The splenial artery (or posterior pericallosal artery) arises most commonly from the parieto-occipital branch of the posterior cerebral artery. It represents an important potential collateral supply from the posterior to anterior cerebral arteries via the pericallosal artery. When a sizable direct anastomosis is present, it is referred to as a persistent limbic arch 4.
Variant anatomy
The splenial artery usually arises from the posterior parieto-occipital branch of the posterior cerebral artery (60% of cases). In a minority of cases, it arises from other regional arteries including 1-3:
calcarine artery: 10-15%
posterior temporal artery: 10%
P2 or P3 segments of PCA: 5% each
