Pronunciation: [plˈɜːɹə͡ʊdsˌiz] (IPA) 
Pleurodesis is a medical term used to describe a procedure in which the lining of the lungs is intentionally irritated to create adhesions, essentially gluing the layers of the lung together. The spelling of the word is phonetic, with the "pleuro" portion coming from the Greek word for "lung," while "desis" is from the Greek "to bind together." In IPA phonetic transcription, the word would be pronounced /plʊˈroʊdɛsɪs/.
Pleurodesis is a medical procedure aimed at treating recurrent or malignant pleural effusions, which is the accumulation of excess fluid between the layers of the membrane covering the lungs (pleura). This condition can cause difficulty in breathing and other respiratory symptoms.
During a pleurodesis procedure, a substance is introduced into the pleural space to create inflammation and adhesion between the layers of the pleura. This effectively prevents further fluid accumulation and helps to permanently seal off the space. The substance used may vary, but commonly includes talc, doxycycline, or bleomycin.
The procedure can be performed using different techniques such as video-assisted thoracoscopic surgery (VATS) or through a chest tube. In VATS, small incisions are made, and a camera is inserted to visualize the pleural space, allowing for precise administration of the substance. When a chest tube is used, the substance is typically delivered through the tube, and the patient may need to change positions to ensure effective distribution.
Pleurodesis can be carried out under local or general anesthesia, depending on the patient's condition and the chosen technique. Following the procedure, patients may experience pain, inflammation, or discomfort in the chest, which can be managed with pain medications.
Pleurodesis is generally considered a safe procedure, but there is a risk of complications, such as infection, bleeding, or damage to surrounding structures. Patients are closely monitored during and after the procedure to identify and address any potential complications.
The word "pleurodesis" comes from the combination of two Greek roots: "pleura" and "desis".
- "Pleura" (πλευρά) in Greek means "rib". In medical terminology, it specifically refers to the two-layered membrane that surrounds the lungs and lines the thoracic cavity. The pleura helps protect and lubricate the lungs during breathing.
- "Desis" (δέσις) in Greek means "binding" or "fastening". It is derived from the verb "dein" (δείν), which means "to bind" or "to tie".
Therefore, the term "pleurodesis" literally translates to "binding of the pleura" or "fastening of the pleura".
