Pleurodesis is a procedure that produces controlled adhesion between the pleural layers, sealing the pleural space around the lung to help prevent fluid or air from collecting there.
The lungs are covered by a thin lining called the visceral pleura. The inside of the chest wall is lined by the parietal pleura. The small gap between these layers is called the pleural space. Pleural space anatomy along the chest wall determines how fluid or air collects within it. Normally, this space contains only a small amount of fluid to help the lung move smoothly during breathing.
Pleurodesis works by causing the two pleural layers to adhere. Once the space is sealed, there is less room for fluid or air to return. This can help patients with recurrent pleural effusion, repeated pneumothorax, or selected cancer-related fluid around the lung.
Pleurodesis does not treat every underlying disease. For example, in malignant pleural effusion, it does not cure the cancer. Its main aim is to control the symptoms, reduce recurrence, and help keep the lung expanded. In pneumothorax, the aim is to lower the risk of another lung collapse.
There are different types of pleurodesis.
Surgical pleurodesis may be done through Video-Assisted Thoracoscopic Surgery (VATS) or through open thoracotomy in selected cases.
Pleurodesis is mainly used to treat recurrent pleural effusions and recurrent pneumothoraces.
Pleurodesis indication for individual patients depends on the cause, symptoms, lung expansion in the pleural space, expected benefit and overall health. It is not suitable for all patients with pleural fluid or a pneumothorax. If the lung is trapped and cannot expand, pleurodesis is less likely to succeed because the pleural layers cannot come into contact properly.
You should see a thoracic specialist if fluid or air around the lung keeps returning, does not drain well, or causes persistent breathlessness.
A specialist review and thoracic surgery assessment are important when pleural effusion or pneumothorax has occurred more than once. It is also important if a chest drain has not solved the problem, if the lung does not re-expand, or if scans suggest trapped lung, pleural thickening, infection, cancer or loculated fluids.
Neumark Lung & Chest Surgery Centre’s specialists can assess whether pleurodesis surgery is appropriate and whether it should be performed via chest tube, medical thoracoscopy, VATS pleurodesis, uniportal VATS, or another approach. The best option depends on the diagnosis, the patient’s anatomy, disease stage, lung expansion, treatment goals, and the patient’s fitness for anaesthesia.
In Singapore, timely thoracic surgery assessment can help patients avoid repeated emergency drainage, prolonged symptoms, and delays in cancer or pleural disease treatment.
Preparation for pleurodesis focuses on confirming the cause, checking lung expansion, and making the procedure as safe as possible.
If fluid is present, a sample may be tested for infection, cancer cells, protein, glucose, pH, cell count, and other markers. Pleurodesis efficacy depends on pleural fluid biochemistry, and such tests guide the patient’s treatment.
If the diagnosis is unclear, a pleural biopsy may be needed before or during the procedure.
The lung must usually be able to expand after fluid or air is drained. If the lung remains trapped, pleurodesis may not work well. In that case, alternatives such as an indwelling pleural catheter or decortication may be considered.
You may be asked not to eat or drink for several hours before surgical pleurodesis or VATS pleurodesis. Your care team will explain what medicines to take, what to stop, and whether you should expect local anaesthesia, sedation, or general anaesthesia. Your doctor may also advise avoiding non-steroidal anti-inflammatory drugs (NSAIDs) after pleurodesis because these medicines reduce inflammation, which may affect how well the pleural layers seal.
During the procedure, the pleural space is drained and then treated so that the lung lining adheres to the chest wall.
The pleurodesis procedure may take 30 minutes to a few hours in the operating room, depending on the method used and whether other procedures are done at the same time. Talc pleurodesis is a commonly performed medical procedure in this setting.
If VATS is used, the surgeon may also inspect the pleura, take biopsies, treat air leaks, remove abnormal tissue, or perform partial pleurectomy if needed.
After pleurodesis, you are monitored while the lung stays expanded, and the chest drain removes the remaining fluid or air.
Pleurodesis complications can include pain, fever, infection, bleeding, air leaks, failed pleurodesis, and breathing problems.
