Embolization therapy for the anterior circulation aneurysms

Objective To study the effect of embolization therapy for the anterior circulation aneurysms. Methods Forty-five Hunt and Hess I-IV patients with the anterior circulation aneurysms were treated by variant endovascular methods,including simple coil embolization、ballon-assisted coil embolization technique,stent-assisted coil embolization technique. Results 35 patients were treated by simple coil embolization;7 patients were treated by ballon-assisted coil embolization technique; 3 patients were treated by stent-assisted coil embolization technique. Among patients,37 cases were completely occluded; 8 cases were subtotally occluded. No coil escaping from the aneurysms neck or other complications occurred; 25 patients were discharged with a GOS score of 5; 15 with a score of 4; and 5 had a score of 3. In the follow-up for 3 ~ 24 months after the embolization,recurrence was not found. Conclusion Embolization therapy for the anterior circulation aneurysms is reliable and safe,which can effectively reduce the disability and mortality of patients with aneurysm.
