In the medical community, effusion refers to the escape of fluid from a vessel into a body cavity. The term effusion is derived from the Latin word "effusio," meaning pouring out. Effusion occurs when too much fluid is present, causing the fluid to flow out of the vessel where it originated.
Mesothelioma patients may experience certain types of effusion as a result of their exposure to asbestos. One of the more common types is pleural effusion.
Pleural effusion results when fluid accumulates between the two membranes that surround the lungs, known as the pleura. The pleura mesothelioma is comprised of two separate membranes and provides protection for the lungs and chest cavity.
The parietal layer is the outer membrane that lines the entire chest cavity while the visceral layer is the inner layer that covers the lungs. Pleural mesothelioma effusion occurs when the fluid between the two layers increases. Symptoms of pleural effusion may include chest pains and difficulty breathing caused by fluid buildup.
Patients with pleural effusion may undergo a surgical procedure known as thoracentesis to help relieve symptoms associated with the condition. This involves the use of a very thin needle to extract fluid from the pleura.
A doctor may also recommend pleurodesis as a treatment option for patients with pleural effusion. During the surgical procedure, fluid is drained and the pleural mesothelioma space is then treated with a chemical that causes inflammation. This then causes the pleural space to close up, preventing additional fluid buildup.
