Objectives: To assess the pathological differences between PSE and CLE in chronic obstructive pulmonary disease (COPD).

A A B B 2019-06-06 Paraseptal emphysema can be one of the many causes of spontaneous pneumothorax. Although the exact pathogenesis is unclear, the relationship between paraseptal emphysema and thin and tall body habitus has led to the suggestion that this subtype of emphysema is due to the effects of gravitational pull on the lungs, with a greater negative pleural pressure at the lung apices. paraseptal emphysema (PSE) vs diffuse centrilobular emphysema (CLE), and (4) upper vs lower vs diffuse CLE. Materials and Methods Subjects COPDGene10 is a longitudinal multicenter prospective cohort study focused on the genetic and epidemiological characteristics of COPD. Global paraseptal emphysema was scored independently of CLE and PLE as follows: none, mild, moderate, severe. Study Participants. This paper focuses on smokers with COPD and without alpha-1 antitrypsin deficiency, who had emphysema extent greater than 4.8% measured by QCT. Emphysema is classified as centrilobular (subclassified as trace, mild, moderate, confluent, and advanced destructive emphysema), panlobular, and paraseptal (subclassified as mild or substantial).
