A 56-year-old woman was admitted to stent-assisted coiling for a 2-mm A1 aneurysm of the left anterior cerebral artery and a left 3-mm internal carotid artery aneurysm. While coiling the A1 aneurysm, the first 2 mm × 20 mm coil migrated through the 4.5 mm × 37 mm Enterprise stent struts, lodging at the distal anterior cerebral artery. A 4 mm × 15 mm Solitaire AB stent was used successfully in this case to remove the displaced coil. The A1 aneurysm was re-treated with a 2 mm × 40 mm coil after placement of the Enterprise stent, and the ophthalmic ICA aneurysm was also coiled through the stent struts. The patient was neurologically intact after treatment.
