Thirty five patients, operated upon with an aorto-coronary by-pass graft to left anterior descending artery and to a major diagonal branch, were prospectively analysed. The patients were divided into two comparable groups, in whom a single graft technique and a sequential graft technique was used respectively. Flows through the by-passes were measured electromagnetically during the operation. Flow to left anterior descending artery was significantly higher through an isolated by-pass than through a sequential by-pass. Flow to diagonal branch showed no significant difference in the two groups. The resistance of the intramyocardial coronary bed of the left anterior descending artery was lower with single than with sequential by-pass technique, while no difference existed between the resistance of intramyocardial coronary bed of the diagonal branch with both techniques. Blood velocity was higher in single by-pass to the left anterior descending artery than in the peripheral segment of sequential vein graft directed to the anterior descending artery.
对35例行主动脉冠状动脉搭桥术，分别移植至左前降支和一支主要对角支的患者进行了前瞻性分析。患者被分为两个可比组，分别采用单支移植技术和序贯移植技术。术中通过电磁法测量搭桥血管的血流量。通过孤立搭桥至左前降支的血流量显著高于序贯搭桥。至对角支的血流量在两组中无显著差异。单支搭桥技术时左前降支心肌内冠状动脉床的阻力低于序贯搭桥技术，而两种技术下对角支心肌内冠状动脉床的阻力无差异。左前降支单支搭桥的血流速度高于序贯静脉搭桥至前降支外周段的血流速度。
