Endobronchial Valve Therapy (EBV) is a minimally-invasive treatment that is mostly used to treat those suffering from extreme Emphysema and chronic air leaks within the lung. These conditions can cause lower lung function and poor the quality of life. By putting one-way valves into the airways EBV assists in directing airflow to enhance the effectiveness of breathing. understanding of the causes for endobronchial valve therapy ,What is the reason behind the need for this therapy?
What Is Endobronchial Valve Therapy?
Before we get into the causes it’s essential to comprehend the basics of what EBV is. Endobronchial Valve Therapy involves placing small, one-way valves inside specific airways in the lung with the Bronchoscope. The valves permit air trapped and secretions to escape, while stopping air from entering damaged regions. This results in diminution in lung volume which allows the more healthy areas of the lungs to function better.
EBV is FDA-approved to treat certain types of severe Emphysema and extended breathing leaks.
Top Causes for Endobronchial Valve Therapy
1. Severe Emphysema (Chronic Obstructive Pulmonary Disease – COPD)
One of the main reasons for EBV treatment is advanced Emphysema an emphysema-like subtype of COPD. Emphysema can cause the destruction of the alveoli, leading to air entrapping and hyperinflation of the lung. This can make it hard for the patient to breath deeply and exhale efficiently.
In these cases:
-
It is believed that the inhalation of air in the damaged lung regions creates pressure.
-
Breathing becomes slow and inefficient.
-
Quality of life is seriously affected.
EBV provides a solution collapse of the lung segment affected by disease and allowing the lung segment to expand to its fullest and function at its best.
2. Lung Hyperinflation
Lung hyperinflation happens when air gets trapped in the lungs when exhaling usually because of diminished airway elasticity or obstruction of the airway. It can cause:
-
Breathlessness (dyspnea)
-
Decreased lung capacity
-
Exercise tolerance is limited.
Patients suffering from diverse emphysema–where the damage to the lungs is uneven, benefit the most from EBV since valves may put in most affected lung lobes to relieve the lungs of pressure.
3. Persistent Air Leaks (PALs)
persistent air leaks are a different reason to undergo endobronchial valve therapy. These are caused by an ongoing leakage of lung air into the pleural space because of:
-
Lung surgery
-
Lung biopsy
-
Trauma
-
Pneumothorax (collapsed lung)
Traditional treatment may involve the use of chest tubes or surgery however, in non-surgical patients, EBV provides a lower-risk alternative which helps to stop the air leakage and encourage healing.
4. Giant Bullae or Bullous Disease
The bullae are air-filled spaces within the lungs, caused by the destruction of lung tissue. In some instances, bullae may enlarge healthy lung tissue, decreasing lung function.
Some of the symptoms are:
-
Breathlessness
-
Chest tightness
-
The risk of pneumothorax that is spontaneous
Endobronchial valves may be employed to reduce and isolate the bullae to improve breathing mechanics.
5. Post-Surgical Complications
Following an operation to remove the lung there are patients who experience complications, such as:
-
Bronchopleural fistula (BPF)
-
Long-term air leakage
-
Delay in healing
EBV is an important tool to treat these conditions to avoid reoperation and speeding recovery.
Who Is a Candidate for Endobronchial Valve Therapy?
To be eligible to be eligible for EBV Patients typically go through:
-
CT scans are used to evaluate the lung anatomy
-
PFTs are tests of the function of the lungs. (PFTs)
-
Chartis(r) evaluation to determine if there is no collateral ventilation
The most effective candidates include:
-
Heterogeneous Emphysema (one one of the lobes is more damaged)
-
Hyperinflation severe and severe
-
A lack of significant collateral ventilation
Symptoms That Lead to EBV Consideration
Understanding the signs that signal a potential need for EBV can aid in identifying early signs of EBV:
-
Breathlessness that is chronically short
-
Physical activity is limited
-
Chronic cough
-
Exacerbations frequently exacerbate COPD
-
Saturation of oxygen is reduced
-
Recurrent pneumothorax
If these symptoms continue to persist despite an effective medical treatment, endobronchial treatment is an important factor to consider.
Diagnosis Before EBV Therapy
1. Imaging Tests
-
High-Resolution CT scan (HRCT): Identifies the lobes of interest, bullae as well as air-trapping areas.
-
Perfusion Scan Analyzes the airflow distribution.
2. Lung Function Tests
-
FEV1 (Forced Expiratory Volume)
-
Residual Volume (RV)
-
DLCO (Diffusing ability of the lung to absorb carbon monoxide)
3. Chartis Assessment
Utilized during bronchoscopy to test to see if there is collateral ventilation as a crucial indicator of EBV effectiveness.
Treatment Goals of Endobronchial Valve Therapy
The principal objectives for EBV are:
-
Reduce lung hyperinflation
-
Improve the efficiency of your breathing
-
Reducing dyspnea
-
Increase fitness capacity
-
Do not delay or avoid the procedure
-
Reduce hospital readmissions
Conclusion
Endobronchial Valve Therapy is a innovative treatment for patients with serious pulmonary diseases such as Emphysema as well as chronic lung leaks. Knowing the reasons of this treatment–ranging between the hyperinflation of the lung, collapsed lungs to problems post-surgery–helps doctors and patients make informed choices about the management of lung health.
With the advancement of minimally-invasive methods, EBV has emerged as an reliable, safe and long-lasting treatment alternative. If you or someone you love is suffering from lung cancer that has advanced you should consult a pulmonologist assess whether Endobronchial Valve Therapy is the appropriate choice for you.
