dc.description.abstractBackground: Self-expandable stents have been increasingly used for endovascular treatment of intracranial aneurysms. Because the usage of intracranial stents has increased overall, total numbers of complications associated with these devices have increased. Thrombosis, distortion, or incomplete opening of stents are potential complications that may result in occlusion of the parent artery. In such cases, removal of the stent (stentectomy) may be the only solution to avoid serious clinical consequences. Objective: To investigate the feasibility and efficacy of a novel stentectomy technique for removal of thrombosed self-expandable stents. Methods: A retrospective review was performed of patients who underwent the stentectomy procedure. Initial and follow-up imaging and clinical outcomes were assessed. Immediate postprocedural and follow-up clinical statuses were assessed using the modified Rankin scale. Results: Seven patients were included in this study (mean age: 54.1 years). The stentectomy was successful in 6 of 7 patients (85.7%). Seven stents in 6 patients were successfully removed to treat the acute in-stent thrombosis that was resistant to alternative bail-out treatments. The removed stents were self-expandable braided in 2 patients, flow diverters in 2 patients, and laser cut open-cell stents in 2 patients. Stentectomy failed to retrieve a thrombosed braided stent in 1 patient. The modified Rankin scale score of all patients who underwent a success stentectomy was <= 1. Conclusion: The stentectomy procedure using the defined technique is feasible to retrieve thrombosed stents and effective to restore the blood flow. It can be considered a last resort option to treat acute in-stent thrombosis resistant to alternative bail-out treatments.
