A case of coronary artery bypass grafting (CABG) for single coronary artery complicated by angina pectoris (AP) was reported. The patient was a 74-year-old male, complained of anginal discomforts. His single coronary artery originated in left coronary sinus, bifurcated to the left anterior descending artery (LAD) and the circumflex artery (CX), and then, an abnormal communicating branch, passing in front of the right ventricular outflow, was branched from the proximal region of LAD; it showed a route corresponding to the proximal region of the right coronary artery (RCA). The distal region of RCA and the posterior descending artery were angiographed in continuity from CX. Other findings included 75%-stenosis at LAD-#6 and 90%-stenosis at CX-#13. Using two saphenous vein grafts, CABG operation was carried out on those regions at LAD-#7 and distal CX corresponding to #3 normally. Postoperatively, anginal discomforts disappeared, and favorable results were obtained.
报道了一例单支冠状动脉合并心绞痛行冠状动脉旁路移植术（CABG）的病例。患者为74岁男性，主诉心绞痛不适。其单支冠状动脉起源于左冠状动脉窦，分为左前降支（LAD）和回旋支（CX），然后，一条异常的交通支从LAD近端区域分出，在右心室流出道前方走行，显示出与右冠状动脉（RCA）近端区域相对应的走行。RCA远端区域和后降支从CX连续进行血管造影。其他发现包括LAD-#6处75%狭窄和CX-#13处90%狭窄。使用两根大隐静脉移植物，在LAD-#7和正常对应于#3的CX远端区域进行了CABG手术。术后，心绞痛不适消失，获得了良好的效果。
