title: A rare anomaly of the aortic arch: aberrant right subclavian artery associated with common carotid trunk.
abstract: 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.
