From: Case report of severe bronchial web-like stenoses after ‘surviving the unsurvivable’
Bronchoscopic images after deterioration with severe type II respiratory failure requiring intubation and mechanical ventilation. Image a demonstrates total membranous occlusion of Rb1b and image b demonstrates this airway after opening via puncture of the membranous stenosis by Wang needle then balloon dilatation. Image c reveals near complete stenosis of the left upper lobe superior division bronchus. Image d demonstrates the view beyond this stenosis after dilatation, revealing a normal variant Lb1 / Lb2 / Lb3 configuration of the left upper lobe segmental bronchi
