Abstract
BACKGROUND: The branch anatomy of the aortic arch varies widely between individuals. These are likely due to alterations in the development of aortic arch arteries during the embryonic period. The purpose of this study is to determine the frequency of the aortic arch branch variations in the local population and provide useful data to intervention radiologists, neck and thoracic surgeons. METHODS: In this study, branching pattern of the aortic arch in 226 patients was retrospectively evaluated by MR angiography. MRA performed on a high field 3 Tesla MRI scanner using 3D flash sequence. RESULTS: The normal aortic arch branching pattern was observed in 192 patients (84.9%). Also, three variations of the aortic arch branching pattern were observed. The aortic arch in 12.4% of the patients had two arterial branches. In 0.9% of cases, the left vertebral artery originated directly from the aortic arch. In 1.8% of cases, the right subclavian artery originated as the fourth aortic arch branch. CONCLUSION: Although the number of cases with aortic arch branches variation in our study is similar to other studies, the Bovine aortic arch variation is more common than other variations of aortic arch branches.
