Rinkel GJ, et al. Intradural VA was identified for proximal control. Figure 1: posterior fossa vascular territories Figure 1: posterior fossa vascular territories. The fifth segment p5 starts where the PICA extends out from the fissure between the tonsil, vermis, and cerebellar hemisphere. It often happens that the bifurcation of the PICA occurs at this fifth segment; the lateral trunk will supply the tonsil and cerebral surface, while the medial trunk will supply the vermis. Advertisement Hide. For more distally positioned aneurysms, surgical access may be achieved using a telovelar approach Figs.
The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery.
Surgery of Posterior Inferior Cerebellar Artery (PICA) Aneurysm SpringerLink
It is one of the three main arteries that supply blood to the cerebellum. Supply. It has a variable territory depending on the size of the AICA (AICA-PICA dominance).
Typically it supplies: posteroinferior. The posterior inferior cerebellar artery (PICA) is the vessel that perfuses the lateral. a large PICA may supply most of the inferior surface of the cerebellum, and.

Video: Pica posterior inferior cerebellar artery supplies Wallenberg syndrome , Lateral medullary syndrome - posterior inferior cerebellar artery syndrome
The medial branch of the posterior inferior cerebellar artery supplies the medial part of the cerebellar hemisphere and the inferior vermis, while the lateral branch supplies the inferior cerebellar surface and anastomoses with the anterior inferior and superior cerebellar arteries.
It causes sensory, muscular dysfunction in the trunk and extremities on the opposite side of the occluded artery. The contralateral shoulder is pushed forward anteriorly, and there is mild inferior traction of the shoulder with tape.
Posterior inferior cerebellar artery Radiology Reference Article
The vertex of the head is tilted slightly toward the ground, and there is also a slight lateral rotation of the head toward the ground.
Posterior inferior cerebellar artery
The posterior inferior cerebellar artery (or PICA) is an artery that inferior cerebellar artery may cause an infarction (loss of blood supply) of the.
Practical neuroangiography. The PICA itself is usually of a small caliber, and aneurysms on it with a wide neck create a difficult situation with respect to clipping the aneurysm and preserving the PICA. The Cerebrospinal fluid needs to be released slowly so the brain is relaxed, and everything must be done under a microscopic view.
Cases and figures. It is an end-to-side anastomosis.

Blockage of the posterior inferior cerebellar artery can result in a type of stroke called lateral medullary syndrome. Severe occlusion of this artery or to vertebral arteries could lead to Horner's Syndrome as well.
