Pleural surgery and pleurodesis (Pleural surgery / pleurodesis)
Procedures on the lining of the lung to stop fluid or air building up around it, including pleurodesis (sealing the space) and removing or sampling the lining.

In short
- Pleural procedures treat repeated fluid or air around the lung that causes breathlessness; pleurodesis seals the space so it cannot refill.
- For cancer-related fluid, an indwelling pleural catheter is often a first choice; talc pleurodesis works best when the lung can fully re-expand.
- These procedures relieve symptoms and control the build-up but do not, on their own, treat an underlying cancer.
- The approach (drain at the bedside versus keyhole surgery) and the anaesthetic depend on the cause, your fitness and how well the lung re-expands.

What is pleural surgery and pleurodesis?
The pleura is the thin lining around the lungs, with a small space between its two layers. Problems happen when fluid (a pleural effusion) or air (a pneumothorax) repeatedly builds up in this space and presses on the lung, causing breathlessness.
Pleurodesis is a procedure that sticks the lung to the chest wall so the space can no longer fill. It is usually done by putting sterile graded talc into the space, either through a chest drain or at a keyhole operation (VATS). Other pleural procedures include taking biopsies of the lining, removing part of the lining (pleurectomy), and placing a thin tube (an indwelling pleural catheter) that lets fluid be drained at home.
The right option depends on the cause. For fluid caused by cancer, current UK guidance often favours an indwelling pleural catheter as a first choice, with talc pleurodesis suitable when the lung can fully re-expand. For recurrent air leaks (pneumothorax), keyhole surgery with treatment of the lining lowers the chance of it happening again. These procedures control the problem and ease symptoms; for cancer-related fluid they do not treat the cancer itself.
Types & techniques
There isn't one single operation. The right approach depends on you — which is something to discuss with your surgeon.
Common options for fluid around the lung
| Option | Where | Often used when |
|---|---|---|
| Talc pleurodesis | Ward or theatre | Lung re-expands fully and you can tolerate the procedure |
| Indwelling catheter | Often day case | Cancer fluid, or lung does not fully re-expand |
| Simple drainage | Ward | First episode or to relieve symptoms quickly |
The best option depends on the cause, how well the lung re-expands and your overall health. Your team will explain the trade-offs for you.
Preparing for your surgery
- Ask what is causing the fluid or air, and why this particular procedure is being recommended.
- Expect scans (such as a chest X-ray, CT or ultrasound) to check the lung can re-expand and to guide the procedure.
- Tell the team about all medicines, especially blood thinners, and ask which to pause and when.
- For a general anaesthetic (VATS), follow fasting instructions; for a bedside drain, ask what to expect.
- If you may have an indwelling catheter, ask who will help drain it at home and how it is cared for.
- Arrange a lift home and some help for the first days, depending on the procedure.
What happens
What happens depends on the procedure. For talc pleurodesis through a chest drain, the space is first drained, then sterile graded talc is introduced; this can cause chest discomfort and a temporary fever, and the drain stays in until the lung has sealed.
For keyhole (VATS) pleurodesis, you have a general anaesthetic and the surgeon treats the lining and applies talc through small cuts, often taking biopsies. For an indwelling pleural catheter, a thin tube is tunnelled under the skin under local anaesthetic so fluid can be drained at home over time.
Good pain relief matters, and a physiotherapist may help with breathing. You are monitored afterwards, and chest X-rays check how the lung is re-expanding before any drain comes out.
Is this operation right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- The lung cannot fully re-expand to reach the chest wall, making pleurodesis unlikely to work (a catheter may be better).
- You are too unwell to tolerate a general anaesthetic when keyhole surgery is proposed.
- Active infection or bleeding risk that is not yet controlled.
- The cause is better treated another way (for example, treating the underlying cancer or heart failure).
- A simple, self-limiting first episode that does not yet need a permanent solution.
Delay surgery if…
- You have an active infection or are systemically unwell, unless the procedure is for that infection.
- Blood-thinning or other medicines need adjusting.
- Imaging has not yet confirmed whether the lung re-expands.
- The underlying diagnosis is unclear and biopsies or more tests are needed.
- Practical home support for a catheter is not yet in place.
Alternatives to discuss
- Simple chest drainage to relieve symptoms without sealing the space.
- An indwelling pleural catheter instead of pleurodesis, especially for cancer fluid.
- Treating the underlying cause (for example heart failure or the cancer itself).
- Watchful waiting for a small, first or self-limiting problem.
- Surgery (pleurectomy) for recurrent pneumothorax in suitable people.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Anaesthetic choices
The safest option depends on the operation, your health, the facility and your surgeon/anaesthetist. Ask what is planned and why.
