Abstract:
Objective To assess the technical feasibility and efficacy of the combined application of a flexible,self-expanding neurovascular stent(Neuroform)and Gugliebni detachable coils(GDC)in the management of wide-necked intracranial aneurysms in humans.Methods Sixty-five wide-necked aneurysms which underwent 65 endovascular procedures were performed by using intracranial stent and GDC.There was a total of 30 aneurysms at basilar artery including 16 at the basilar tip,9 at the basilar trunk and 5 at the beginning of the basilar artery.And there were 30 aneurysms located at the posterior communicating artery, and 5 aneurysms located at the vertebral artery.The Neuroform stents were deployed to cover the neck of aneurysms.Another microcatheter was introduced into the aneurysm sac through the stent interstices and then detachable coils were released to embolize the aneurysms.Results The combined procedures were successful in all of the 65 patients with wide-necked aneurysms.The stent could pass smoothly through the intracranial artery and got released.Complete occlusion was achieved in 60 patients and incomplete occlusion in 5 patients.In-stent thrombosis occurred in 2 patients.All patients recovered well.Forty-two patients had followe-up angiography at 3 to 6 months after the procedure.Among them,no filling was found for the 39 aneurysms which were densely packed,and 3 aneurysms had neck remnant.Conclusion The implantation of Neuroform stent as a complimentary device to GDC coiling is easy and safe for embolization of wide-necked intracranial aneurysms.It has great advantage for treatment of wide-necked intracranial aneurysms.
