Tobacco smoking cessation is strongly recommended since tobacco smoke exposure can worsen fibrosis. Severe cases of fibrothorax may require supportive mechanical ventilation if the affected person is unable to breathe adequately on their own.In cases of fibrothorax caused by medication, it is recommended that the offending medications be stopped. Ergot alkaloid medications, which can worsen pleural fibrosis, are typically avoided. Cases of fibrothorax attributable to medication typically stop worsening if the provoking medication is stopped. In some situations, medication-induced fibrothorax improves after stopping the causative medication but fibrothorax usually does not completely resolve.Watchful waiting is appropriate for milder cases of fibrothorax in certain situations. Fibrothorax caused by tuberculosis, empyema, or haemothorax often improves spontaneously 3–6 months after the precipitating illness. Corticosteroids are commonly used to treat fibrothorax but are not well-supported by available evidence. Surgical
In severe cases of fibrothorax that are compromising a persons ability to breathe, the scar tissue (fibrous peel) causing fibrothorax can be surgically removed using a technique called decortication. However, surgical decortication is an invasive procedure which carries the risk of complications including a small risk of death, and is therefore generally only considered if severe symptoms are present and have been for many months. Surgical decortication is generally considered for people with fibrothoraces that are severe, causing significant shortness of breath, and have otherwise relatively healthy lungs since this enhances the likelihood of a better outcome. Surgical removal of the pleura (pleurectomy) may be performed in refractory cases, as often happens when asbestosis is the cause.
Although fibrothorax may not cause any symptoms, people affected by the disorder may report shortness of breath. Persistent, recurrent pleural effusions are a possible symptom, caused by the persistent cavity formed by the hardening pleura around the original fluid collection. Shortness of breath tends to develop gradually and may worsen over time. Less commonly, fibrothorax may cause chest discomfort or a dry cough. Fibrothorax may occur as a complication of other diseases. Symptoms of the underlying problem are sometimes seen, for example, fever in cases of empyema. Causes
Fibrothorax is often a complication of other diseases that cause inflammation of the pleura. These include infections such as an empyema or tuberculosis, or bleeding within the pleural space known as a haemothorax. Exposure to certain substances, such as asbestos, can cause generalised fibrosis of the lungs, which may involve the pleura and lead to fibrothorax. Less common causes of fibrothorax include collagen vascular diseases such as systemic lupus erythematosus, sarcoidosis, and rheumatoid arthritis; kidney failure leading to uraemia; and side effects of certain medications. The medications most commonly associated with pleural fibrosis are the ergot alkaloids bromocriptine, pergolide, and methysergide. Fibrothorax may also occur without a clear underlying cause, in which case it is known as idiopathic fibrothorax. A technique called pleurodesis can be used to intentionally create scar tissue within the pleural space, usually as a treatment for repeated episodes of a punctured lung, known as a pneumothorax, or for pleural effusions caused by cancer.
