Summary
Bronchial stenting effectively treated airway collapse in dogs, improving quality of life and respiratory function. While complications like coughing occurred, they were manageable, indicating stenting is a viable option for advanced cases.
Area of Science:
- Veterinary Medicine
- Respiratory System Diseases
- Interventional Pulmonology
Background:
- Principal and lobar bronchial collapse is an emerging clinical entity.
- This condition can lead to significant respiratory dysfunction in dogs.
Purpose of the Study:
- To describe the procedure and outcomes of bronchial stenting in dogs with principal and lobar bronchial collapse.
- To evaluate the efficacy and complications of bronchial stenting in a canine population.
Main Methods:
- Retrospective review of nine client-owned dogs with collapse of the left principal bronchus (LPB) and lobar bronchi (LB1, LB2).
- All dogs underwent stenting of the LPB and LB2.
- Anatomic and functional impairment were graded before and 4 weeks after stenting.
Main Results:
- Bronchial stenting was successful in all cases, with improved quality of life and decreased functional impairment.
- Follow-up data showed long-term survival in most dogs.
- Complications included pneumothorax, pneumonia, and coughing, with most being resolvable or manageable.
Conclusions:
- Bronchial stenting is an effective treatment for advanced collapse of the LPB and LB2 in dogs.
- The procedure can resolve or improve life-threatening or quality-of-life-affecting clinical signs.
- Careful patient selection is crucial for successful outcomes, and ongoing coughing should be anticipated.

The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

241
Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

01:17Pulmonary Cycle: Exhalation
1.6K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

20
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
