减少标准导管介入血管再通方法的潜在并发症。
