Radiologic manifestations of bronchoscopic lung volume reduction in severe chronic obstructive pulmonary disease

Abstract

OBJECTIVE. Bronchoscopic lung volume reduction promises to become an effective treatment option in severe chronic obstructive pulmonary disease. Several techniques are currently being investigated, including implantation of devices into the lung and instillation of hot water vapor or polymer. This article reviews the spectrum of radiologic manifestations on chest radiography and CT that occur after the intervention. CONCLUSION. Familiarity with the intended effects and adverse events will aid the radiologist in supporting bronchoscopic lung volume reduction.

Keywords: bronchoscopic lung volume reduction; chronic obstructive pulmonary disease (COPD); diaphragm; emphysema.
