Safety of bronchial arterial embolization with n-butyl cyanoacrylate in a swine model

Figure 3 Microscopic study. A: The bronchial branch artery with embolization of n-butyl cyanoacrylate lipiodol (NBCA-Lp) shows that the bubble-like space corresponds to NBCA-Lp (asterisks) containing red thrombus (arrowhead), with stripping of endothelial cells (arrow) and infiltration of the inflammatory cells (hematoxylin eosin stain × 100); B: The bronchial branch artery with embolization of gelatin sponge particles (GSP) shows amorphous substance corresponding to GSP (arrow) surrounded by red thrombus with infiltration of inflammatory cells (asterisks) (hematoxylin eosin stain × 100); C: The bronchial wall revealed the bronchial branch artery (arrows) embolized with NBCA-Lp outside the cartilage and the patency of numerous fine networks (asterisks) in the submucosal and cartilage layers (hematoxylin eosin stain × 100).
