PULMONARY SEQUESTRATION Meaning and
Definition
-
Pulmonary sequestration is a rare congenital anomaly characterized by the presence of nonfunctioning lung tissue that is separated from the normal lungs and receives its blood supply from systemic circulation rather than the pulmonary circulation. This condition occurs during fetal development when abnormal lung tissue fails to connect with the tracheobronchial tree.
The nonfunctioning lung tissue in pulmonary sequestration is typically located within the lungs or adjacent to the lungs. It is disconnected from the bronchial tree, which is responsible for supplying oxygen to the lungs, and instead, it receives blood supply from systemic arteries originating from the descending aorta or other arteries within the chest cavity. As a result, the blood flow to this abnormal lung tissue is different from the normal lung tissue, and it is not exposed to the process of gas exchange as seen in healthy lungs.
Pulmonary sequestration can be classified into two types: intralobar and extralobar. In intralobar sequestration, the abnormal lung tissue is located within the same lobe as the normal lung tissue, and it is usually contained within the pleural envelope. Conversely, in extralobar sequestration, the abnormal lung tissue is located outside the pleural envelope, usually in a separate lobe, and it may present with its own pleura.
Symptoms of pulmonary sequestration can vary, but they commonly include recurrent pneumonia, respiratory distress, and cough. Diagnosis is typically made by imaging studies such as computed tomography (CT) scans or magnetic resonance imaging (MRI). Treatment options include surgical removal of the abnormal lung tissue or embolization of the feeding blood vessels.
In conclusion, pulmonary sequestration is a rare congenital lung anomaly characterized by nonfunctioning lung tissue that is disconnected from the normal lungs

Etymology of PULMONARY SEQUESTRATION
The word "pulmonary" derives from the Latin word "pulmo", meaning "lung". It entered the English language in the early 17th century. The word "sequestration" also has Latin roots, coming from the Latin verb "sequestrare", meaning "to set apart" or "to separate". In medical terminology, "sequestration" refers to the abnormal development or presence of certain tissues or organs that are separate from their normal location or blood supply.
Therefore, "pulmonary sequestration" refers to a medical condition characterized by the abnormal development or presence of lung tissue that is separated or set apart from the normal lung tissue.
