FIG. 1.

Cerebral angiograms demonstrating a migrated coil occlusion at the distal M1 segment of the right MCA (arrowhead). There was no contrast flow beyond the point of occlusion or contrast leakage into the subarachnoid space in the vicinity. The migrated coil was deemed irretrievable. It was noted that most of the coil material still occupied the giant aneurysmal dome volume (double arrowheads).
