Tracheal obstructions in two horses and a donkey.
The Veterinary Record
|March 31, 1990
Summary
Intramural tracheal obstructions in horses and donkeys cause respiratory distress due to abnormal cartilage ring shapes. These developmental issues, located at the thoracic inlet, are diagnosed using endoscopy and radiography.
Area of Science:
- Veterinary Medicine
- Equine Respiratory Diseases
Background:
- Intramural tracheal obstructions are rare conditions affecting equine respiratory health.
- Understanding the etiology and clinical presentation is crucial for diagnosis and management.
Observation:
- Two horses and a donkey presented with respiratory distress and coughing, exacerbated by exercise.
- Clinical signs indicated obstructions at the thoracic inlet level.
Findings:
- Tracheal cartilage rings exhibited abnormal conformations: flattening in the dorsoventral plane or scroll-like shapes.
- These abnormalities appeared developmental and chronic, preceding clinical manifestation.
Implications:
- Endoscopy and radiography are valuable diagnostic tools for identifying these tracheal abnormalities.
- Early diagnosis can lead to improved management strategies for equine respiratory distress.
