Severe emphysema can cause persistent shortness of breath, reduced exercise capacity, and hyperinflation that makes breathing increasingly difficult. Most patients are first treated with medications, pulmonary rehabilitation, smoking cessation support, oxygen when appropriate, and other therapies designed to improve breathing and daily function. For selected patients whose symptoms remain severe despite optimized treatment, lung volume reduction can help by reducing the amount of damaged, overinflated lung tissue and allowing healthier portions of the lung to work more efficiently.
Lung volume reduction may be performed surgically or, in selected patients, through bronchoscopic procedures such as endobronchial valve treatment. Determining the best approach requires careful evaluation of the pattern and severity of emphysema, the degree of hyperinflation, lung function, exercise capacity, overall health, and the anatomy of the affected lung.
What Is Lung Volume Reduction Surgery (LVRS)?
Lung volume reduction surgery is a treatment for carefully selected patients with advanced emphysema and significant hyperinflation. During LVRS, surgeons remove the most severely damaged areas of lung tissue, reducing the overall size of the overinflated lungs. This can allow the remaining healthier lung tissue and diaphragm to work more efficiently and may improve breathing, exercise tolerance, and quality of life.
LVRS is not appropriate for every patient with emphysema. Evaluation typically includes pulmonary function testing, chest CT imaging, exercise assessment, and review of the patient’s overall health and response to medical treatment and pulmonary rehabilitation.
How Does LVRS Help Severe Emphysema?
Emphysema damages the walls of the air sacs and reduces the lung’s natural elasticity. As a result, air becomes trapped during exhalation and the lungs can become chronically overinflated. Hyperinflation can flatten the diaphragm, increase the work of breathing, and limit the amount of healthier lung tissue that can expand normally.
By removing selected areas of the most damaged and overinflated lung, LVRS can reduce hyperinflation and improve the mechanics of breathing. The benefit is greatest in carefully selected patients, particularly when imaging shows a pattern of emphysema that is well suited to surgical volume reduction.
Who May Be a Candidate for LVRS?
LVRS is generally considered for patients with severe emphysema who continue to experience significant shortness of breath and activity limitation despite optimized medical therapy and pulmonary rehabilitation. Patient selection is one of the most important factors in achieving a good outcome.
Symptoms and Functional Limitations
Patients considered for LVRS often have severe shortness of breath with everyday activities such as walking, climbing stairs, bathing, dressing, bending, or carrying objects. Reduced exercise tolerance and persistent hyperinflation despite appropriate treatment are important considerations during evaluation.
CT Imaging and Emphysema Distribution
Chest CT imaging helps determine which parts of the lungs are most affected and whether there is a heterogeneous pattern in which some areas are significantly more damaged than others. Patients with upper-lobe-predominant heterogeneous emphysema have historically shown some of the strongest benefits from LVRS, although treatment decisions require consideration of the complete clinical picture.
Pulmonary Function and Exercise Testing
Pulmonary function tests help measure airflow obstruction, lung volumes, gas exchange, and the degree of hyperinflation. Exercise testing and assessment of oxygen needs may also be used to understand how severely emphysema is affecting daily function and whether the potential benefits of surgery outweigh the risks.
Overall Health and Surgical Risk
Heart health, nutritional status, smoking status, other lung conditions, and the ability to participate in pulmonary rehabilitation are considered before surgery. Patients with extremely limited lung function or certain patterns of diffuse emphysema may face greater operative risk and may be better suited to another treatment approach.
How Is Lung Volume Reduction Surgery Performed?
LVRS removes selected portions of severely damaged lung tissue, often from the upper regions of the lungs when emphysema is concentrated there. The amount and location of lung removed are determined from imaging and physiologic testing rather than by a fixed surgical formula.
Many LVRS procedures can be performed using minimally invasive techniques such as video-assisted thoracoscopic surgery (VATS), while open surgery may still be appropriate in selected circumstances. The goal is to achieve effective lung volume reduction while minimizing unnecessary surgical trauma.
Benefits and Risks of LVRS
For appropriately selected patients, LVRS can improve shortness of breath, exercise capacity, lung function, and quality of life. The degree and duration of improvement vary among patients and depend strongly on emphysema distribution, baseline lung function, exercise capacity, and overall health. Recent evidence continues to support meaningful functional benefits from LVRS in selected patients with severe emphysema. :contentReference[oaicite:1]{index=1}
LVRS is a major thoracic operation and carries risks including prolonged air leak, pneumonia, bleeding, heart complications, respiratory failure, and death. These risks make careful patient selection and treatment at an experienced center especially important. Modern minimally invasive techniques can reduce some aspects of surgical recovery, but they do not eliminate the inherent risks of the procedure.
Bronchoscopic Lung Volume Reduction
Some patients with severe emphysema may be candidates for bronchoscopic lung volume reduction rather than surgery. One established approach uses endobronchial valves placed through a bronchoscope to block airflow into a severely damaged portion of the lung, allowing that area to decrease in volume and reducing hyperinflation.
Endobronchial valve therapy is most effective in carefully selected patients whose lung anatomy allows the treated lobe to deflate without significant collateral airflow from neighboring lobes. CT analysis, pulmonary function testing, and specialized assessment of fissure integrity and collateral ventilation help determine whether valve treatment may be appropriate. :contentReference[oaicite:2]{index=2}
Surgical and bronchoscopic lung volume reduction are not interchangeable for every patient. Each has different benefits, risks, and selection criteria, which is why evaluation by an experienced pulmonary and thoracic team is important. Recent comparative research continues to support individualized decision-making rather than assuming one approach is universally superior. :contentReference[oaicite:3]{index=3}

Advanced Thoracic Care for Severe Emphysema
At Providence Saint John’s Health Center, patients with severe emphysema are evaluated by pulmonary and thoracic specialists to determine whether lung volume reduction may improve breathing and daily function. Treatment planning considers the distribution of emphysema, degree of hyperinflation, lung function, exercise capacity, overall health, and response to medical therapy and pulmonary rehabilitation.
For appropriately selected patients, options may include lung volume reduction surgery or bronchoscopic lung volume reduction using endobronchial valves. The goal is to reduce hyperinflation, improve respiratory mechanics, and help patients breathe and function more comfortably while selecting the approach that offers the best balance of potential benefit and risk.
If severe emphysema continues to limit your breathing and daily activities despite treatment, our pulmonary and thoracic specialists can help determine whether lung volume reduction may be an option.
