Treatment For Cerebral Aneurysms

Re-rupture of cerebral aneurysms often occurs at their blebs, and the treatment of cerebral aneurysms harboring blebs has been considered difficult. To prevent rupture during embolization, the authors have tried to deliver coils only into aneurysm domes, without inserting coils, a microcatheter, or a microguidewire into the blebs. Here, to prove such a treatment strategy, the authors report early experience in 3 cases with cerebral aneurysms harboring blebs.

Coil embolization is the most common endovascular treatment for cerebral aneurysms at many centers [1]. Nevertheless, the coiling of wide-neck aneurysms is a challenge. Incomplete filling of the aneurysmal sac due to coil configuration challenges and aneurysmal growth can often lead to recurrence. To assist treatment with coils, clinicians may deploy a high porosity stent in a staged process to act as a supporting bridge for coils. The stent is first deployed across the aneurysmal neck, and multiple coils are then deployed into the aneurysmal sac 6–8 weeks later [2]. Under certain circumstances, coil deployment is not possible and high porosity stents alone are used for treatment [2–3].

Novel Device

Object The authors describe a novel device for the endovascular treatment of intracranial aneurysms, the endovascular clip system (eCLIPs). Descriptions of the device and its delivery system as well as the results of flow model tests and the treatment of experimental aneurysms are provided. Methods The eCLIPs comprises a flexible hybrid implantable device (an anchor and a covered leaf) and a balloon catheter delivery system, designed to be positioned and activated in the parent vessel in such a way that the covered portion will abut the aneurysm neck. The eCLIPs was subjected to testing in glass, elastomeric, and cadaveric flow models to determine its navigability, orientation, and activation compared with commercially available stents. In a second experiment, 8 carotid artery sidewall aneurysms in swine were treated using eCLIPs. The degree of occlusion was observed on angiography immediately following and 30 days after device activation, and a histological analysis was performed at 30 days. Results The device could navigate tortuous glass models and human cadaveric vessels. Compared with commercially available stents, the eCLIPs performed well. It could be navigated, oriented, and activated easily and reliably. With regard to the 8 porcine experimental aneurysms, immediate postactivation angiograms confirmed complete occlusion of 4 lesions and near occlusion of the other 4. Angiographic follow-up at 30 days postactivation showed occlusion of all 8 aneurysms and patency of all parent vessels. Histopathological analysis revealed aneurysm healing, with smooth-muscle cells growing across the lesion neck to allow reendothelialization. Conclusions Aneurysm occlusion with a single extrasaccular endovascular device has potential advantages. The authors believe that eCLIPs may prove to be a useful tool in the endovascular treatment of cerebral aneurysms. The system should reduce risks associated with coiling, procedure time, costs, and radiation exposure. The device satisfactorily occluded 8 experimental sidewall aneurysms. The observed healing pattern is similar to that seen after microsurgical clipping.

Initial Clinical Experience

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.
