The situation of the arteria spinalis anterior. This unpaired structure is particular amongst the cerebral arteries, for the reason that it is a quite rare unpaired artery, together with the arteria basilaris and the arteria communicans anterior. Indeed, the system of cerebral arteries is predominantly a double system with a few important anastomoses insuring a beneficial redundancy. The arteria spinalis anterior is formed by the junction of two branches of the left and right vertebral arteries at the level of the cranium, then the artery descends on the anterior face of the spinal cord, having a number of anastomoses with lateral arteries. It terminates with the spinal cord at the level of L2.An unpaired artery cannot be a branch of two distinct arteries. Therefore, the arteria spinalis anterior is considered to be part of the systema vertebrobasilare. |
