Stent-assisted coiling of cerebral aneurysms using the Enterprise and the Solitaire devices

Neurol Res. 2014 May;36(5):461-7. doi: 10.1179/1743132814Y.0000000356. Epub 2014 Mar 21.


Objective: To evaluate the technical feasibility, peri- and post-procedural morbidity and mortality as well as clinical and angiographic follow-up using the Enterprise and the Solitaire stent currently available to be used for stent-assisted coiling of broad-based cerebral aneurysms.

Material and methods: We conducted a retrospective study to investigate differences in aneurysms stented with the Enterprise (n = 58) and Solitaire stents (n = 19). Angiographic follow-up (mean: 8.25 onths) was available in 82.6% of patients treated with stent-assisted coiling.

Results: All stents were successfully deployed. There is a higher acute in-stent thrombosis complication in Solitaire stent placement (P = 0.012). However, we observed no significant differences in peri-procedural morbidity and mortality rate (P = 0.253), angiographic results (P = 0.411), recurrence rate (P = 1.000), or long-term neurological deficit (P = 0.435).

Conclusion: Both stents exhibited similar immediate and mid-term results with major neurological morbidities and mortality rate being low. More thrombogenic complications overall were found in Solitaire group.
