Highlights
- •The meta-analysis is to compare intracranial aneurysms treated with SAC and BAC.
- •Complete occlusion rate at the end of the procedure is similar between SAC and BAC.
- •Complete occlusion rate is higher with SAC at 6 months or later after the procedure.
- •Overall complication rates and retreatment rates are similar between SAC and BAC.
Abstract
Background
Stent-assisted coiling and balloon-assisted coiling are well-established minimally
invasive techniques for treatment of intracranial aneurysms. The aim of this study
was to use meta-analysis methods to compare clinical outcomes of aneurysms treated
with stent-assisted coiling versus balloon-assisted coiling.
Methods
We searched for two-arm prospective studies and retrospective studies that compared
the clinical outcomes in patients that received stent-assisted or balloon-assisted
aneurysm treatment. Database search was performed through May 2015. Odds ratios (OR)
with 95% confidence intervals (CI) were used to compare the clinical outcomes in patients
that underwent either stent-assisted or balloon-assisted coiling for intracranial
aneurysms management.
Results
Complete occlusion rates at the end of the coiling procedure were similar between
patients that received stent-assisted and balloon-assisted aneurysm treatment (OR = 0.763, 95% CI = 0.47 to 1.23, P = 0.270). However, complete occlusion rates were higher with stent-assisted coiling
at 6 months or later after the procedure (OR = 1.82, 95% CI = 1.21 to 2.74). The overall complication rates and retreatment rates in patients with
recurrence were similar between stent-assisted and balloon-assisted aneurysm treatments.
Conclusion
Stent-assisted coiling achieved better complete occlusion rates of aneurysms at 6 months or later after the procedure compared to balloon-assisted coiling, without
being associated with a higher risk of intraprocedural complications and retreatment.
