Artery of Percheron

Dr Yuranga Weerakkody and Dr Jeremy Jones et al.

The artery of Percheron is a rare variant of the posterior cerebral circulation.

The term is used to refer to a solitary arterial trunk that branches from one of the proximal segments of either posterior cerebral artery (PCA). It supplies blood to the paramedian thalami and the rostral midbrain bilaterally.
