We report a left circumflex coronary aneurysm associated with separated left main coronary trunks (LMT). A 66-year-old man was admitted to our hospital for further examination of dyspnea on effort. He has been performed maintenance hemodialysis since 1999 for chronic renal failure. Coronary angiography and multislice spiral computed tomography (CT) revealed an unusual coronary anatomic variance in which separate origins of the left anterior descending (LAD) and left circumflex (LCx) coronary arteries arose from the left coronary aortic sinus. Furthermore, these images of the LCx revealed an aneurysm 2 cm in diameter and 99% stenosis at the proximal of side of the aneurysm. Under cardioplegic arrest, the aneurysm was ligated and coronary artery bypass grafting (left thoracic artery to posterolateral branch) was performed. The patient was discharged at the 20th postoperative day without any complication.
我们报告一例与左冠状动脉主干分离相关的左旋支冠状动脉瘤。一名66岁男性因劳力性呼吸困难入院进一步检查。自1999年起，他因慢性肾衰竭接受维持性血液透析治疗。冠状动脉造影和多层螺旋计算机断层扫描（CT）显示了一种不寻常的冠状动脉解剖变异，即左前降支（LAD）和左旋支（LCx）冠状动脉分别起源于左冠状动脉主动脉窦。此外，LCx的这些图像显示一个直径2厘米的动脉瘤，且在动脉瘤近端一侧有99%的狭窄。在心脏停搏下，结扎动脉瘤并进行冠状动脉旁路移植术（左胸廓内动脉至后外侧分支）。患者术后第20天出院，无任何并发症。
