We present our initial clinical experience of Dendron Variable Detachable System (VDS) coils, now Sapphire VDS from MTI, in the endovascular treatment of cerebral aneurysms. VDS coils, uniquely, can be detached at variable points along their length, allowing placement of as much or as little as desired of the coil within the aneurysm. Our ten patients formed part of a multicentre feasibility study. VDS coils were successfully deployed in all but one aneurysm. The electrolytic detachment mechanism with practice is both simple to use and reliable. The coils are however slightly stiffer than standard coils limiting their use in small aneurysms. This remains a technology in evolution.
我们展示了Dendron可变可分离系统（VDS）线圈（现MTI公司的蓝宝石VDS）用于脑动脉瘤血管内治疗的初步临床经验。独特的是，VDS线圈可在其长度方向的不同点分离，从而能够根据需要在动脉瘤内放置或多或少的线圈。我们的10名患者是一项多中心可行性研究的一部分。除1个动脉瘤外，VDS线圈在其他所有动脉瘤中均成功植入。经过实践，电解分离机制使用简单且可靠。然而，这些线圈比标准线圈稍硬，限制了它们在小动脉瘤中的应用。这仍是一项不断发展的技术。
