Term: Bronchoalveolar Lavage (BAL)
Definition: Bronchoalveolar Lavage (BAL) is a medical procedure in which a bronchoscope is used to introduce a sterile fluid into a specific part of the lung, which is then collected for analysis. This technique helps in diagnosing and studying lung diseases by retrieving cells, microorganisms, and other substances from the lower respiratory tract.
Phonetic Pronunciation: (bron-koh-al-VEE-oh-lar luh-VAHJ)
Etymological Origin: The term originates from Latin and Greek roots: broncho- (from Greek bronchos, meaning windpipe), alveolar (from Latin alveolus, meaning small cavity or air sac), and lavage (from French laver, meaning to wash). Together, the term describes the washing of the bronchi and alveoli.
Significance in Asbestos Context: BAL is significant in the field of asbestos because it is a minimally invasive method to detect asbestos bodies and fibers in the lungs. It provides valuable information about the extent of asbestos exposure and the presence of inflammatory cells, which can indicate diseases like asbestosis or mesothelioma. BAL findings can also support clinical diagnoses and serve as evidence in asbestos-related litigation by confirming exposure and its effects on lung health.
Synonyms or Related Terms: Lung lavage, pulmonary lavage, bronchoscopy with lavage.
Example Sentence: "Bronchoalveolar lavage revealed the presence of asbestos bodies in the patient's lungs, confirming significant occupational exposure to asbestos."
