1 Complications of Valve Lung Volume Reduction in a Case of Previous Pleurodesis 
Angela Koutsokera, MD, PhD, Leslie Noirez, MD, Michel Gonzalez, MD, Catherine Beigelman-Aubry, MD, Hans-Beat Ris, MD, John- David Aubert, MD, Alban Lovis, MD  The Annals of Thoracic Surgery  Volume 98, Issue 3, Pages e71-e72 (September 2014) DOI: /j.athoracsur Copyright © 2014 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Computed tomographic (CT) scan of the chest, before endobronchial valve placement. (A) Frontal view of the chest CT scan showing extensive emphysema; (B) three-dimensional quantitative assessment of emphysema with the density mask technique. The latter is defined as the percentage of the total lung volume that contains voxels with attenuation values below a threshold of −950 Hounsfield Units.

3 Fig 2 (A) Computed tomographic scan of the chest after endobronchial valve placement, showing the valve-induced LUL (arrow) atelectasis, the pneumothorax, and the residual pleural cavity (arrow). (LLL = left lower lobe; LUL = left upper lobe.) (B) After endobronchial valve removal, showing the reexpansion of the LUL, which was coincident with the cessation of the air-leak.
