With increasing use of transradial access (TRA) to perform coronary angiography, arterial anomalies of the upper extremity are more frequently encountered. We describe a patient with an aberrant right subclavian artery (RSCA) originating as the last major branch of the aortic arch, which eventually led to failure of the transradial approach. Subsequent arch aortography revealed an associated common carotid trunk. The combination of both anomalies is a rare finding and may be associated with a number of other arterial and/or mediastinal organ anomalies.
随着经桡动脉途径（TRA）用于冠状动脉造影的情况日益增多，上肢动脉异常的情况也更频繁地被遇到。我们描述了一名患者，其右锁骨下动脉（RSCA）走行异常，起源于主动脉弓的最后一个主要分支，最终导致经桡动脉途径失败。随后的主动脉弓造影显示存在一个合并的共同颈动脉干。这两种异常的组合是一种罕见的发现，可能与许多其他动脉和/或纵隔器官异常有关。
