What does pulmonary emphysema mean?
Pulmonary emphysema is a chronic lung condition. It’s often part of COPD, a group of lung diseases that cause airflow blockage and breathing problems. It develops very slowly over time. It’s most often caused by smoking.
What is the pathophysiology emphysema?
Emphysema is a pathologic diagnosis defined by permanent enlargement of airspaces distal to the terminal bronchioles. This leads to a dramatic decline in the alveolar surface area available for gas exchange. Furthermore, loss of alveoli leads to airflow limitation by 2 mechanisms.
What is Panlobular?
Panlobular (or panacinar) emphysema is a type of emphysema that affects a specific part of the lungs. Emphysema is a disease of the lungs in which the air sacs in the lungs (alveoli) are permanently damaged.
What is emphysema scholarly article?
Emphysema is primarily a pathological diagnosis that affects the air spaces distal to the terminal bronchiole. It is characterized by abnormal permanent enlargement of lung air spaces with the destruction of their walls without any fibrosis and destruction of lung parenchyma with loss of elasticity.
What is pathophysiology for COPD?
Pathophysiology is the evolution of adverse functional changes associated with a disease. For people with COPD, this starts with damage to the airways and tiny air sacs in the lungs. Symptoms progress from a cough with mucus to difficulty breathing. The damage done by COPD can’t be undone.
What is the difference between Panlobular and centrilobular emphysema?
Centrilobular emphysema appeared to be mainly a disease of the upper lobe and the apices within the upper and lower lobes. In contrast, panlobular emphysema was a more or less diffuse process within lobes and lungs with mild preferential involvement of the lower lobe.
What is the difference between Centriacinar and Panacinar emphysema?
Panacinar emphysema seems to be more severe in the lower lobes, whereas centriacinar emphysema usually predominates in the upper lobes. Panacinar emphysema is associated with alpha1-antitrypsin deficiency but can also be found in patients in whom no genetic abnormality has been identified.
