Information about Basilar Artery
| Artery: | |
|---|---|
| The basilar artery (middle of figure) arises from the vertebral arteries and terminates when it bifurcates in the left and right posterior cerebral arteries. | |
| Latin | arteria basilaris |
| subject #148 580 | |
| Supplies | superior and inferior aspects of the cerebellum pons |
| Source | vertebral arteries |
| Branches | anterior inferior cerebellar artery pontine branches |
| MeSH | Basilar+Artery |
Course
It arises from the confluence of the two vertebral arteries at the junction between the medulla oblongata and the pons.It ascends in the central gutter (sulcus basilaris) inferior to the pons and divides into the posterior cerebral arteries and the superior cerebellar artery just inferior to the pituitary stalk.
From the basilar artery arises the anterior inferior cerebellar artery (supplying the superior and inferior aspects of the cerebellum), as well as smaller branches for the supply of the pons (the pontine branches).
Pathology
Thrombosis of the basilar artery can be life-threatening, as it leads to hypoxia and ischemia of the brainstem.Poor prognoses are common and these can include paralysis of all extremities, heavy disturbances in sensation, difficulty in swallowing and difficulty in respiration.
Basilar artery thrombosis is the most common cause of locked-in syndrome.[1]
