EXPERIMENTAL PULMONARY COLLAPSE

Experimental massive pulmonary collapse.

Interest in atelectasis has in recent years been revived by the increased recognition of its frequency. It has been demonstrated that complete obstruction of the air passage supplying a unit of the lung which does not also communicate with another air passage will produce atelectasis.'3 It has been shown4 that this is due to absorption by the body fluids of the gases contained in that part of t...

Unilateral pulmonary collapse in asthmatics.

Five asthmatic patients developed collapse of one lung. Three of the patients were children and three of the five had repeated episodes of atelectasis. Episodes of atelectasis were usually associated with localised chest pain, which was not pleuritic in character, and with breathlessness, but without wheezing. The were not related to clinically apparent respiratory infections or to deterioratio...

Collapse Therapy of Pulmonary Tuberculosis

Massive pulmonary collapse during thoracotomy.

A 28-year-old housewife was admitted to hospital in congestive cardiac failure but treatment with digitalis resulted in rapid improvement. She had a past history of attacks of winter bronchitis and rheumatic fever at 12 years of age. Clinical examination suggested that the underlying lesion was stenosis of the mitral valve, and one month later the patient was referred to a thoracic surgeon for ...

Echocardiographic Observation of Juxtacardiac Pulmonary Collapse

Despite its value in the diagnosis of pericardial disease, two-dimensional echocardiography also is known to produce confounding results. Ten patients had juxtacardiac masses simulating pericardial tumor implants on echocardiographic examination(”pericardial pseudotumor”) caused by juxtacardiac pulmonary atelectasis or lobar collapse. The atelectatic nature of these masses was based on echocard...
