Spinal Arachnoid Diverticula: Outcome in 96 Medically or Surgically Treated Dogs

Area of Science:

• Veterinary Neurology
• Neurosurgery
• Comparative Medicine

Background:

• Spinal arachnoid diverticula (SAD) are poorly understood in canine medicine.
• Limited data exists on the efficacy of medical management for SAD in dogs.

Purpose of the Study:

• To evaluate and compare the outcomes of medical versus surgical treatment for spinal arachnoid diverticula (SAD) in dogs.
• To identify factors influencing treatment success in canine SAD.

Main Methods:

• A retrospective case series analyzed 96 dogs diagnosed with SAD.
• Dogs were categorized into medical management (n=50) or surgical treatment (n=46) groups.
• Outcome assessment utilized a standardized questionnaire with a median follow-up of 16-23 months.

Main Results:

• Surgical intervention resulted in an 82% improvement rate, significantly higher than the 30% improvement seen with medical management (P = .0002).
• Dogs treated surgically were significantly younger than those receiving medical management.
• No significant differences in clinical presentation were noted between the treatment groups.

Conclusions:

• Surgical treatment appears to be more effective than medical management for canine spinal arachnoid diverticula.
• Further research with standardized protocols is recommended to confirm these findings and optimize patient care for SAD.
