A bovine aortic arch is the most common variant of aortic arch branching in humans with a frequency ranged from 15% to 27%(1-2).it will be considered as a risk factor for aortopathy as anevrysm and dissection.
Methods: We report two cases with association of bovine aortic arch and aortopathy.
Results: in both cases the discovery of the anomaly of the aortic arch was fortuitous
Conclusion: A bovine aortic arch is frequent in patients with thoracic aortic disease than in the general population with a rapid evolution on the diameter of the aorta witch expose patient to more complications as anevrysm,rupture and dissection.It will be considered as a risk factor for aortopaty.
