Study of the variations of superior cerebellar artery in human cadavers

Vertebrobasilar system and its branches constitute the posterior circulation of the brain. The anatomy of the posterior circulation is very complex and is subjected to variations. 1 Superior Cerebellar Arteries (SCAs) are the most consistent branches arising from the basilar artery just below or at the level of its bifurcation. It supplies some portion of the midbrain, the superior surface of the cerebellar hemispheres, the superior vermis, deep cerebellar white matter and dentate nuclei. Different variations like duplication, triplication, and unusual origin have been reported in the western literature. 2 Aneurysms and stroke are the most common form of cerebrovascular diseases affecting mankind with a high degree of morbidity and mortality. The presence of arterial variations can be one of the factors attributed to aneurysms and thrombus formation leading to cerebellar infarcts.
