Sometimes referred to as ‘water on the lungs’, pleural effusion is a condition where the layers of the pleura outside your lungs have excess fluid build-up.
The pleura are thin membranes that usually contain a small amount of fluid that lubricates and facilitates breathing and lines the inside of the chest cavity and your lungs.
The excess fluid build-up can be either protein-rich (exudative) or protein-poor (transudative). These are the two categories that can help your doctor to find the cause of this condition.
You may not experience the symptoms of pleural effusion at first or may experience mild symptoms. Sometimes you may not experience the symptoms at all.
Symptoms of this condition depend on the amount of fluid build-up and how fast it builds. It also depends on the underlying condition which has caused the fluid build-up. You may experience:
You may experience orthopnea, a condition where you feel shortness of breath while lying down. When you have this, you will feel better when you sit up or stand.
Problem in breathing, especially shortness of breath may make you feel more tired than usual as it may cause difficulty in sleeping at night.
Ensure you get medical help immediately when you experience such symptoms.
When fluid leaks into the pleural space, it causes transudative pleural effusion. This is a result of excessive pressure in the blood vessels or a low blood protein count. The different causes of exudative effusion are blocked blood vessels or lymph vessels, infection, inflammation, injury to lungs, and tumors.
You may also suffer from this condition due to radiation therapy, abdominal surgery, and certain medications. It may also occur with several types of cancer including lymphoma, lung, and breast cancer. In some cases, the fluid collected itself can be cancerous.
Men and women are at risk of developing pleural effusion due to the following factors:
There are also certain factors that may contribute to putting you at increased risk of pleural effusion:
When you experience the symptoms of pleural effusion, ensure you visit the doctor’s clinic immediately and get medical attention.
Your doctor will conduct a physical examination and may order a few tests to diagnose this condition.
Following are the tests that your doctor may order:
Your doctor may also order a few blood tests like:
Your treatment depends on the test results and the underlying cause of the pleural effusion. A minor pleural effusion may resolve on its own.
Your doctor may prescribe diuretics and other heart failure medications if congestive heart failure is the reason for this condition. For malignant effusion or cancerous fluid build-up, your doctor may suggest radiation therapy, chemotherapy, or a drug is inserted within the chest.
Thoracentesis may be done to remove extra fluid surrounding the lungs. It is done by inserting a hollow needle in the middle of your ribs into the pleural cavity.
Your doctor may use a sclerosing agent occasionally if this condition is uncontrollable or recurs due to cancer. A sclerosing agent is a type of drug that causes scarring purposefully. This drug is instilled into your pleural cavity via tube thoracostomy to create fibrosis of the pleura, also called pleural sclerosis.
Pleural sclerosis is 50 % successful in preventing the recurrence of pleural effusion. The expert will use sclerosing agents like tetracycline, talc, and doxycycline for pleural sclerosis.
If this condition cannot be managed through pleural sclerosis or drainage, your doctor may order surgery.
Pleural effusion surgery can be done in 2 ways:
For this surgery, your doctor may make a single incision of approximately 6 to 8 inches in your chest. Typically, doctors recommend open thoracic surgery when there is a presence of infection with pleural effusion.
This surgery is performed to remove all the fibrous tissues and treat the infection present on the pleural space. After the surgery, the patient will require chest tubes for 2 days to 2 weeks approximately to get rid of fluid completely.
It is a minimally invasive surgery that is completed through 1 to 3 small cuts or incisions in your chest.
This surgery can effectively manage pleural fluid build-ups that may develop again due to cancer or are difficult to drain. The surgeon may insert antibiotic or sterile talc at the time of surgery to prevent a recurrence.
After the surgery, your doctor will carefully examine your condition to decide on a suitable treatment option for you. Your doctor may also discuss the benefits and possible risks from the suggested treatment.
Your doctor will suggest a few lifestyle changes for pleural effusion that you must follow. Your doctor may suggest:
Apart from these lifestyle changes, your doctor may also suggest a few more that may be suitable for your particular condition. Ensure you follow it properly. In case you have any doubts or face any issues, visit the doctor’s clinic immediately.
