Balloon-expandable stenting with and without coiling for wide-neck and complex aneurysms

Background: Wide-necked, saccular, dissecting, and fusiform intracranial aneurysms are poor coil retainers. Retention can be improved by parent-artery stenting across the aneurysm. Methods: We used a balloon-expandable stent and delivery system, intending to treat 38 aneurysms in 36 patients. Stents could not be advanced across the neck of 2 aneurysms near the ophthalmic artery origin. These cases were managed by temporary balloon remodeling and coiling. Stenting alone was done for 15 aneurysms, including 7 in vertebral artery V4 segments. Stenting with immediate or delayed coiling was done in 21 aneurysms. Resu…
