Pleural empyema is a collection of pus in the pleural cavity caused by microorganisms, usually bacteria. [1] Often it happens in the context of a pneumonia , injury, or chest surgery. [ 1 ] It is one of the various kinds of pleural effusion .
An empyema (/ ˌ ɛ m p aɪ ˈ iː m ə /; from Ancient Greek ἐμπύημα (empúēma) 'abscess') is a collection or gathering of pus within a naturally existing anatomical cavity. The term is most commonly used to refer to pleural empyema , [ 1 ] which is empyema of the pleural cavity .
Blood that remains within the pleural space can become infected, and is known as an empyema. [3] It occurs in 3–4% of traumatic cases, [ 9 ] and 27-33% of retained hemothoraces. [ 37 ] It is more likely in people who develop shock, had a contaminated pleural space during the injury, persistent bronchopleural fistulae , and lung contusions.
Pleurisy Pleural linings and space (marked in blue) The pleural space can be invaded by fluid, air, and particles from other parts of the body, which fairly complicates diagnosis. [ 12 ] [ 13 ] Viral infection ( coxsackie B virus , HRSV , CMV , adenovirus , EBV , parainfluenza , influenza , COVID-19 ) is the most common cause of pleurisy.
A parapneumonic effusion is a type of pleural effusion (accumulation of fluid in the pleural cavity) that arises as a result of a pneumonia, lung abscess, or bronchiectasis. [1] There are three types of parapneumonic effusions: uncomplicated effusions, complicated effusions, and empyema. Uncomplicated effusions generally respond well to ...
These imaging techniques can detect fibrothorax and pleural thickening that surround the lungs. [7] The presence of a thickened peel with or without calcification are common features of fibrothorax when imaged. [3] CT scans can more readily differentiate whether pleural thickening is due to extra fat deposition or true pleural thickening than X ...
Pleural effusion obliterates the pleural vacuum and can collapse the lung (due to hydrostatic pressure), impairing ventilation and leading to type 2 respiratory failure. The condition can be treated by mechanically removing the fluid via thoracocentesis (also known as a "pleural tap") with a pigtail catheter , a chest tube , or a thoracoscopic ...
A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
