For example, an anteroposterior compressive force on a flexible tube filled with gelatin, a physical model of the contused spinal cord, produces longitudinal stress that is most intense in the center of the tube. 35 Thus, the vessels on the surface of the spinal cord are relatively spared from initial insult, whereas the microvasculature in the gray matter is subjected to stretching and shear stress, a consequence of the difference in compliance between the gray and white matter. 37 The 2013-08-01 · In fact, vascular insult to the cervical spinal cord generally only occurs as a result of degenerative osteophytes that compromise blood flow when the cervical spine is forcibly extended. The central cord syndrome occurs because the rich anastomosis is bypassed and the anterior spinal artery, the main supply to the cervical cord, is directly compromised [10] . spinal cord tumours (Roig et al. 1988), and prenatal insults of presumed vascular or viral origin (Darwish et al.

Transcranial electric motor evoked potentials are exquisitely sensitive to altered spinal cord blood flow due to either hypotension or a vascular insult. Moreover, changes in transcranial electric motor evoked potentials are detected earlier than are changes in somatosensory evoked potentials, thereby facilitating more rapid identification of impending spinal cord injury.

Illustration of Primary insult is disruption of neural and vascular structures of the spinal cord at the time of initial trauma. Secondary injury refers to a cascade of events  MAN WITH SUDDEN PARALYSIS: INSIDIOUS SPINAL CORD INFARCTION DUE spinal cord trauma, vascular injury, arterial dissection, spinal cord insult .

Rather, the spinal cord remains intact and the neurological damage is due to secondary vascular and pathogenic events, including oedema, inflammation and changes to the blood-spinal cord barrier. [11] Signs and symptoms vary depending on where the spine is injured and the extent of the injury but can include loss of power, sensation, respiration, temperature regulation, bladder, bowel and A spinal stroke is a disruption in the blood supply to the spinal cord.

We will then discuss injuries relating to patient position, spinal cord hypoperfusion and neuraxial techniques. Hence, adult onset TCS is often referred to as a tethered cord-tight filum syndrome, occult tethered cord, and normal conus-tight filum syndrome. 8,9,10 Similar to primary TCS, releasing of the tethered FT in adults has been shown to be efficacious in the resolution of symptoms and, perhaps, prevention of further deterioration of the spinal cord 7-10,12,27 Because of their different clinical In humans, perfusion of the thoracic spinal cord is largely dependent on the arterial supply from the aorta [].Segmental radiculomedullary arteries feed the anterior and posterior spinal arteries, which are the main circumferential arteries outside the cord parenchyma (known as ‘extrinsic’ arteries) [21, 75, 188–190]. Spinal cord arteries and veins represent tiny, millimeter-to-submillimeter blood vessels for which in vivo depiction has only recently become possible using noninvasive imaging techniques.
