case_images: CT-scan on day 16 showed a complete, left-sided pneumothorax (Figure 1). Central venous catheter placement on the left (internal jugular vein) was performed six days before the onset of the air leak.
case_images: CT-scan (left image) and chest X-ray (right image) after endobronchial valve placement. The left lung is again fully expanded. The circled areas depict the two endobronchial valves within the left upper lobe segmental bronchi (LB1/2 and LB3). The Avalon Elite  Bi-Caval Dual Lumen Catheter is visible on the chest X-ray (white arrow).

case_images: This initially led to an immediate decrease of the air leak to about 400-700 ml/min, and the left lung was then again fully expanded (Figure 2).
