Comment: The vertebrobasilar circulation supplies posterior
circulation to the brain stem and cerebellum, part of the
diencephalon, the occipital lobe, and inferior part of the temporal
lobe. The vertebral arteries and basilar artery give rise to paramedian,
short circumferential, and long circumferential arteries that supply
wedge-shaped territories or specific medial and lateral territories
of the brain stem and cerebellum with blood. An occlusion may
lead to damage of cranial nerve and brain stem nuclei, as well as
long tracts, leading to highly predictable but unusual clusters of
symptoms such as the lateral medullary syndrome. The middle and
anterior cerebral arteries give rise to specific named branches that
supply blood to specific regions of the hemisphere. Disruption can
result in symptoms specific to the role subserved by the cortical or
subcortical regions affected.
