Spinal cord infarction

Spinal cord infarction is a stroke within the spinal cord or the arteries that supply it. It is caused by arteriosclerosis or a thickening or closing of the major arteries to the spinal cord. Frequently, spinal cord infarction is caused by a specific form of arteriosclerosis called atheromatosis, in which a deposit or accumulation of lipid-containing matter forms within the arteries.

Symptoms, which generally appear within minutes or a few hours of the infarction, may include:

  • Intermittent sharp or burning back pain
  • Aching pain down through the legs
  • Weakness in the legs
  • Paralysis, loss of deep tendon reflexes
  • Loss of pain and temperature sensation
  • Incontinence

    Treatment is symptomatic. Physical and occupational therapy may help individuals recover from weakness or paralysis. A catheter may be necessary for individuals with urinary incontinence.

    Recovery depends upon how quickly treatment is received and how severely the body is compromised. Paralysis may persist for many weeks or be permanent. Most individuals have a good chance of recovery.

    How can I or my loved one help improve care for people with spinal cord infarction?

    Consider participating in a clinical trial so clinicians and scientists can learn more about spinal cord infarction and related disorders. Clinical research uses human volunteers to help researchers learn more about a disorder and perhaps find better ways to safely detect, treat, or prevent disease.

    All types of volunteers are needed—those who are healthy or may have an illness or disease—of all different ages, sexes, races, and ethnicities to ensure that study results apply to as many people as possible, and that treatments will be safe and effective for everyone who will use them.
