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

Abstract

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.
