RESUMO
Synchronous spontaneous triple coronary artery dissection with Takayasu arteritis has not been previously reported in the literature. We describe the case of a young man with acute inferior wall myocardial infarction secondary to triple-vessel coronary artery dissection. Takayasu arteritis was diagnosed upon further investigation. (Level of Difficulty: Intermediate.).
RESUMO
PURPOSE: Variance of aortic arch branches are clinically significant as they are encountered in multiple endovascular treatments. The knowledge of different variants is crucial to perform successful vascular interventions. METHODS: We report a novel anatomical variant of aortic arch found on contrast-enhanced computed tomography scan during a workup of cervical lymphadenopathy. RESULTS: The CT neck revealed a bovine aortic arch with an aberrant origin of bilateral vertebral arteries from the aortic arch. The right vertebral artery arose between the bovine trunk and the left subclavian artery, while the left vertebral artery was present distal to the left subclavian artery. CONCLUSION: This article sheds light on the potential clinical significance of these various types of aortic arch branches. Knowing the exact type of variant is particularly important in patient undergoing management involving carotid and surrounding vessels.
