Histopathological study of vascular changes after intra‐arterial and intravenous injection of N‐butyl‐2‐cyanoacrylate

The histopathological changes after injection of N-butyl-2-cyanoacrylate were similar in the arteries and the veins with the exception of hyperplasia of elastic fibrils in the arterial wall and inflammation and necrosis in the venous wall at 2-3 weeks. Glue extrusion was seen in both arteries and veins.
