Between November 1977 and September 1978, early post-operative angiography was performed in 50 of 53 consecutive patients undergoing coronary artery bypass surgery. An average of 2.4 grafts per patient were applied. The overall patency rate was 82% and was not affected by the degree of proximal native vessel stenosis. Grafts to circumflex marginal vessels had a significantly lower (P < 0.05) patency rate (72%) than grafts to the left anterior descending (84%) and its diagonal branches (85%), or to the right coronary artery (90%). Ten single grafts were applied and all were patent. Forty-nine of the 50 patients had at least one patent graft. Fifty-three per cent of the grafts were considered of excellent quality and 25% patent but of fair quality only. There was a 100% patency rate for vessels of 2 mm diameter or more, which is significantly better (P < 0.01) than for vessels of 1-2 mm diameter (78%) or for vessels of less than 1 mm diameter (50%). There was a suggestion of a lower patency rate (74%) for vessels with evidence of distal disease, compared with vessels without such disease (85%). An assessment of the overall quality of the recipient vessel was made, taking both diameter and disease into account. This showed improved results for better quality vessels in terms of graft patency (P < 0.1) and graft quality (P < 0.05).
1977年11月至1978年9月期间，对53例连续接受冠状动脉搭桥手术的患者中的50例进行了术后早期血管造影。每位患者平均植入2.4根移植血管。总体通畅率为82%，不受近端自身血管狭窄程度的影响。植入到回旋支边缘血管的移植血管通畅率（72%）明显低于植入到左前降支（84%）及其对角支（85%）或右冠状动脉（90%）的移植血管（P<0.05）。共植入10根单支移植血管，均保持通畅。50例患者中有49例至少有一根移植血管通畅。53%的移植血管被认为质量优良，25%的移植血管通畅但质量一般。直径2毫米及以上血管的通畅率为100%，明显优于直径1 - 2毫米的血管（78%）或直径小于1毫米的血管（50%）（P<0.01）。有远端病变证据的血管通畅率（74%）似乎低于无此类病变的血管（85%）。综合考虑血管直径和病变情况，对受体血管的整体质量进行了评估。结果显示，质量较好的血管在移植血管通畅率（P<0.1）和移植血管质量（P<0.05）方面有更好的结果。
