Description

The authors report initial clinical experience of new detachable coils in the treatment of cerebral aneurysms. Micrusphere coils and Microplex complex coils were introduced in Japan in 2006. These coils have a unique three-dimensional shape, suitable for framing the aneurysm. We mainly used these coils for the purpose of initial frame formation in the aneurysmal dome and evaluated their characteristics in this study. Over the last 8 months, 58 patients with intra-cranial aneurysm were treated using detachable coils at our institution. Of them, 14 patients were treated using Micrusphere, and 11 using Microplex. The Micrusphere coil was suitable for initial frame formation into a global shape with a relatively broad neck. The Microplex coil was able to produce a nice basket even in multi-lobulated or spindly aneurysms. It is imperative that all operators have precise understanding of the new coils prior to clinical use.
