Brief Summary:
Emphysema is a progressive phenotype of chronic Obstructive Pulmonary Disease (COPD), poses a significant global health burden characterized by irreversible lung parenchymal destruction and airspace enlargement.
In recent years, bronchoscopic lung volume reduction (BLVR) has considerable interest as a minimally invasive approach to reducing hyperinflation and improving lung function in patients with emphysema.
BLVR techniques aim to achieve lung volume reduction by occluding or ablating emphysematous lung tissue through endobronchial delivery of various agents. Many techniques are available for BLVR as coil, endo-bronchial valve, and biological as thrombin, autologous blood and chemicals as silver nitrate solution.
Detailed Description:
Emphysema is a progressive phenotype of chronic Obstructive Pulmonary Disease (COPD), poses a significant global health burden characterized by irreversible lung parenchymal destruction and airspace enlargement.
In recent years, bronchoscopic lung volume reduction (BLVR) has considerable interest as a minimally invasive approach to reducing hyperinflation and improving lung function in patients with emphysema.
BLVR techniques aim to achieve lung volume reduction by occluding or ablating emphysematous lung tissue through endobronchial delivery of various agents. Many techniques are available for BLVR as coil, endo-bronchial valve, and biological as thrombin, autologous blood and chemicals as silver nitrate solution.
Chemical lung volume reduction is an endo-bronchial approach, which uses chemical agents aiming to reduce lung volume by blocking off the most emphysematous areas with a rapidly polymerizing sealant. Endobronchial Valves (EBVs) show an overall success rate of 70-80% in reducing lung volume and improving lung function. Lung volume reduction coils (LVRC-Coils) have a success rate of 50-60%.
Bronchoscopic lung volume reduction with silver nitrate as a chemical agent was used in previous studies using a concentration of 0.5% and showed significant improvement in forced expiratory volume in first second (FEV1), diffusion capacity of lung to carbon monoxide (DLCo), modified Medical Research Council (mMRC) score when compared to base line values and reduction of the High Resolution Computed Tomography (HRCT) volumetry of the emphysematous regions.
Silver nanoparticles (AgNPs) are the most widely used nanomaterial today. These have found a wide range of applications in various areas such as textiles, agriculture, renewable energy, food, catalysis, bioremediation, and biomedicine
