Endovascular embolization for intracranial aneurysms: report of 88 cases

Objective To summarize the experiences of endovascular embolization for intracranial aneurysms, emphatically discuss the techniques, complications and the preventions. Methods Ninety aneurysms in 88 patients were treated by detachable coil embolization. Among them, 28 cases were treated by GDC, 18 by DCS, and 42 by EDC. Results Seventy aneurysms were 100% occluded, 13 were 90%~95% occluded, and 5 were 80% occluded. The complications associated- operation occurred in 9 patients. The coil escaping from the sac of aneurysm into its parent artery was seen in 3 patients. Four patients suffered form rerupture of aneurysm during the operation. Serious vasospasm was seen in 2 patients. Two patients died of complications. Conclusions The 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.
