No data are available on the long-term outcome of coronary-coronary venous bypass grafting. We describe a case in which we successfully stented a discrete, critical stenosis of a coronary-coronary venous graft that had been placed 19 years earlier to minimize manipulation of a severely calcified ascending aorta. Coronary-coronary bypass grafting should be considered in cases involving severe aortic calcification, in situ grafts of inadequate length, and stenosed or occluded subclavian arteries. Such a bypass can be performed with either saphenous vein or arterial conduits, and it provides a flow rate similar to that of aortocoronary bypass. This option could be borne in mind as a 2nd-choice technique for the durable restoration of coronary blood flow in selected cases.
目前尚无关于冠状动脉-冠状静脉搭桥术长期预后的数据。我们描述了一例病例，在该病例中，我们成功地对一根19年前植入的冠状动脉-冠状静脉移植物的局限性严重狭窄病变进行了支架置入，以尽量减少对严重钙化的升主动脉的操作。在涉及严重主动脉钙化、原位移植物长度不足以及锁骨下动脉狭窄或闭塞的病例中，应考虑冠状动脉-冠状静脉搭桥术。这种搭桥术可以使用大隐静脉或动脉管道进行，其提供的血流量与主动脉冠状动脉搭桥术相似。在某些特定病例中，作为持久恢复冠状动脉血流的第二选择技术时，可以考虑这一方案。
