Pneumothorax Complicating Pulmonary Emphysema

Ronald B. George, MD; Stephen J. Herbert, MD; Jay M. Shames, MD; Dean B. Ellithorpe, MD; Hans Weill, MD; Morton M. Ziskind, MD

JAMA. 1975;234(4):389-393.


Abstract

Clinical and roentgenographic findings were compared in patients 40 years of age and over and in those under 40 who were treated for acute unilateral pneumothorax. Dyspnea and anxiety were prominent in the older individuals, although pneumothoraces were usually small. Because physical findings were often unreliable, roentgenograms were required. In the presence of pulmonary emphysema, loss of retractility prevented total collapse of the underlying lung. Increased intrapleural pressure caused overexpansion of the chest wall and depression of the diaphragm without much mediastinal shifting. Partial collapse of emphysematous lobes demonstrated bullae that were not previously obvious. Respiratory failure developed in five patients over 40 years of age, but four of them recovered after relief of the pneumothorax. Mortality for the group was low and related to associated pulmonary diseases.
