摘要
分析19例患者闭塞冠状动脉(冠脉)的影象特点和球囊扩张治疗结果.发现16例并存非闭塞冠脉狭窄,其中12例表现为70%以上的重度狭窄.所有闭塞冠脉均有良好的侧支循环,左前降支和右冠脉闭塞均表现为对侧侧支循环,左旋支闭塞者3例为同侧侧支循环,1例为对侧侧支循环.13例闭塞血管经球羹扩张后再通,6例失败,其主要原因为导丝不能通过闭塞部位(5例)和球囊不能跨过闭塞部位(1例).
Ninteen patients with chronic total coronary artery occlusion were underwent an-giography and balloon angioplasty. It was found that 16 of them had also one or more non-occlu-sive artery,and 12 of them showed more than 70% stenosis. All of the occlusive artery had good collateral circulation. The distal vessels of the occlusion in left anterior descending (LAD) and right coronary artery (RC) were circulated with countralateral branch, and circumflex coronary artery (CX) was circulated with LAD (3 cases) or RC (1 case). 13 patients were recanalized in their occlusive vessels after balloon angioplasty, and another 6 patients were not recanalized because guidwires (5 cases)and balloon catheter (1 case) failed to pass through the occlusive part of the vessels.
