Endovascular embolization for intracranial aneurysms: Report of 162 cases

Abstract

Objective: To summarize the experiences of endovascular embolization for intracranial aneurysms and emphatically discuss techniques, complications and preventions. Methods: 171 aneurysms in 162 patients were treated by detachable coil embolization. Among them, 38 cases were treated by GDC, 35 by DCS, and 89 by EDC. Results: 137 aneurysms were 100% occluded, 27 were 90-95% occluded, and 7 were 80% occluded. Complications associated with operation occurred in nine patients. The coil escaping from the sac of aneurysm into its parent artery was seen in five patients. Six patients suffered from rupture of aneurysm during the operation. Serious vasospasm was seen in five patients. Two patients died of complications. Conclusions: Endovascular embolization is a safe, effective and minimally invasive method for treating intracranial aneurysms. Choosing exact embolization techniques is very important to improve the therapeutic effect and decrease the complications of embolization of intracranial aneurysms. © Springer-Verlag/Wien 2011.
