<p>Objective: The purpose of this retrospective study was to compare the therapeutic results of middle-sized or small cerebral aneurysms coiling using 10 coil (thickness, 0.0095 inch–0.012 inch) and 14 coil (thickness, 0.0135 inch) as a complex framing coil.</p><p>Methods: Fifty aneurysms (maximum size, 4 mm–10 mm) in 50 patients treated in our hospital between May 2012 and May 2015 were assigned in this study. We compared the volume embolization rate, recurrence rate, initial occlusion grade between 14 coil (25 aneurysms) and 10 coil (25 aneurysms).</p><p>Results: The mean volume embolization ratio was significantly higher (14 coil 37.5 ± 8.8%, 10 coil 32.6 ± 8.4%; P <0.05) in aneurysms coiled with 14 inch coil than those coiled with 10 inch coil. Fourteen inch coil has a higher initial occlusion grade, and lower recurrence rate than 10 coil, but these differences were not significant.</p><p>Conclusion: The use of 14 inch framing coil to embolize middle-sized or small cerebral aneurysms is more effective in terms of a higher packing ratio.</p>
