Summary
A modified nomenclature system aids in identifying equine airways during bronchoscopy. This standardized approach enhances the description of lobar, segmental, and subsegmental bronchi for better diagnostic accuracy in horses.
Area of Science:
- Veterinary Anatomy
- Equine Respiratory System
Background:
- Bronchoscopy is crucial for diagnosing equine respiratory diseases.
- Accurate identification of airway structures is essential for effective diagnosis and treatment.
Purpose of the Study:
- To modify the Amis and McKiernan nomenclature system for equine endobronchial anatomy.
- To establish a standardized method for identifying airways during equine bronchoscopy.
Main Methods:
- Evaluation of endobronchial anatomy in 12 equine lung specimens and 12 live horses using videoendoscopy.
- Modification of existing nomenclature to describe lobar, segmental, and subsegmental bronchi.
Main Results:
- A modified nomenclature system was developed based on the side and order of origin for lobar bronchi (e.g., RB1, RB2, RB3; LB1, LB2).
- Segmental bronchi are identified by number and direction (D, V, L, M, R, C).
- Subsegmental bronchi are further identified using lowercase letters and sequential numbering for branching.
Conclusions:
- The modified nomenclature provides a systematic approach to describing equine airways.
- This standardized system improves the precision and consistency of bronchoscopic findings in horses.
