Chemical pleurodesis for first presentation of primary spontaneous pneumothorax

Primary spontaneous pneumothorax (PSP) most commonly occurs in young, tall, lean males. The PSP recurrence rate varies between 16 and 52 % after the first episode. This high recurrence rate has stimulated the development of different therapeutic approaches, ranging from simple aspiration to invasive therapies, including chemical pleurodesis or surgery. Chemical pleurodesis is a procedure which uses sclerosing agents to cause adhesion between the two layers of the pleura. Traditionally, chemical pleurodesis for PSP has been recommended only if the patient is unwilling or unable to undergo surgery. However, several prospective, randomized trials have shown that additional chemical pleurodesis following simple aspiration or chest tube drainage is a safe and more effective initial treatment for PSP than simple aspiration and drainage alone and significantly reduces pneumothorax recurrence and subsequent thoracic surgery. In this article, the role of chemical pleurodesis in the first presentation of PSP is reviewed.
