Incidentally Found Double Aortic Arch While Treating Posterior Inferior Cerebellar Artery Aneurysm: Conversion from Femoral to Radial Artery Access

Abstract

Background: Asymptomatic double aortic arches are a unique occurrence.

Case description: An incidental finding of a double aortic arch in an elderly male was discovered during workup of a transient ischemic attack. The following case presentation details an effective treatment approach in cerebrovascular stenting in a patient with variant aortic arch anatomy. The initial diagnostic cerebral angiogram was performed via transfemoral approach and was quite challenging.

Conclusions: Faced with challenging anatomy, the radial artery approach is a viable option when navigating into the cerebrovascular anatomy for stenting when proximal variants such as a double aortic arch are identified.
