| Abstract: | Objective: This was a retrospective review of the results using stent‐assisted coil embolization for management of intracranial aneurysms. Methods: The records of seven patients treated with stent‐assisted Gugliemi detachable coil (GDC) embolization were retrieved from the authors’ prospectively maintained database. The clinical presentation, site and type of aneurysms, treatment procedure and complications, and outcome of these identified cases were reviewed. Results: Between January 2002 and May 2004, seven patients with intracranial aneurysms, four of which were ruptured, were treated by stent‐assisted GDC embolization. Four aneurysms were located at the anterior circulation and three were at the posterior circulation. The indications for stent use were: giant aneurysm (>2.5 cm), dissecting pseudo‐aneurysm, broad‐necked aneurysm and the need for preservation of important parent arteries or branches. Concerning the technical aspect, all except one had successful stent deployment. One stent dislodged after apparent successful deployment. GDC embolization was continued and the aneurysm was partially occluded. More than 90% occlusion of aneurysm sac was achieved in six aneurysms. Intraoperative complications included over‐coagulation, failure in stent deployment, displacement of stent, coil entrapment and thromboembolism. One patient had added focal neurological deficit after the procedure, and one became vegetative due to an unrelated cause. The patient in whom the stent was dislodged suffered another subarachnoid haemorrhage 4 months later and died. Conclusion: Percutaneous intracranial stent is a new and useful device to assist embolization of cerebral aneurysms that were previously not amenable to endovascular therapy. These preliminary results suggest that this procedure could achieve satisfactory outcomes without significant complications. |
