Abstract:

ObjectiveTo discuss the curative effects of treating wide-necked intracranial aneurysms with different methods. MethodsWe retrospective analyzed 146 patients with a total of 152 wide-necked intracranial aneurysms which underwent surgical clipping and endovascular treatment from May 2008 to July 2011.The postoperative effectiveness was compared. The modified Rankin Scale(mRS) was used to evaluate the outcome. The mRS score =0-2 was defined as good outcome and the mRS score =3-6 score was defined as poor outcome. Results90 patients with 94 aneurysms were treated with surgical clipping.The followingup results of 3 to 24 mohths(mean 12.5 months)showed that there was no recurrence in all aneurysms. 92 aneurysms were clipped completely and 2 were clipped incompletely.The latter were clipped again.79 patients (87.8%) had good outcome. 56 patients with 58 aneurysms underwent endovascular treatment. The following-up results of 6 to 96 months(mean 36.2 months)showed that 8 recurrence aneurysms(13.8%). 50 patients (89.2%) had good outcome. The outcome of the two groups did not differ significantly(P>0.05). ConclusionBoth surgical clipping and endovascular treatment can treat wide-necked intracranial aneurysms effectively. Lower recurrence was associated with surgical clipping，but higher recurrence was associated with endovascular treatment in wide-necked intracranial aneurysms.
