Fig 1. A, Angiogram of experimental aneurysm created on the common carotid artery of swine pre-embolization shows contrast filling of the aneurysm dome.

B, Postembolization angiogram of aneurysm with platinum coils. Aneurysm is tightly packed with platinum coils.

C, Angiogram of 12-week follow-up shows complete occlusion of aneurysm from the parent artery, suggesting the formation of a neointimal layer.
