A double membrane, called the pleura, surrounds the lungs and lines the ribs. The space in between the two membranes is called the pleural cavity. Pneumothorax is when air penetrates the pleural cavity. Air that comes from a weak area in the lung (a “hole” in the lung) causes it to collapse. This phenomenon may be local, at the top of the lung (apex), or it may extend to the entire lung.
Pneumothorax is more common in men and affects mostly young people (between 20 and 40 years old). Smoking is an aggravating factor.
There are several types of pneumothorax:
The treatment of pneumothorax varies from simple rest to surgery. Initially, an attempt is made to remove the accumulated air, under local anesthesia, by means of a needle (pleural aspiration) or by drainage. In tension, recurrent or bilateral pneumothorax, surgical treatment is considered.
The intervention involves surgical removal of the area of lung weakness that is causing the pneumothorax. In order to reduce the risk of recurrence, surgeons perform pleurodesis, which sticks the two pleural walls together.
Pleurodesis is performed in three ways:
These three surgical procedures are performed by thoracoscopy.
