Posterior inferior cerebellar artery
Blood vessels · Latin: Arteria cerebelli inferior posterior
The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery.
It is one of the three main arteries that supply blood to the cerebellum, a part of the brain.
Blockage of the posterior inferior cerebellar artery can result in a type of stroke called lateral medullary syndrome.
