What is Chyliform effusion?
Pseudochylothorax, also known as chyliform effusion rich in cholesterol crystals, is a rare entity that sometimes occurs in long-standing rheumatoid arthritis (RA) and is usually associated with thickened pleura.
What is a chylous pleural effusion?
Abstract. Objectives: Chyle is a noninflammatory, lymphocyte-predominant fluid that may cause a pleural effusion as a consequence of thoracic duct leakage into the pleural space.
What causes Chylous effusion?
The most common cause of non-traumatic chylous effusion is a malignancy, such as lymphoma or metastatic carcinoma (5,6). Other causes of non-traumatic chylous effusion include idiopathic chylous effusion, a congenital anomaly, protein-losing enteropathy, and TB (6,7).
What are the 2 classifications of effusion?
There are two types of pleural effusion:
- Transudative pleural effusion is caused by fluid leaking into the pleural space.
- Exudative effusion is caused by blocked blood vessels or lymph vessels, inflammation, infection, lung injury, and tumors.
What is the difference between chylothorax and pleural effusion?
Chylothorax is a rare cause of pleural effusion due to the extravasation of chyle from the thoracic duct or its tributaries. Neonatal chylothorax has an incidence of 1 in 5775 to 1 in 100 000 live births but can be considered the most common form of pleural effusion encountered in the perinatal period.
Is chylous effusion exudative?
Chylous pleural effusions are typically described as exudative lymphocytic pleural effusions with a milky appearance. However, biochemical parameters of chylous pleural effusions have been inadequately analyzed.
What is chyle leakage?
Chyle leak was defined as output of milky-colored fluid from a drain, drain site, or wound on or after postoperative day 3, with a triglyceride content ≥110 mg/dL (≥1.2 mmol/L).
What is effusion in chemistry?
Effusion occurs when a gas passes through an opening that is smaller than the mean free path of the particles, that is, the average distance traveled between collisions. Effectively, this means that only one particle passes through at a time.
What are the types of effusion?
Is chylothorax transudate or exudate?
Typically, chylothorax is a type of exudative pleural effusion which is rich in triglycerides or shows the presence of chylomicrons.
Is chylothorax a type of pleural effusion?
Chylothorax is a rare but serious condition, as it signals leakage of the thoracic duct or one of its tributaries. There are many treatments, both surgical and conservative. About 2–3% of all fluid collections surrounding the lungs (pleural effusions) are chylothoraces.
What is hemothorax effusion?
A hemothorax (plural: hemothoraces), or rarely hematothorax, literally means blood within the chest, is a term usually used to describe a pleural effusion due to accumulation of blood. If a hemothorax occurs concurrently with a pneumothorax it is then termed a hemopneumothorax.
What is in chylous fluid?
Chyle (KYE-ul) is made of lymph and tiny fat droplets. Lymph (LIMF) is a clear fluid that carries fats and proteins, helps fight germs, and keeps the body’s fluid levels normal. Lymph vessels take chyle to the bloodstream.
What is a chylous sample?
Chylous ascites (CA) is a rare form of ascites that results from the leakage of lipid-rich lymph into the peritoneal cavity. This usually occurs due to trauma and rupture of the lymphatics or increased peritoneal lymphatic pressure secondary to obstruction.
