Superior cerebellar artery
Within the brain, the superior cerebellar artery branches off from the basilar artery. This occurs just below the posterior cerebellar artery, which forms the base of the cerebral arterial circle centrally located in the brain. Also, the artery goes around the cerebral peduncle and branches into smaller vessels. This artery delivers oxygenated blood to the superior part of the cerebellum and some locations within the midbrain. Also, this artery should not be confused with the superior cerbellar veins, which transit deoxygenated blood away from the brain and to the heart and lungs. Laterally, the superior cerebellar artery passes the ocular nerve. In addition, the artery is known to cause problems for another nerve. If it compresses the trigeminal nerve, a condition called trigeminal neuralgia will result. Lancinating pain can occur and spread across the face. This sharp or cutting pain may not necessarily be confined to the site of compression. Treatments include a range of medications. Botox injection has been used, which in a low dose would paralyze the nerve.
