Views Read Edit View history. The anterior inferior cerebellar artery AICA is one of three pairs of arteries that supplies blood to the cerebellum. It has a variable course, passing backward to be distributed to the anterior part of the undersurface of the cerebellum, anastomosing with both the posterior inferior cerebellar PICA branch of the vertebral artery and the superior cerebellar artery. The amount of tissue supplied by the AICA is variable, depending upon whether the PICA is more or less dominant, but usually includes the anteroinferior surface of anteorinferior cerebellum, the flocculus, middle cerebellar peduncle and inferolateral portion of the pons.
