Pleurodesis is a therapy that we offer for lung cancer patients to remove excess fluid—called pleural effusion—from the space between the lungs and chest wall that line the lungs (pleura). This fluid prevents the lungs from fully expanding as you breathe, causing shortness of breath. Pleural effusion is usually diagnosed by means of a chest x-ray, and a sample of the fluid may be taken to confirm its cause. There are a few ways to perform pleurodesis. One such way is video-assisted thoracoscopy, a new, less invasive method that we offer at BMC. Using a thoracoscope, a small, thin instrument with a light and lens, your surgeon will locate the area to be treated, drain your lung fluid, and then insert a talcum powder or antibiotic solution. This solution will circulate in the space between the pleura lining the chest wall and the lungs, causing some minor irritation and inflammation, which then causes the tissues to stick together, eliminating the space. Further fluid buildup is thereby prevented, allowing you to breathe easier. If the procedure is not successful, it may be repeated. Pleurodesis does not treat lung cancer, but it can be a very helpful tool in reducing symptoms.
