The following are central branches of the PCA, also known as perforating branches: Thalamoperforating and thalamogeniculate or postero-medial ganglionic branches: a group of small arteries which arise at the commencement of the posterior cerebral artery: these, with similar branches from the posterior communicating, pierce the posterior perforated substance, and supply the medial surfaces of ...
The PCA begins as a continuation of the posterior communicating artery in 70-90% of fetuses with the remainder of PCAs having a basilar origin. The fetal carotid origin of the PCA usually regresses as the vertebral and basilar arteries become dominant and it finds a new origin in the basilar artery.
The leptomeningeal collateral circulation (also known as leptomeningeal anastomoses or pial collaterals) is a network of small blood vessels in the brain that connects branches of the middle, anterior and posterior cerebral arteries (MCA, ACA, and PCA), [1] with variation in its precise anatomy between individuals. [2]
Posterior cerebral artery syndrome is a condition whereby the blood supply from the posterior cerebral artery (PCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the occipital lobe, the inferomedial temporal lobe, a large portion of the thalamus, and the upper brainstem and midbrain.

The Canon of Medicine (c. 1000) - Described by Sir William Osler as a "medical bible" and "the most famous medical textbook ever written". [19] The Canon of Medicine introduced the concept of a syndrome as an aid to diagnosis , and it laid out an essential framework for a clinical trial . [ 20 ]
The anterolateral central arteries or lenticulostriate arteries [3] (also anterolateral perforating arteries, anterolateral ganglionic arteries, striate arteries, or lateral striate arteries; latin aa. centrales anterolaterales, [4] or aa. lenticulostriatae [4]) are a group of small arteries mostly arising from (the initial M1 part of) the middle cerebral artery that enter the brain through ...
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 .
