bronkoalveolaarinen

Bronkoalveolaarinen is an adjective in Finnish medical terminology used to denote relation to both the bronchioles and the alveolar compartments of the lung. It is commonly applied to anatomical regions, pathological processes, and diagnostic procedures that involve the small airways and the air-exchanging units of the lung.

In anatomy and physiology, bronkoalveolaarinen refers to the portions of the respiratory tract that include the bronchioles and the alveolar spaces, i.e., the gas exchange units of the lung. In radiology and pathology, the term is used for patterns and diseases that affect both bronchiolar and alveolar structures. Examples include descriptions of infiltrates or inflammatory processes that involve multiple parts of the bronchioloalveolar unit.

In oncology, bronkoalveolaarinen karsinooma refers to a historical term for a subset of lung adenocarcinoma known as bronchioloalveolar carcinoma (BAC). This term is largely outdated in modern classifications, which distinguish adenocarcinoma in situ and minimally invasive adenocarcinoma based on invasion and histology.

In bronchoscopy and diagnostics, bronkoalveolaarainen lavage, or bronchoalveolar lavage (BAL), is a procedure in which sterile saline is introduced into a segment of the lung and then retrieved for cytological, microbiological, and molecular analysis. BAL is used to diagnose infections, inflammatory diseases, and certain malignant conditions affecting the alveolar and small-airway regions.

Overall, bronkoalveolaarinen describes processes and procedures that involve the bronchioles and alveoli, reflecting the functional and anatomical continuum of the lower respiratory tract.
