Bronchial stenting

Advanced Bronchial Stenting for Improved Airway Function

Bronchial stenting is an advanced interventional pulmonology procedure used to keep a narrowed or blocked bronchus open and improve airflow into the lungs. A bronchial stent is a small medical device placed inside the affected airway to support its walls and maintain an adequate passage for breathing.

Bronchial stenting may be considered for selected patients with airway obstruction, bronchial stenosis, tumour-related blockage or certain benign airway conditions.

Dr. Aastha Gupta, Consultant Pulmonologist and Interventional Pulmonologist, provides specialized evaluation and advanced bronchoscopic treatment for patients with complex airway conditions.

What Is Bronchial Stenting?

The bronchi are the major airways that branch from the trachea and carry air into the right and left lungs. When a bronchus becomes narrowed or blocked, airflow to part of the lung can be reduced.

During bronchial stenting, a specially selected stent is placed within the affected bronchus to help maintain airway patency. The procedure is generally performed using bronchoscopy, allowing the pulmonologist to visualize the airway and accurately position the stent.

When Is Bronchial Stenting Recommended?

Bronchial stenting may be considered in appropriately selected patients with:

Bronchial stenosis or narrowing
Malignant airway obstruction
Tumour-related bronchial compression
Benign bronchial obstruction
Airway narrowing following certain procedures or injuries
Selected cases of airway collapse
Complex central airway obstruction

The decision to place a bronchial stent depends on the underlying cause, location and severity of the obstruction, symptoms and overall health of the patient.

Symptoms of Bronchial Obstruction

Bronchial narrowing or blockage can interfere with normal airflow and may cause:

Shortness of breath
Persistent cough
Wheezing
Chest discomfort
Reduced exercise tolerance
Recurrent or difficult-to-treat lung infections
Reduced airflow to part of the lung

Some patients may have symptoms that resemble asthma or other respiratory conditions. Appropriate imaging and airway evaluation can help identify the underlying problem.

How Is Bronchial Stenting Performed?

Before bronchial stenting, the airway is evaluated using appropriate investigations such as CT imaging and bronchoscopy. These assessments help determine the exact location and extent of the obstruction and guide stent selection.

During the procedure, a bronchoscope is introduced into the airways. The narrowed bronchus is carefully examined, and the appropriately sized stent is positioned across the affected area. The stent helps maintain an open airway and improve airflow.

The patient is monitored throughout the procedure, including oxygen saturation and other vital signs.

Benefits of Bronchial Stenting

For appropriately selected patients, bronchial stenting may:

Improve airflow through a narrowed bronchus
Relieve symptoms caused by airway obstruction
Improve breathing and exercise tolerance
Restore airway patency
Help manage selected malignant or benign airway obstructions

Bronchial stenting is generally part of an overall treatment strategy, and management of the underlying cause remains important.

Follow-Up After Bronchial Stenting

Regular follow-up is important after bronchial stent placement. Depending on the patient's condition, clinical assessment and follow-up bronchoscopy may be recommended to evaluate the stent and airway.

Potential complications can include mucus accumulation, infection, stent migration, granulation tissue and recurrent airway narrowing. New or worsening breathlessness, persistent cough, fever or other concerning symptoms should be reported promptly.
