Fibrocartilaginous Embolism in Dogs

Fibrocartilaginous embolism (FCE), also known as spinal stroke, is a sudden blockage of the blood supply to the spinal cord caused by a piece of cartilage from the intervertebral disc. This condition is relatively uncommon in dogs, but it is seen more often in certain breeds and age groups. The severity of FCE can vary from mild weakness to complete paralysis, depending on the location and extent of the spinal cord affected.

The primary cause of FCE is the migration of cartilage from the intervertebral disc into the blood vessels of the spinal cord. This migration results in a blockage or embolism, disrupting blood flow and causing spinal cord injury. The precise way in which the fibrocartilaginous material enters the bloodstream remains unclear.

While there are no well-defined secondary causes, some cases of FCE may be preceded by physical activity or minor trauma. Despite this, these factors are not consistently observed in all cases, making them speculative rather than definitive causes.

Other contributing factors to FCE are largely speculative and not well understood. FCE is often described as a sudden and unpredictable event.

• German Shepherds
• Labrador Retrievers
• Irish Wolfhounds
• Miniature Schnauzers
• Great Danes
• Shetland Sheepdogs
• Old English Sheepdogs
• Doberman Pinschers
• Boxers
• Rottweilers

The primary symptom of FCE is a sudden onset of weakness or paralysis, typically affecting one side of the body more than the other. This sudden change can be alarming for dog owners and requires immediate attention.

Secondary symptoms may include a loss of coordination and an inability to walk. Dogs with FCE may also show pain when their spine is palpated, which can help differentiate FCE from other conditions.

Other symptoms can include incontinence or a lack of deep pain sensation in the affected limbs. These symptoms indicate a more severe spinal cord injury and may require a more intensive treatment approach.

Diagnosing FCE typically involves a combination of clinical signs and neurological examinations. Veterinarians will assess the dog’s symptoms and evaluate the affected areas to determine the extent of the spinal cord injury.

Imaging techniques like MRI are often used to help FCE. These tests can rule out other conditions, such as intervertebral disc disease, spinal tumors, and meningomyelitis, which are differential diagnoses for FCE.

By analyzing clinical signs and using advanced imaging, veterinarians can effectively diagnose FCE. This process is important to make sure proper supportive care and treatment plans are put into practice, improving the dog’s chances of recovery.

There is no specific treatment for FCE. However, supportive care, including rest and physical therapy, can significantly aid in recovery. Anti-inflammatory medications may also be prescribed to reduce pain and swelling.

Physical therapy plays an important role in the rehabilitation of dogs with FCE. It helps restore mobility and function, letting dogs regain strength and coordination. Consistent therapy sessions are essential for ideal recovery.

Managing FCE involves providing supportive care and ensuring the dog remains comfortable. A rehabilitation program is important to help the dog regain mobility and function.

Regular check-ups with the veterinarian are essential to monitor the dog’s progress. Changes to the management plan may be needed based on the dog’s recovery and overall health.

There are no known preventive measures for FCE, as its occurrence is often sudden and unpredictable. However, maintaining a healthy lifestyle and regular veterinary check-ups can help in early detection and management of potential health issues.

While FCE itself cannot be prevented, ensuring your dog maintains a balanced diet and regular exercise routine can contribute to overall spinal health. This may reduce the risk of other spinal conditions.
