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 ...
Vascular causes of hemothorax include rupture of the descending aorta, in which case it initially involves the left pleural and mediastinal area due to the close vicinity of the pleural cavity. Rarely, a rupture of the thoracic aorta can result in a hemothorax, but the bleeding usually occurs in the pericardial space. [ 8 ]
Hydrothorax is the synonym of pleural effusion in which fluid accumulates in the pleural cavity. This condition is most likely to develop secondary to congestive heart failure, following an increase in hydrostatic pressure within the lungs. More rarely, hydrothorax can develop in 10% of patients with ascites which is called hepatic hydrothorax ...
Hepatic hydrothorax is a rare form of pleural effusion that occurs in people with liver cirrhosis. It is defined as an effusion of over 500 mL in people with liver cirrhosis that is not caused by heart, lung, or pleural disease. It is found in 5–10% of people with liver cirrhosis and 2–3% of people with pleural effusions.
A chest X-ray will show fluid in the alveolar walls, Kerley B lines, increased vascular shadowing in a classical batwing peri-hilum pattern, upper lobe diversion (biased blood flow to the superior parts instead of inferior parts of the lung), and possibly pleural effusions. In contrast, patchy alveolar infiltrates are more typically associated ...
The most common cause is injury to the chest from blunt force or surgery on the heart or chest. Hemothorax also can occur in people with lung or pleural cancer. Hemothorax can put pressure on the lung and force it to collapse. It also can cause shock, a state of hypoperfusion in which an insufficient amount of blood is able to reach the organs.
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.
Fibrothorax may also occur without a clear underlying cause, in which case it is known as idiopathic fibrothorax. 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 ...
