Sequestration
Sequestration (pronunciation: /ˌsiːkwɪˈstreɪʃən/ or /ˌsɛkwɪˈstreɪʃən/) is a medical term that refers to the isolation of a portion of tissue or organ due to a variety of causes. The term is derived from the Latin word "sequestrare", which means "to set aside".
Definition
Sequestration in medicine refers to the process where a portion of the body becomes isolated from the rest due to injury, disease, or other medical conditions. This can occur in various parts of the body, such as the lungs, liver, or bones. The sequestered area may develop its own blood supply, separate from the body's main circulatory system.
Causes
Sequestration can be caused by a variety of factors, including infection, inflammation, trauma, or surgery. It can also occur as a result of certain diseases, such as sickle cell disease or cystic fibrosis.
Types
There are several types of sequestration, including:
- Pulmonary sequestration: This occurs when a portion of lung tissue is not connected to the rest of the lung's airway system.
- Splenic sequestration: This is a serious complication of sickle cell disease where the spleen traps a large number of red blood cells.
- Bone sequestration: This refers to a piece of dead bone that has become separated from the rest of the bone during the process of necrosis.
Treatment
Treatment for sequestration depends on the location and cause of the condition. It may involve surgery to remove the sequestered tissue, antibiotics to treat any underlying infection, or other treatments as appropriate.