Pain is common among patients because pleurodesis induces controlled inflammation. Fever can also occur in some patients after chemical pleurodesis. The effects of this medical procedure are usually managed with medicines and close monitoring. Adverse events are uncommon overall.
Possible complications include wound infections at the chest wall, chest infections, bleeding, pneumothorax, persistent air leaks, low oxygen levels, fluid re-accumulation, or failure of the pleural layers to seal. Infection can occur if an aseptic technique is not maintained during the tube placement, medication administration, or drain care. Rare but serious complications of the procedure can include severe breathing difficulty or infection in the pleural space.
Acute respiratory distress syndrome (ARDS) has been reported in rare patients with talc use. This is uncommon, but it is one reason sterile, graded talc and careful patient selection are important.
Pleurodesis may not work if the lung cannot fully expand, if the fluid is loculated into separate pockets, if the pleural fluid pH or glucose is low, or if the underlying disease remains very active.
The risks are different for each individual patient. A frail patient with advanced cancer may face different risks from a young person having pleurodesis for pneumothorax. Your treating team will explain the likely benefits and risks based on your diagnosis and scans.
Pleurodesis recovery usually takes days to weeks, depending on the method used and the condition being treated.
Recovery after a chemical pleurodesis through a chest tube may be shorter than recovery after a surgical approach. Recovery after VATS is often faster than open surgery, but this depends on the complexity of the disease and the patient’s general health.
During recovery, you may be advised to walk regularly, do breathing exercises, take pain medicine as prescribed, keep the wounds clean and dry, and avoid heavy lifting until cleared by your medical team. If you had VATS or another surgical approach, you may have small chest wounds that need simple dressing care.
Your team may advise avoiding NSAIDs and certain medicines unless they specifically say these are safe for you. Do not stop prescribed medicines without medical advice.
Follow-up may include a chest X-ray, a review of symptoms, a wound check, and a discussion of further treatment. If pleurodesis was done for cancer-related fluid, your care may also involve an oncologist. If it was done for a pneumothorax, follow-up focuses on lung expansions, air leak resolutions, and recurrence risks.
Seek urgent medical review if you develop a fever, worsening breathlessness, increasing chest pains, wound redness, swellings, pus, heavy bleeding, dizziness, blue lips, or a sudden worsening after your hospital discharge.
Treatment options as alternatives to pleurodesis include observation, repeated drainage, chest tube drainage, an indwelling pleural catheter, surgery for trapped lung, or the treatment of the underlying condition. These treatment options aim to remove excess fluid and protect respiratory function.
Neumark Lung & Chest Surgery Centre helps patients decide whether the pleurodesis procedure is the right treatment for them and which approach is safest for their condition.
Neumark specialises in minimally invasive thoracic surgery with a multidisciplinary approach led by Dr Harish Mithiran, senior consultant thoracic surgeon at Gleneagles and Mount Alvernia hospitals. For patients with recurrent pleural effusions, recurrent pneumothorax, malignant pleural effusions, trapped lung, or complex pleural disease, careful assessment before treatment is recommended.
If you have repeated fluid or air around the lung, or if pleurodesis has been recommended, contact Neumark for a consultation.
Pleurodesis can be done through a chest tube or as part of a surgery. Chemical pleurodesis through a chest tube is less invasive than surgical pleurodesis. VATS pleurodesis is still a surgical procedure and is usually done under general anaesthesia.
If pleurodesis is successful, the pleural space stays sealed long term. However, fluid or air can return if the pleurodesis does not fully work or if the underlying disease remains active.
Sterile talc is the most commonly used agent for chemical pleurodesis. Other agents, such as doxycycline or bleomycin, may be used in selected cases depending on local practice and the patient’s condition.
The main downsides include pain, fever, need for a chest drain, hospital stay, possible complications, and the chance that it may not work. It may also be unsuitable if the lung cannot expand fully.
Pleurodesis itself is not intended to reduce life expectancy. In cancer-related effusions, the overall outlook depends mainly on the type and stage of the cancer, not the pleurodesis procedure.
Pleurodesis can cause chest pain because it creates controlled inflammation. Pain is usually managed with medicine. Surgical pleurodesis may cause more discomfort than chemical pleurodesis via chest tube, especially in the first few days after the procedure.
