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 .
Three arteries supply blood to the cerebellum (Fig. 7): the superior cerebellar artery (SCA), anterior inferior cerebellar artery (AICA), and posterior inferior cerebellar artery (PICA). The SCA branches off the lateral portion of the basilar artery, just inferior to its bifurcation into the posterior cerebral artery. Here, it wraps posteriorly ...

The cerebellum is provided with blood from three paired major arteries: the superior cerebellar artery (SCA), the anterior inferior cerebellar artery (AICA), and the posterior inferior cerebellar artery (PICA). The SCA supplies the upper region of the cerebellum.
Within the cranium the two vertebral arteries fuse into the basilar artery. Posterior inferior cerebellar artery (PICA) Basilar artery: Supplies the midbrain, cerebellum, and usually branches into the posterior cerebral artery. Anterior inferior cerebellar artery (AICA) Pontine branches; Superior cerebellar artery (SCA) Posterior cerebral ...
The posterior spinal artery (dorsal spinal arteries) arises from the vertebral artery in 25% of humans or the posterior inferior cerebellar artery in 75% of humans, adjacent to the medulla oblongata. [citation needed] It is usually double, and spans the length of the spinal cord. It supplies the grey and white posterior columns of the spinal ...
The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain. The three main arteries are the: Anterior cerebral artery (ACA), which supplies blood to the medial portion of the brain, including the superior parts of the frontal and anterior parietal lobes [1]
