FIG 6. Angiograms of test animal 4.

A, Anteroposterior view IV DSA obtained 3 days after creation of aneurysm at origin of right CCA. Brachiocephalic arteries are opacified, including the left CCA (curved arrow), right subclavian artery (open arrow), and aneurysm cavity (straight solid arrows). The aneurysm cavity measures 4.0 mm in width.

B, Anteroposterior view IV DSA obtained 4 months after creation of aneurysm. The aneurysm cavity has markedly enlarged in size as compared with the earlier image, with the aneurysm cavity measuring 6.0 mm in width.
