Posterior cerebral artery syndrome

From Wikipedia, the free encyclopedia


Posterior cerebral artery syndrome Classification and external resources
Outer surface of cerebral hemisphere, showing areas supplied by cerebral arteries. (Pink is region supplied by posterior cerebral artery.)
ICD-10	G 46.2
eMedicine	neuro/322
MeSH	D020762

Posterior cerebral artery syndrome is a condition where the blood supply from the posterior cerebral artery is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel.

Because this artery supplies the occipital lobe, this condition can be associated with visual defects.
