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.
