This occurs as the spinal nerves or spinal cord become increasingly trapped in a smaller space within the canal. Determining whether pain in the elderly is caused by lack of blood supply or stenosis is difficult; testing can usually differentiate between them, but patients can have both vascular disease in the legs and spinal stenosis.
Vascular myelopathy (vascular disease of the spinal cord) refers to an abnormality of the spinal cord in regard to its blood supply. [1] The blood supply is complicated and supplied by two major vessel groups: the posterior spinal arteries and the anterior spinal arteries—of which the Artery of Adamkiewicz is the largest. [2]
When due to trauma, myelopathy is known as (acute) spinal cord injury. When inflammatory, it is known as myelitis. Disease that is vascular in nature is known as vascular myelopathy. In Asian populations, spinal cord compression often occurs due to a different, inflammatory process affecting the posterior longitudinal ligament. [citation needed]
Both neurogenic claudication and vascular claudication manifest as leg pain with walking, but several key features help distinguish between these conditions. [7] In contrast to NC, vascular claudication does not vary with changes in posture. [9] Patients with vascular claudication may experience relief with standing, which may provoke symptoms ...
Such severe spinal stenosis symptoms are virtually absent in lumbar stenosis, however, as the spinal cord terminates at the top end of the adult lumbar spine, with only nerve roots (cauda equina) continuing further down. [15] Cervical spinal stenosis is a condition involving narrowing of the spinal canal at the level of the neck.
Neurogenic shock results from damage to the spinal cord above the level of the 6th thoracic vertebra. [5] It is found in about half of people who have a spinal cord injury within the first 24 hours, and usually persists for one to three weeks. [5] Neurogenic shock may be caused by severe brain injury. [6]
Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...
The anterior portion of the spinal cord is supplied by the anterior spinal artery. It begins at the foramen magnum where branches of the two vertebral arteries exit, merge, and descend along the anterior spinal cord. As the anterior spinal artery proceeds inferiorly, it receives branches originating mostly from the aorta. [1]
