In 16 patients who underwent endarterectomy of the left anterior descending (LAD) coronary artery combined with saphenous vein bypass grafting between Aug. 1, 1976 and July 31, 1978, the results of preoperative and postoperative angiography were comparable. Most patients had obstruction or severe stenosis of the proximal LAD coronary artery together with a poor runoff as demonstrated angiographically. Eighteen vein grafts were placed in the LAD artery and 15 (83%) were satisfactorily patent. Six of 18 grafted arterial segments became occluded distal to the site of graft insertion, but in most cases there was sufficient proximal runoff to maintain graft patency. In this study intraoperative measurements of graft flow were predictive of graft or distal vessel patency, or both. Careful postoperative assessment of the results of this technique seems warranted.
在1976年8月1日至1978年7月31日期间接受左前降支（LAD）冠状动脉内膜切除术并联合大隐静脉旁路移植术的16例患者中，术前和术后血管造影结果具有可比性。血管造影显示，大多数患者的LAD冠状动脉近端存在阻塞或严重狭窄，且血流灌注不佳。18条静脉移植物被植入LAD动脉，其中15条（83%）通畅良好。18个移植动脉段中有6个在移植部位远端闭塞，但在大多数情况下，近端有足够的血流灌注以维持移植物通畅。在本研究中，术中对移植物血流的测量可预测移植物或远端血管的通畅情况，或两者兼而有之。似乎有必要对该技术的结果进行仔细的术后评估。
