We present a case of a patient who experienced recurrent angina 15 months after coronary bypass surgery. A single lesion distal to a graft anastomosis was identified in the posterolateral coronary artery. There were two severe angulations, each greater than 90 degrees proximal to the lesion, with access possible only through the saphenous vein graft to the posterior descending artery. For ultimate success, such challenging anatomy required a combination of an array of guidewires, secondary support catheters, and a deflecting balloon.
我们报告一例患者，该患者在冠状动脉搭桥手术后15个月出现复发性心绞痛。在后外侧冠状动脉中发现移植吻合口远端有单个病变。病变近端有两个严重的成角，每个成角大于90度，只能通过大隐静脉移植到后降支动脉进行介入。为了最终成功，这种具有挑战性的解剖结构需要一系列导丝、辅助支撑导管和偏转球囊的组合。
