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 ...
Because the transdiaphragmatic lymphatic channels are larger in diameter on the right, the pleural effusion is classically on the right side. The causes of the ascites and pleural effusion are poorly understood. [1] Atypical Meigs syndrome, characterized by a benign pelvic mass with right-sided pleural effusion but without ascites, can also occur.
Pleural plaques are patchy collections of hyalinized collagen in the parietal pleura. [2] They have a holly leaf appearance on X-ray . [ 1 ] They are indicators of asbestos exposure, and the most common asbestos-induced lesion. [ 3 ]
A technique called pleurodesis can be used to intentionally create scar tissue within the pleural space, usually as a treatment for repeated episodes of a punctured lung, known as a pneumothorax, or for pleural effusions caused by cancer. While this procedure usually generates only limited scar tissue, in rare cases a fibrothorax can develop. [6]
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 ...
Definitive diagnosis is necessary to avoid unnecessary treatment and exclude more serious diagnoses (for example, haemoptysis, pleural effusion or cancer). Overall treatment for pulmonary endometriosis is surgical, with subsegmentectomy. Preserving lung parenchyma is a priority while removing macroscopic signs of pathological tissue. [5]
An official diagnosis is made by identifying excess serous fluid in at least one space (ascites, pleural effusion, of pericardial effusion) accompanied by skin edema (greater than 5 mm thick). A diagnosis can also be made by identifying excess serous fluid in two potential spaces without accompanying edema.
Malignant pleural effusion is a condition in which cancer causes an abnormal amount of fluid to collect between the thin layers of tissue lining the outside of the lung and the wall of the chest cavity. [1] Lung cancer and breast cancer account for about 50-65% of malignant pleural effusions.
