Abstract: Objective To summarize the technique of stent combined with coils to treat middle cerebral artery bifurcation wide-necked aneurysms. Methods 15 patients were reported. Results 11 of 15 aneurysms were completely occluded and 4 were incompletely (>95%) occluded. Transient ischemia of cerebral occurred in a case. 8 aneurysms were followed up for 6～12 months, 1 presented neck remnant growth. Conclusion It is satisfied to use the stent combined with coils to treat middle cerebral artery bifurcation wide-necked aneurysm, which may protect the parent artery.
