Analyze The Clinical Efficacy And Safety Of Embolization The Internal Carotid Artery Aneurysm With Wide Neck Assisted By The New Retrievable Self Expanding Stent(LEO)

Objective:To study the clinical efficacy, safety and prognosis of novel LEO stent-assisted embolization for internal carotid artery wide-necked aneurysms.Methods:Total 89 intracranial aneurysm cases were retrospectively reviewed.47 cases with internal carotid artery wide-necked aneurysms were treated with LEO stent-assisted embolization, while the rest 42 cases with regular-necked aneurysms treated with mere coil embolization were studied as control.3D-DSA was performed immediately after embolization and image study (MRA or DSA) was repeated in the follow-up after 3-6 months. Lon-term complication and functional outcome (GOS) was evaluated in the period of 6-12 months after surgery.Results:Compared with control group, LEO stent-assisted embolization group showed no significant differences in the efficacy, complication and GOS (P> 0.05).Conclusion:The novel LEO stent-assisted embolization is efficacious in treatment of internal carotid artery wide-necked aneurysms, with low risk of complications and good outcome.
