Atelectatic Bronchiectasis

Atelectatic Bronchiectasis in Childhood.

The occasional occurrence in radiograms of the chest of triangular shadows, situated behind the heart-shadow on the left or across the cardiophrenic angle on the right, has attracted the attention of radiologists for many years. It is, however, only since the introduction of lipiodol for diagnostic purposes that the frequent association of these shadows with bronchiectasis has been recognized. ...

Atelectatic or compensatory bronchiectasis.

Atelectasis or collapse of the lung as a cause of bronchiectasis is not by any means a recent idea. Reynaud, as long ago as 18351, in a comprehensive study of bronchial obstruction, noted that dilatation of the lumen might be present both proximal and distal to the obstruction. The dilatation proximal to the obstruction he ascribed to the increased force of the inspired air held up at the obstr...

Massive atelectatic bronchiectasis associated with bronchial stenosis.

Acute Massive Atelectatic Collapse of the Lungs

The following case appears to be worthy of record :? Mr. N., set. 56, was admitted into hospital on 24th January, 1933, complaining of fever with rigors for the last four days. About three weeks ago the patient had a sharp attack of influenza from which he had not wholly recovered when lie got the present attack of fever. He is subject to intermittent attacks of malaria. On admission his temper...

Stress concentration around an atelectatic region: a finite element model.

Lung parenchyma surrounding an atelectatic region is thought to be subjected to increased stress compared with the rest of the lung. Using 37 hexagonal cells made of linear springs, Mead et al. (1970) measured a stress concentration greater than 30% in the springs surrounding a stiffer central cell. We re-examine the problem using a 2D finite element model of 500 cells made of thin filaments wi...