Benefits
- Can ease breathlessness by stopping fluid or air pressing on the lung
- Reduces the chance of fluid or air building up again
- An indwelling catheter can let fluid be managed at home, with fewer hospital visits
- Biopsies taken at the same time can help diagnose the cause
- Keyhole treatment of the lining lowers the recurrence risk after pneumothorax
Risks & complications
- Chest pain or discomfort, especially during and after talc pleurodesis
- A temporary fever after talc
- Discomfort at the drain or catheter site
- Pleurodesis not fully working, so fluid or air returns
- Infection at the catheter site or in the pleural space
- Bleeding into the pleural space
- The lung not fully re-expanding, so pleurodesis is less likely to work
- Blockage or displacement of an indwelling catheter
- A serious reaction to talc affecting the lungs (more linked to ungraded talc, which is why graded talc is used)
- Significant bleeding needing further treatment
- Injury to the lung or nearby structures
- Serious breathing difficulty needing intensive care
The biggest factor in whether pleurodesis works is whether the lung can fully re-expand to touch the chest wall — if it cannot, sealing the space is less likely to succeed and a catheter may be better. Graded (sterile, sized) talc is used because ungraded talc has been linked to rare but serious lung reactions. For cancer-related fluid, remember these procedures treat the symptom, not the cancer. Ask your team which option best fits your situation and why.
Published figures to discuss
Success and complication rates vary widely with the cause, the procedure and whether the lung can fully re-expand. Robust single figures are not meaningful across such different situations, so the points below are deliberately cautious and qualitative.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Pleurodesis failure (fluid or air returns) | Varies widely; clearly more likely when the lung does not fully re-expand | Full lung re-expansion to the chest wall is the main factor in success; exact rates depend on cause and technique. | Updates on BTS Statement on Pleural Disease and Procedures 2023 (PMC)pmc.ncbi.nlm.nih.govSource-linked context |
| Recurrence of pneumothorax after surgical treatment of the lining | Lower after VATS surgery than after a chest drain alone | Treating the lining surgically reduces, but does not abolish, the chance of another pneumothorax. | Guide sourcesClinical context |
| Serious talc-related lung reaction | Rare, and linked mainly to ungraded talc | Graded (sized) talc is used in the UK specifically to reduce this risk. | Updates on BTS Statement on Pleural Disease and Procedures 2023 (PMC)pmc.ncbi.nlm.nih.govSource-linked context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
Recovery — what to expect, and when
Recovery depends on the procedure and the underlying condition. A bedside catheter procedure may be a day case, while keyhole surgery usually means a few days in hospital. Breathlessness often improves once the fluid or air is controlled, though tiredness can linger.
- Chest soreness and a temporary fever after talc
- Tiredness for a week or two
- Discomfort at the drain or catheter site
- Gradual easing of breathlessness as the build-up is controlled
- Needing regular catheter drainage at home for a while, if you have one
Aftercare
- Take pain relief as advised, as the chest can be sore after talc.
- Keep the catheter or drain site clean and dry and follow the care instructions exactly.
- If you have an indwelling catheter, follow the agreed drainage schedule and technique.
- Do your breathing exercises and stay gently active.
- Watch for signs of infection at the site or feeling generally unwell.
- Report increasing breathlessness, which could mean fluid or air is returning.
- Attend follow-up so the team can check the procedure has worked and review the cause.
- Pain relief understood and collected
- Catheter care instructions and supplies, if you have one
- Who will help with home drainage arranged
- Help at home for the first days
- Lift home arranged where relevant
- Clinic and out-of-hours contact numbers saved
- Follow-up appointment and any results discussion arranged
Scars and how they heal
Keyhole (VATS) surgery leaves one or a few small scars between the ribs. A chest drain or indwelling catheter leaves a small puncture or tunnel-site scar; a tunnelled catheter has a short scar where it passes under the skin. Marks usually fade over months, though some altered sensation near the site is common.
⚠ Get urgent help if…
- Worsening or sudden breathlessness (fluid or air may be returning)
- Chest pain that is severe or getting worse
- Fever, chills or feeling generally unwell after the first day or two (possible infection)
- Redness, swelling, warmth or discharge at the drain or catheter site
- Coughing up blood
- The catheter coming loose, leaking heavily or stopping draining
- Feeling faint or a fast heartbeat
Who to contact: your surgeon or clinic first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your surgeon gives you.
Results & realistic expectations
A good result means the fluid or air no longer builds up enough to cause breathlessness, and any breathlessness improves. For pleurodesis, success is judged over days to weeks and depends largely on whether the lung re-expanded fully. For an indwelling catheter, success means symptoms are controlled with manageable home drainage, and sometimes the catheter can later be removed if fluid stops.
