anterior spinal artery

The anterior spinal artery has a less efficient supply of blood and is therefore more susceptible to vascular disease.

Each hemicord has its own anterior spinal artery.

They can join the anterior spinal artery.

It is called anterior spinal artery syndrome.

They are also not only smaller in size but more numerous than the equivalent anterior spinal artery which they lie dorsal to.

The anterior portion of the spinal cord is supplied by the anterior spinal artery.

As the anterior spinal artery proceeds inferiorly, it receives branches originating mostly from the aorta.

The anterior spinal artery arises bilaterally as two small branches near the termination of the vertebral arteries.

This occurs when the disruption of the anterior spinal artery is at the level of the spinal cord.

At each cervical level, the vertebral artery sends branches to the surrounding musculature via anterior spinal arteries.

Due to the branches of the aorta that supply the anterior spinal artery, the most common causes are insufficiencies within the aorta.

The three longitudinal arteries are called the anterior spinal artery, and the right and left posterior spinal arteries.

In human anatomy, the anterior spinal artery is the blood vessel that supplies the anterior portion of the spinal cord.

Contrast this with medial medullary syndrome, when the anterior spinal artery is occluded at the level of the medulla oblongata.

The anterior spinal cord, which makes up 2/3 of the entire spinal cord, gets its blood supply from the anterior spinal artery.

Both the posterior and anterior spinal arteries run the entire length of the spinal cord and receive anastomotic (conjoined) vessels in many places.

The anterior cord syndrome: a lesion of the anterior horns and the anterolateral tracts, with a possible division of the anterior spinal artery.

Anterior spinal artery syndrome is necrosis of tissue in the anterior spinal artery or its branches.

Cervical malformations arise from the anterior spinal artery and lie within the cord, whereas thoracolumbar malformations can be internal, external or encompass both areas of the cord.

Anterior spinal artery: The anterior spinal artery supplies the whole medial part of the medulla oblongata.

Ischemia of the spinal cord is reduced blood flow to the spinal cord which is supplied by the anterior spinal artery and the paired posterior spinal arteries.

Ischemia or infarction of the spinal cord in the distribution of the anterior spinal artery, which supplies the ventral two-thirds of the spinal cord and Medulla.

It typically arises from a left posterior intercostal artery, which branches from the aorta, and supplies the lower two thirds of the spinal cord via the anterior spinal artery.

Acute disc herniation, cervical spondylosis, kyphoscoliosis, damage to the spinal column and neoplasia all could result in ischemia from anterior spinal artery occlusion leading to anterior cord syndrome.

This condition is usually associated with Atherosclerosis of the aorta and may result from dissection of an Aortic aneurysm or rarely dissection of the anterior spinal artery or systemic arteritis.
