Frequency and imaging findings of variations in human aortic arch anatomy based on multidetector computed tomography data.
The purpose of this study was to describe the frequency of the variations in the branching pattern of the aortic arch (AA) according to multidetector computed tomography (MDCT) imaging findings. MDCT images of 1136 consecutive patients who had undergone imaging of the chest were retrospectively examined. Eleven different branching patterns were observed. A left-sided AA with three major branches was seen in 74.4% of the patients. Bovine-type AA (21.1%) and independent origin of the left vertebral artery (3.7%) were the next two most common patterns.
