Posterior inferior cerebellar artery

The artery posterior inferior cerebellar artery (Latin for " lower rear cerebellar artery ."; Clinic in the jargon as PICA, posterior inferior cerebellar artery after engl ) is a paired arterial blood vessel and one of the vessels supplying the brain. Normally, it springs from the vertebral arteries ( arteries and vertebral ) shortly before its confluence to the basilar artery as their caliber strongest branch, circled the medulla oblongata (the " spinal cord extension " ) rearward toward the cerebellum and occurs between the X and the XI. Cranial nerves pass. In addition to the supply of most of the inferior cerebellar hemispheres and the lower worm smaller side branches are oblongata responsible for the perfusion of the posterior and lateral medulla.

History and size of the posterior inferior cerebellar artery subject to a pronounced variability. In about 10% of cases it emerges directly from the basilar artery.

An occlusion of the posterior inferior cerebellar artery leads to a cerebellar infarction and damage to the dorsolateral medulla oblongata to a complex and variable clinical picture, the Wallenberg syndrome.
