The pathological changes in chronic bronchitis and emphysema.

Correlation of certain bronchographic abnormalities seen in chronic bronchitis with the pathological changes.

In their description of the changes seen in the bronchograms of patients with chronic bronchitis, Simon and Galbraith (1953) described the absence of peripheral filling as the most frequent change in the lung periphery and also the presence of " pools," the name applied to dense blobs of contrast medium, 3-5 mm. in diameter, which arise from the peripheral part of the bronchial tree. The presen...

The Pathological Changes in Chronic Bronchitis and Emphysema

Chronic bronchitis defies close definition, just as it has defied all attempts at prevention or cure. Its beginning is innocuous enough, being characterized by cough and clear mucoid sputum; yet this may lead to incapacitating breathlessness, heart failure and death. Pathologically the disease is disappointing in that there is no specific or diagnostic lesion, since in its early or mild stage t...

Lung Compliance and Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease, namely, pulmonary emphysema and chronic bronchitis, is a chronic inflammatory response of the airways to noxious particles or gases, with resulting pathological and pathophysiological changes in the lung. The main pathophysiological aspects of the disease are airflow obstruction and hyperinflation. The mechanical properties of the respiratory system and it...

Chronic bronchitis: radiological aspects of a five-year follow-up.

an active lesion nor a lesion related in any way to the chronic bronchitis or the clinical course. The second group, consisting of 35 or 12% of all the patients, were those in whom the radiograph showed evidence of local emphysema. This was diagnosed when a single and localized avascular translucent area was seen, which was either clearly demarcated by a hair-line shadow, suggesting a bulla, or...
