We aimed to verify that Micrus 3D microcoils can be used as first coils in the treatment of saccular wide-necked aneurysms to provide stable protection to the neck by keeping the coil mesh inside the aneurysm. We selected 22 wide-necked aneurysms and calculated the ratio between sac diameter and neck width which was close to unity. The aneurysms were treated by endovascular approach using Micrus 3D (Spherical) microcoils as first coils. The coils proved stable during placement and detachment and compatible with both GDC and Micrus coils used for filling and packing. The endovascular procedure was suspended in only two out of 22 aneurysms selected for treatment. Aneurysm bleeding occurred in two endovascular procedures but was controlled. No complications were encountered in the remaining 18 patients treated. The percentage of technical failures has been reduced since the adoption of 3D Micrus microcoils in our practice.
