We report a case of competitive blood flow in the left coronary circulation after saphenous vein bypass grafting that resulted in the apparent progression of a proximal stenosis to total occlusion at coronary angiography. Repeat angiography with careful attention to catheter position and adequate injection of contrast agent demonstrated the actual anatomy and showed that there was no postoperative change in the native coronary circulation. The true incidence of progression of proximal coronary disease after saphenous vein bypass surgery is unknown, and reported figures may be falsely elevated because of unrecognized competitive flow patterns simulating obstruction.
我们报告了一例隐静脉搭桥术后左冠状动脉循环中出现竞争性血流的病例，该病例在冠状动脉造影时显示近端狭窄明显进展至完全闭塞。重复造影时仔细注意导管位置并充分注射造影剂，显示了实际解剖结构，表明自身冠状动脉循环术后无变化。隐静脉搭桥术后近端冠状动脉疾病进展的真实发生率尚不清楚，且由于未识别出模拟阻塞的竞争性血流模式，报告的数字可能被错误抬高。
