The specific survival time of hydrocele, or pericardial effusion, is related to the severity of the disease and the treatment of the primary disease, and there is no specific clinical survival time statistics. Most patients have a small amount of pericardial effusion, which may be caused by pericarditis or heart disease. After active treatment of the primary disease, the small amount of pericardial effusion can be gradually reduced and absorbed, which does not affect the patient’s life expectancy; if the primary disease is prolonged, it may lead to chronic pericardial effusion, which has a certain impact on heart function, and the specific survival time is related to the primary disease; if the patient is suffering from heart failure or tumor causing pericardial If the patient has a large amount of pericardial effusion due to heart failure or tumor, it will significantly shorten the patient’s life expectancy and may even lead to pericardial compression, which in turn may cause sudden death. Patients with pericardial effusion should have their primary disease identified and treated aggressively, and patients with pericardial pressure need to be treated with timely fluid extraction to save their lives.
