What is anterior spinal artery syndrome?
The anterior spinal artery syndrome refers to ischemic infarction of the spinal cord resulting from direct occlusion of the anterior spinal artery, artery of Adamkiewicz, or generalized hypoperfusion. It is associated with many other disease conditions or treatment complications.
What causes posterior cord syndrome?
Posterior cord syndrome occurs as a result of damage to the posterior columns of the spinal cord. Such damage can be caused by trauma to the spinal cord and damage to the protective myelin sheath that surrounds nerve fibers (i.e. demyelinating disorders).
Where do the posterior spinal arteries originate?
The two posterior spinal arteries originate directly from the vertebral arteries and are the primary blood supply to the posterior columns, dorsal grey matter, dorsal sensory columns – these arteries are often found to be discontinuous, and occasionally one artery will move across to supply the opposite side.
Who gets anterior cord syndrome?
The anterior spinal cord is at increased risk for infarction because it is supplied by the single anterior spinal artery and has little collateral circulation, unlike the posterior spinal cord which is supplied by two posterior spinal arteries….Anterior spinal artery syndrome.

What is the prognosis of posterior cord syndrome?
This syndrome carries a poor prognosis for functional improvement, with only a 10% to 20% chance of muscle recovery, and even in those with some recovery, there is poor muscle power and coordination (21). PCS is the least common of the SCI clinical syndromes, with an incidence of less than 1% (6).
How many anterior spinal arteries are there?
The spinal cord relies on 3 main arteries for vascular supply. The anterior spinal artery supplies the anterior two-thirds, and the 2 posterolateral spinal arteries supply the posterior third of the spinal cord. The anterior spinal artery originates from the 2 vertebral arteries at the level of the foramen magnum.
What does the anterior spinal artery supply?
The anterior spinal artery is a major artery providing nutrient-rich blood supply to the entire spinal cord section except for the dorsal columns. This artery runs along the entire length of the spinal cord anastomosing with other arteries.
Is anterior cord syndrome permanent?
Anterior cord syndrome is often a severe, life-changing disease. It affects multiple organ systems throughout the body and thus requires a team approach to optimally care for the patient.
Which is the most common type of spinal syndrome?
[1] Central cord syndrome, first described in 1954, is the most common form of incomplete spinal cord injury (SCI) and almost always occurs as a consequence of a blunt traumatic injury.
What part of the brain does the anterior spinal artery supply?
The anterior spinal artery supplies the anterior portion of the spinal cord and arises from the vertebral artery (V4, intradural segment) in the region of the medulla oblongata.
What feeds the anterior spinal artery?
The anterior spinal artery is located in the midline. In the cervical and upper thoracic cord, contributions to the anterior spinal artery are from the vertebral, cervical, and superior intercostal arteries. A small component of supply to the mid-thoracic cord arises from the mid-thoracic intercostal arteries.
Can you recover from a spinal cord stroke?
Can you survive a spinal stroke? A spinal cord stroke is a life threatening condition with an approximate mortality rate of 9% . However, this does mean that the vast majority of people survive a spinal cord stroke.
Where does anterior spinal artery terminate?
It is continued as a slender twig on the filum terminale. On its course the artery takes several small branches (i.e. anterior segmental medullary arteries), which enter the vertebral canal through the intervertebral foramina.
What are the symptoms of anterior cord syndrome?
Excerpt. Anterior cord syndrome is an incomplete cord syndrome that predominantly affects the anterior 2/3 of the spinal cord, characteristically resulting in motor paralysis below the level of the lesion as well as the loss of pain and temperature at and below the level of the lesion.
