While coronary arteries of anomalous origin are uncommon, some forms seem to be predisposed to atherosclerosis. Very few cases of percutaneous transluminal coronary angioplasty (PTCA) in anomalous arteries have been reported. We report a case of successful PTCA of the left anterior descending artery through an anomalous left main coronary artery originating from the right aortic sinus in a 65-year-old man with unstable angina. PTCA was performed using an 8 F 3.5 cm right Judkins guiding catheter to dilate a discrete 90% stenosis of the left anterior descending artery. After PTCA, the patient became symptom free. Using the proper guiding catheter, PTCA can be performed in coronary arteries of anomalous origin with excellent results.
虽然冠状动脉起源异常并不常见，但某些类型似乎易患动脉粥样硬化。经皮腔内冠状动脉成形术（PTCA）应用于异常动脉的病例报道极少。我们报告一例65岁不稳定型心绞痛男性患者，其左冠状动脉主干起源于右主动脉窦，通过该异常左冠状动脉主干成功对左前降支进行了PTCA。使用8F 3.5cm右Judkins引导导管进行PTCA，以扩张左前降支一处孤立的90%狭窄病变。PTCA术后，患者症状消失。使用合适的引导导管，可在冠状动脉起源异常的情况下进行PTCA，且效果良好。
