However, this may not always be visibly evident if the outer wall is rigid like within the cranial or thoracic cavities. Edema, also spelled oedema, plural edemas, or edemata, in medicine, an abnormal accumulation of watery fluid in the intercellular spaces of connective tissue. Inflammation of the pericardium (pericarditis) is one of the main reasons for a pericardial effusion. Inflammation of the membranous linings of the body cavities is one of the main causes of effusion. Pleural fluid analysis. Surgical removal of the adenoids (adenoidectomy) may also be useful and can help to restore eustachian tube function. edema (ĭdē`mə), abnormal accumulation of fluid in the body tissues or in the body cavities causing swelling or distention of the affected parts.Edema of the ankles and lower legs (in ambulatory patients) is characteristic of congestive heart failure, but it can accompany other conditions, including obesity, diseased leg veins, kidney disease, cirrhosis of the liver, anemia, … the excessive accumulation of fluid in the organs and intercellular tissue spaces of the body. However, sometimes blood or pus can be mixed with the fluid and collect in these cavities. This fluid is essentially an ultrafiltrate of serum but also contains small amounts of protein. The quantity of accumulated fluid and the risk of a cardiac tamponade will also be taken into consideration. The synovial fluid is secreted by the synovial membrane that lines the joint surfaces. What is the medical term meaning abnormal accumulation of fluid in a saclike cavity? Edemas are classified according to the various conditions that can impair the drainage and retention of fluids. It is mainly linked to liver disorders (hepatic) such as cirrhosis but can be due to other conditions that do not involve the liver (non-hepatic). A small amount of fluid is normally present in this spaces and is known as pericardial fluid. The excess fluid that accumulates within the body cavities during effusion can be broadly classified into two types. The space between two joints contains a small space, which contains synovial fluid. Surgical intervention may involve a myringotomy where a small opening is created in the ear drum and the fluid is then drained. If there is an excessive collection of fluid, it may compress the heart and this is known as a cardiac tamponade. Joint effusion occurs when excessive fluid accumulates in the space between the joints. Inflammatory conditions are not the cause of transudate fluid accumulation. Majority of ascites cases is due to liver disease (hepatic causes) such as : The more common non-hepatic causes includes peritonitis, pancreatitis and congestive heart failure. Most commonly, the legs or arms are affected. In the inflammation process, the blood flow to the inflamed area increases and the blood vessels become more porous allowing large amounts of fluid from the blood, along with certain blood proteins, to exit the blood vessels and pass into the cavities. The main causes of effusion of the brain are hydrocephalus and subdural effusion. The causes of effusion depend on the site of effusion. acute respiratory failure: Term. Accumulation of fluid in the body cavities may lead to compression of nearby tissues. Exudate may result from pulmonary infarction, trauma, tumor, or infection. Medicine An excessive accumulation of serous fluid in tissue spaces or a body... Oedemata - definition of oedemata by The Free Dictionary ... an abnormal accumulation of fluid in the tissue spaces, cavities, or joint capsules of the body, causing swelling of the area. Joint deformity and nodules may be a consequence of the underlying disease that also causes an effusion. If the fluid affects the function of the heart, it's called cardiac tamponade.
