Pulmonary effusion refers to pleural effusion, which may be caused by a variety of diseases that result in excess fluid in the pleural cavity and can lead to more uncomfortable symptoms.
When patients have infectious diseases such as pleurisy, tuberculosis, pneumonia, as well as malignant tumors of the lungs, trauma, etc., it can lead to the emergence of increased hydrostatic pressure of pleural capillaries, increased vascular permeability, decreased colloid osmolality, and impeded lymphatic reflux. This in turn breaks the balance between secretion and absorption of fluid in the pleural cavity, leading to the formation of pleural effusion.
Symptoms may vary depending on the cause of pleural effusion, but usually symptoms such as chest pain, cough and dyspnea are present.
It is recommended that patients actively cooperate with doctors to improve relevant examinations, clarify the cause of the disease and take targeted treatment measures.
