Treatment of intracranial bifurcation aneurysms with “X” stent-assisted coiling: A case series and literature review

      Highlights

      • In selected cases, “X” stent-assisted coiling is safe and effective for intracranial bifurcation aneurysms.

      Abstract

      Purpose

      To clarify the safety and efficacy of “X” stent-assisted coiling (X-stenting) for the treatment of intracranial bifurcation aneurysms and to review the literature.

      Methods

      We retrospectively reported five consecutive patients with six intracranial bifurcation aneurysms who underwent X-stenting between June 2014 and June 2020. The clinical and angiographic results were analyzed. We also performed an extensive PubMed review of medical literature up to June 2021.

      Results

      Endovascular procedures were successfully applied to all six aneurysms. No procedure-related complications were noted. Follow-up angiograms were available for all patients and revealed occlusion in five aneurysms and improvement in one aneurysm. Clinical follow-up was performed for all patients, and the mRS score at follow-up was 0 in all patients. Thus, good outcomes were achieved in all patients, and no ischemic or hemorrhagic events were observed.

      Conclusions

      X-stenting appears to be safe for treating intracranial bifurcation aneurysms and effective in immediate and short-term outcome. Further research is required with well-designed, prospective studies with large sample sizes.
