Comparison of Clinical Outcomes Using 10 Coil Versus 14 Coil in Endovascular Coil Embolization for Small and Medium-sized Intracranial Aneurysms: Efficacy of 14 Coil

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.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).Results: The mean volume embolization ratio was significantly higher (14 coil 37.5 ± 8.8%, 10 coil 32.6 ± 8.4%; P
