Figure 5From: Corrosion casting of the subglottis following endotracheal tube intubation injury: a pilot study in Yorkshire pigletsGross and microscopic appearance of subglottic corrosion casts after hypoxic endotracheal tube cuff injury. (A) SEM image of subglottic lumenal surface showing an interconnected mesh of capillaries. Vessel buds, intussusceptions, resin extravasations, and vessel corrugations are seen (other angiogenic and hypoxic or degenerative features are not visible).Back to article page
