摘要
目的 分析少见的先天性冠状动脉变异的冠状动脉造影的表现,探讨冠状动脉造影的诊断价值。方法 收集1997-1999年410例冠状动脉造影中的先天性冠状动脉变异共16例,其中壁冠状动脉8例,冠状动脉瘘6例及先天性右冠状动脉缺如2例。冠状动脉造影,动态下观察,并进行必要的测量。结果 8例壁冠状动脉均表现为收缩期狭窄,1级3例,2级4例,3级1例狭窄段长度17.2mm,其中3级1例行冠状动脉旁路移植术。6例冠状动脉瘘,5例源自左冠状动脉,1例源自双侧冠状动脉,2例引流入肺动脉于,4例引流入右心室。2例右冠状动脉缺如,经冠状动脉造影及主动脉造影证实。结论 冠状动脉造影是诊断少见先天性冠状动脉变异的重要手段,动态下观察是发现病变的关键。
Purpose To analyze the features of congenital variation of coronary artery by coronary artery angiography. Methods Among 410 cases underwent coronary artery angiography (from 1997 to 1999), 16 cases of congenital variation of coronary artery lackage(2 cases)were studied retrospectvely. Measuring the size on the coronary artery angiography were done by dynamic observation. Resultes 8 cases of myocardial bridge were found on the systolic narrowing( milking effect), grade one(3 cases), grade two(4 cases), grade three(1 case). The average extent of narrowing was 17. 2mm. Among 6 cases of coronary fistula, the localization at the left coronary artery is 5 cases, both coronary 1 case, and right coronary lackage 2 cases. Conclusions coronary artery angiography is the diagnostic base of congenital variation of coronary artery, the key of diagnosis is dynamic obse-vation.
