Sindroma Kauda Equina

Definition

Cauda equina syndrome is a disorder that affects the nerve fibers in the lumbar region, which is the lowest part of the spine. This syndrome can lead to disturbances in motor and sensory functions of the limbs and can develop rapidly or over a long period. It is a medical emergency that requires immediate treatment. Early therapy can prevent extensive and permanent nerve damage in patients.

Cauda equina, meaning "horse's tail" in Latin, describes the shape of the nerve fibers in the lower back. These fibers conduct nerve signals to and from the toes, feet, and hips. Cauda equina syndrome occurs more frequently in adults than in children. In children, the most common causes are congenital spinal abnormalities or spinal injuries. In the United States, cauda equina syndrome affects one in 30,000 to 100,000 people annually.

 

Causes

Cauda equina syndrome can be caused by structural abnormalities, inflammation, swelling, or trauma to the spine. Some causes of cauda equina syndrome include:

  • Herniated discs pressing on the nerve fibers in the spine.
  • Spinal tumors.
  • Infections that cause inflammation or bleeding, compressing the nerve fibers.
  • Fractures or dislocations of bones, which can press on the nerve fibers. Bleeding can also compress the nerve fibers.
  • Narrowing of the spinal canal.
  • Complications from severe trauma, such as traffic accidents, falls, or stab wounds.
  • Congenital abnormalities (e.g., abnormal blood vessel formation).

 

Risk factor

One of the most significant risk factors for cauda equina syndrome is a history of herniated spinal discs. Each vertebra is separated by a cushion-like disc that acts as a shock absorber. A herniated or compressed disc can disrupt the surrounding nerve fibers. Prolonged damage can increase the risk of cauda equina syndrome.

 

Symptoms

Symptoms of cauda equina syndrome vary based on severity. Mild cases may present with back pain or no pain at all, depending on the cause and location of the disturbance, such as a tumor. Other symptoms include:

  • Pain in one or both legs, accompanied by numbness, which can make sitting or standing difficult.
  • Loss of sensation or numbness in the buttocks, inner thighs, legs, and toes.
  • Urinary or bowel dysfunction, such as difficulty urinating or incontinence.
  • Sudden sexual dysfunction.

These symptoms are usually progressive and worsen without treatment. Cauda equina syndrome symptoms are serious and require immediate medical attention.

 

Diagnosis

To diagnose cauda equina syndrome, a doctor will take a medical history, including any history of back pain, infections, or tumors. The doctor will assess muscle strength and motor and sensory function in the legs. Supporting diagnostic tests include:

  • Blood tests.
  • Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) scans.
  • Myelogram, which uses X-rays and contrasts fluid to highlight pressure points on the spinal nerve fibers.

MRI or CT scans provide a clear view of the spine's anatomy and can identify the cause of symptoms or rule out other diseases with similar symptoms. MRI is the gold standard for diagnosing cauda equina syndrome and should ideally be performed within an hour of symptom onset.

 

Management

Initial treatment for cauda equina syndrome involves relieving pressure on the nerve fibers to prevent permanent damage, such as paralysis, urinary and bowel dysfunction, sexual dysfunction, and other issues. The best treatment is given within 48 hours of symptom onset.

High-dose corticosteroids can reduce inflammation and swelling in cauda equina syndrome cases. Further treatment depends on the cause. Infections are treated with antibiotics, and tumors may require surgery, such as laminectomy, chemotherapy, or radiotherapy.

 

Complications

Untreated cauda equina syndrome can lead to incontinence and permanent paralysis in both legs. Some residual symptoms may persist after treatment but can improve over time. Nerve damage affecting urination can be managed with a urinary catheter three to four times daily. Bowel difficulties can be managed with enemas or glycerin suppositories.

If nerve damage is permanent, regular treatment, along with emotional and physical support, is essential. Patients need time to adapt to living with cauda equina syndrome. Joining support groups can help patients understand the next steps in managing their condition.

 

Prevention

While there are no specific measures to prevent cauda equina syndrome, early diagnosis and treatment are crucial. Any back or leg pain should be evaluated to rule out cauda equina syndrome.

 

When to see a doctor?

Cauda equina syndrome is an emergency. Seek immediate medical help if you experience any of the following symptoms:

  • Pain in one or both legs, accompanied by numbness.
  • Loss of sensation or numbness in the buttocks, inner thighs, legs, and toes.
  • Urinary or bowel dysfunction, such as difficulty urinating or incontinence.
  • Sudden sexual dysfunction.
  • Back pain or no pain.

Recognizing the symptoms of cauda equina syndrome is crucial for preventing permanent damage. It is important to discuss your test results with your doctor for a proper diagnosis and management.
