Pulmonary hypertrophy is a condition in which some parts of the body become swollen, enlarged and painful because of a lung disease. Common pulmonary hypertrophy diseases include pulmonary hypertrophic osteoarthropathy. So, what tests should be done for patients with pulmonary hypertrophy? The following is a brief introduction: 1. CT examination of bones, joints and soft tissues: CT examination of bones, joints and soft tissues is a method of examining bones, joints and soft tissues through CT. It is mainly for injuries and diseases of bones, joints and soft tissues. It is suitable for patients who suffer from bone, joint and soft tissue diseases. 2.Joint cavity fluid examination: The plasma membrane cavities in the human body are pleural cavity, pericardial cavity, peritoneal cavity, joint cavity, scrotal sheath cavity, etc.. Under normal conditions, there is only a small amount of fluid in the cavity, which acts as a synovial fluid. However, in pathological conditions, there can be a large amount of fluid in the cavity, called plasma cavity effusion, such as pleural effusion, ascites, pericardial effusion, scrotal sphincter effusion, joint cavity effusion, etc. Due to the different etiology of effusion, it can be divided into two kinds of fluid, leakage and exudate, and their various components and properties are obviously different. The significance of examining the amount, appearance, acidity, relative density, protein, glucose and microscopic examination of various effusions is to distinguish the nature of the effusion, determine whether it is leakage or exudate, and then find out the etiology and carry out treatment.
