Spinal stenosis is a common condition in which the spinal cord or the nerves exiting the spinal cord are constricted. In most patients, it occurs in the neck but it can also affect the lower back, and on very rare occasions it’s been known

Introduction: Spinal cord injury is one of the leading causes of paralysis and permanent morbidity. High cervical spine injuries, in particular, have the potential to be fatal and debilitating due to injury to multiple components, including but not limited to, discoligamentous disruption, vascular insult and spinal cord injury. Discussion. Subaxial cervical spine injuries often result in severe debility due to concomitant injury to the spinal cord.

It may be due to mechanical distortion or vascular ischaemia of the spinal cord arising from trauma, tumour, infection or other space-occupying lesions. The spinal cord blood supply is formed by many different vessels with an extensive collateral supply and drainage. Arterial supply The spinal cord is supplied by three longitudinal arteries: single anterior spinal artery: supplies the anterior Although direct penetrating trauma to the spinal cord is the commonest cause of Brown-Sequard Syndrome, patients with ischemic insult to the spinal cord from vertebral artery dissection may present with the syndrome. A thorough clinical exam should include evaluation for Brown-Sequard Syndrome, despite the lack of direct trauma to the cord. As more of the blood supply to the spinal cord is interrupted, the likelihood of paraplegia is increased. Various treatments are used to reduce the ischaemic insult to the spinal cord including temporary blood shunts (such as distal atriofemoral bypass and re-connection of intercostal and lumbar vessels), pharmaceutical interventions (to protect the heart and cerebral blood vessels), epidural Ischemic spinal cord infarction is rare in the paediatric population, and when it does occur, it is usually associated with traumatic injury. Other potential causes include congenital cardiovascular malformations, cerebellar herniation, thromboembolic disease and infection.

Vascular Malformations and Hemangiomas of the Canine Spinal Cord D. R. CORDY Department of Pathology, School of Veterinary Medicine, University of California, Davis, Calif. Abstract. An arteriovenous malformation and two hemangiomas in the canine spinal cord were found in three dogs. The malformation was ventral, extramedullary and largely subdural.

Spinal claudication is to be distinguished from vascular claudication by noting that standing and walking in the upright position causes a similar kind of pain into the legs, which in turn is relieved when the patient bends over forward, like resting on the push bar of a shopping trolley. Cerebral insult and brain and spinal cord injuries Cerebral insult (insult, weakness, cerebral palsy) is a sudden neurological deficit caused by disturbance of brain blood flow.

The term includes both ischemic and hemorrhagic incident. Ischemic cerebral insult happens when a blood clot or embolus blocks or slows down blood flow in the brain artery, thus blocking transport of oxygen and glucose that are necessary for regular function of the brain. Transcranial electric motor evoked potentials are exquisitely sensitive to altered spinal cord blood flow due to either hypotension or a vascular insult.

2011-03-07 · 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].

MAN WITH SUDDEN PARALYSIS: INSIDIOUS SPINAL CORD INFARCTION DUE spinal cord trauma, vascular injury, arterial dissection, spinal cord insult .

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. A brief overview of the complex and clinically relevant vascular anatomy of the spinal cord is provided, including the supplying and draining trajectories. Results—The vascular anatomy of the mouse and human spinal cord appeared similar in that blood was supplied by 1 anterior and 2 posterior spinal arteries and heterosegmental radicular arteries. During combined occlusion of aortic arch and left subclavian artery, mean distal arterial blood pressure dropped to 10±5 mm Hg, and spinal cord blood flow at the L1 level decreased to 27±7% of baseline.
