Angioplasty of degenerated saphenous vein grafts is not infrequently complicated by distal embolization of atheromatous debris. We describe an uncommon case in which balloon angioplasty of an old vein graft to a second diagonal branch of the left anterior descending coronary artery was followed by distal embolization. However, the embolization occurred in a retrograde fashion distal to the anastomotic site, resulting in occlusion of the upstream first diagonal branch. The reasons for its occurrence are discussed, together with suggestions for its recognition.
退化的大隐静脉移植物血管成形术常常并发动脉粥样硬化碎片的远端栓塞。我们描述了一个罕见病例，在对左前降支冠状动脉第二对角支的陈旧静脉移植物进行球囊血管成形术后发生了远端栓塞。然而，栓塞以逆行方式发生在吻合口远端，导致上游第一对角支闭塞。本文讨论了其发生原因，并提出了识别建议。
