Fig 3.

Postoperative angiograms showed total occlusion of the aneurysm sac, with no residual contrast material filling of the aneurysm sac or neck.

A, Magnified postoperative anteroposterior angiogram shows the densely packed aneurysm sac (straight arrow). No coils extend into the well-visualized aneurysm neck (curved arrow).

B, Subtracted postoperative anteroposterior angiogram shows no residual blood flow in the aneurysm sac (solid arrow). Cross filling of the anterior cerebral artery (curved arrow) can be seen.
