Vertebrobasilarterial network after catheterization of the left subclavian artery (angiography)

Subsequent angiographic images of the vertebrobasilar arterial network after catheterization of the left subclavian artery and contrast media instillation. Blood flows through the left vertebral artery (A), partly supplies the basilar artery (B, C), but preferentially runs back through the right vertebral artery towards the right subclavian artery (B, C, and D) depicting a crossed subclavian-vertebral steal syndrome. Arrow: left vertebral artery. (Source: Filis K, Toufektzian L, Sigala F, et al. Right subclavian double steal syndrome: a case report. J Med Case Rep 2008;2:392.
