Pulmonary emphysema: when more is less.

David G . Morris and Dean Sheppard Pulmonary Emphysema : When More is Less

Pulmonary emphysema, cardio-respiratory disturbance.

Pulmonary emphysema, as the term is generally used clinically, refers to an overinfiation or distention of the lungs (localized or diffuse), characterized by a relative increase in the amount of air which cannot be blown out with a forced expiration. The residual air capacity plus the vital capacity equals total observed lung capacity (TLC) for the individual, and in pulmonary emphysema the TLC...

Functional results of surgery for bullous emphysema.

Forty-six patients with bullous emphysema were operated on. Respiratory function was investigated before and immediately after surgery, and during the follow-up to five years. The larger the volume of the bullae, the less disturbances of lung function caused by their removal immediately after operation. Respiratory function improved significantly during the long-term follow-up after removal of ...

Quantitative computed tomography measurements of emphysema for diagnosing asthma-chronic obstructive pulmonary disease overlap syndrome

BACKGROUND The diagnostic criteria of asthma-COPD overlap syndrome (ACOS) are controversial. Emphysema is characteristic of COPD and usually does not exist in typical asthma patients. Emphysema in patients with asthma suggests the coexistence of COPD. Quantitative computed tomography (CT) allows repeated evaluation of emphysema noninvasively. We investigated the value of quantitative CT measure...

Smoking-related interstitial fibrosis combined with pulmonary emphysema: computed tomography-pathologic correlative study using lobectomy specimens

PURPOSE To evaluate the incidence and pathologic correlation of thin-section computed tomography (TSCT) findings in smoking-related interstitial fibrosis (SRIF) with pulmonary emphysema. PATIENTS AND METHODS Our study included 172 consecutive patients who underwent TSCT and subsequent lobectomy. TSCT findings including clustered cysts with visible walls (CCVW) and ground-glass attenuation wit...
