Clinical Analysis of Endovascular Embolization of Intracranial Aneurysms

Objective To summarize the technique of endovascular embolization of intracranial aneurysms and its curative effect. Method The endovascular embolization was performed in 76 patients with 80 intracranial aneurysms. Of 23 wide neck aneurysms, 4 were treated by balloon-assisted remodeling of aneurysmal neck technique, 5 by microwire-assisted coiling technique and 14 by stenting combined with coils embolization. Of 6 giant aneurysms, 5 were treated by occluding parent arteries with detachable balloon, and 1 with Guglielmi detachable coils. Results Total occlusion of 48 aneurysms (64.9%, 48/74), more than 90% occlusion of 11 aneurysms (14.9%, 11/74), less than 90% occlusion of 15 aneurysms (20.3%, 15/74) were reached. Bleeding caused by aneurysm rupture occurred in 4 cases (5.3%, 4/76). Two patients died of aneurysm rupture. Conclusions It is suggested that embolization of intracranial aneurysms with detachable coils is minimally invasive, safe, effective and reliable. The techniques such as microwire-assisted coiling, remodeling of aneurysmal neck and stenting can enhance the total occlusion rate and decrease cerebral infarction rate in the patients with intracranial aneurysms.
