Fascicular nerve biopsy in the dog
American Journal of Veterinary Research
|July 1, 1979
Summary
This study introduces a nerve fascicular biopsy technique in dogs, finding it preserves nerve function without causing deficits. Muscle analysis showed no significant differences, though small neuromas formed.
Area of Science:
- Veterinary Neurology
- Surgical Techniques
- Nerve Biopsy
Background:
- Nerve biopsies are crucial for diagnosing neurological conditions in animals.
- Preserving nerve function during biopsy is a significant challenge.
Purpose of the Study:
- To evaluate a novel nerve fascicular biopsy technique in dogs.
- To assess the functional and morphological impact of this biopsy method on peripheral nerves.
Main Methods:
- A fascicular biopsy technique was performed on the ulnar and peroneal nerves of dogs.
- Clinical examinations, electrodiagnostic tests (latency, duration, amplitude, conduction velocities), and morphometric muscle analysis were conducted.
- Histochemical techniques were used to delineate muscle fiber types.
Main Results:
- No clinical sensory or motor deficits were observed post-biopsy.
- Electrodiagnostic parameters remained largely unchanged.
- Morphometric analysis revealed no statistically significant differences in muscle fiber types between biopsied and control limbs.
- Small neuromas were consistently found at the biopsy sites.
Conclusions:
- The described nerve fascicular biopsy technique appears safe and preserves nerve integrity in dogs.
- This method may be a viable option for obtaining nerve tissue samples without compromising limb function.
- Further research is warranted to understand the long-term implications of neuroma formation.