Where biopsies were taken, the laboratory results help confirm the cause. These procedures control the pleural problem and ease symptoms; for cancer-related fluid they do not treat the cancer, which is managed separately by the wider team.
How long the benefit lasts depends on the cause. Pleurodesis aims to seal the space permanently, but it can fail or partly fail, and fluid or air may return and need further treatment. Indwelling catheters can manage fluid for months and sometimes lead to the space sealing on its own. For cancer-related fluid, control depends partly on how the underlying cancer responds to its own treatment.
Combining with other procedures
Pleural procedures are often combined with biopsies to diagnose the cause, and with drainage to relieve symptoms first. For cancer, they sit alongside treatment of the cancer itself by the oncology team. Sometimes more than one approach is used over time, for example a catheter followed by pleurodesis.
Follow-up & long-term care
You will usually be reviewed to check the procedure has worked, to discuss any biopsy results and to manage an indwelling catheter if you have one. Report returning breathlessness, site infection or feeling unwell between appointments. For cancer-related fluid, follow-up is coordinated with your cancer team.
- Follow the agreed catheter drainage schedule and care if you have one
- Keep follow-up appointments to check the result and the underlying cause
- Report returning breathlessness or site problems promptly
- Keep up gentle activity and breathing exercises during recovery
Revision and secondary surgery reality
- Pleurodesis can fail or only partly work, and the fluid or air may return and need a repeat or a different procedure.
- An indwelling catheter may need to stay long term, be replaced, or occasionally be removed if fluid stops.
- More than one approach is sometimes used over time as the situation changes.
- For cancer-related fluid, control also depends on how the cancer responds to its own treatment.
Ask your surgeon for their own revision rate, what counts as a revision, and what is included in the written aftercare policy.
What good aftercare looks like
- A clear, written pain-relief plan, as the chest can be sore after talc.
- Practical catheter training and supplies, with a community or hospital contact for drainage.
- A named contact and out-of-hours route for breathlessness, infection or catheter problems.
- Follow-up imaging or review to confirm the build-up is controlled.
- Coordination with the cancer or medical team treating the underlying cause.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- The procedure chosen (bedside pleurodesis, keyhole surgery or an indwelling catheter)
- Whether a general anaesthetic and theatre are needed
- Surgeon, physician and anaesthetist fees
- Length of hospital stay and any high-dependency care
- The catheter and ongoing drainage supplies, if used
- Imaging to plan the procedure and check the lung re-expands
- Laboratory analysis of any fluid or biopsies, and follow-up
- Operator and any anaesthetist fees
- Theatre, ward and any high-dependency costs
- Catheter and home-drainage supplies, if relevant
- Imaging and laboratory (fluid and biopsy) analysis
- Length-of-stay assumptions and what happens if you stay longer
- Follow-up appointments and catheter management
- What is covered if the procedure does not work or a complication occurs
On the NHS? Pleural procedures are routinely available on the NHS when clinically indicated; private care may be used for speed or choice of specialist, not because they are unavailable on the NHS.

Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Not explaining that pleurodesis may fail, especially if the lung does not fully re-expand.
- Not making clear the procedure treats the build-up, not an underlying cancer.
- No discussion of the catheter option versus pleurodesis and their trade-offs.
- Underplaying the pain and fever that can follow talc pleurodesis.
- No plan or support arranged for caring for a catheter at home.
Marketing red flags
- Implying pleurodesis treats or cures the underlying cancer.
- Presenting the procedure as usually not painful or guaranteed to work.
- Not mentioning that lung re-expansion strongly affects success.
- No discussion of the indwelling catheter alternative.
- Pushing surgery without confirming the cause with biopsies or imaging.
Choosing a surgeon safely
- Check your surgeon is on the GMC Specialist Register for this area.
- Make sure they practise at a CQC-registered location, and look for membership of bodies like BAAPS or BAPRAS.
- You're entitled to a two-stage consent process with time to reflect (a cooling-off period). The surgeon who will operate must consent you — not a salesperson.
- Be wary of pressure: time-limited offers, discounts or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including aftercare and any revision — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good surgeon will welcome every one of these.
- What is causing the fluid or air, and why this procedure for me?
- Will my lung fully re-expand, and how does that affect which option is best?
- Would an indwelling catheter suit me better than pleurodesis, or the other way round?
- How will pain and any fever be managed, and how long will a drain stay in?
- What happens if the fluid or air comes back?
- If a cancer is the cause, how does this fit with my cancer treatment?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the surgeon who carries out my operation, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this operation not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
