The stent-assisted coil embolization technique has been increasingly used in the clinic, but its efficacy and safety have yet to be assessed. This study aimed to evaluate the efficacy and safety of stent-assisted coiling in the treatment of micro-intracranial wide-necked aneurysms. Between May 2007 and November 2011, a total of 35 micro-intracranial wide-necked ruptured aneurysms were occluded with Enterprise stent-assisted coils. The patients were followed up for two years. Stent-assisted coiling was performed successfully in all cases, and stent placement was satisfactory without any complications. Of 35 aneurysms, 13 (37.1%) were completely occluded, ten (28.5%) had residual necks, and 12 (34.2%) had residual aneurysms. In the two-year follow-up, no aneurysm rupture occurred and no patients had nerve dysfunction. All patients were reviewed by digital subtraction angiography or computed tomography angiography. One patient had a residual neck (2.8%), and no patients experienced stent restenosis or thromboembolic events. In general, stent-assisted coiling is effective and safe for the treatment of micro-intracranial wide-necked aneurysms.
