Abstract:
Objective To compare the effectiveness and safety of different intracranial stents assisted coil embolization of intracranial aneurysms and to discuss the selection of different stent assisted embolization of intracranial aneurysm.Methods From 2007 April to 2012 April,118 cases (a total of 128 wide-neck aneurysms) with intracranial aneurysms were analyzed retrospectively.This included the use of 70 neuroform,38 Enterprise,and 20 Solitaire AB stents forthe treatment of intracranial aneurysms.The successful use,aneurysm occlusion at the immediate post-operation,and early period of peri-operative complications were recorded from those clinical data in order to assess the effectiveness and safety of the different intracranial stents,which assisted coil embolization of intracranial aneurysms.Rank sum test and x2 test were used for statistics.Results Three aneurysms assisted with Neuroform stent were planted unsuccessfully,and the Enterprise and Solitaire stents were placed successfully.The embolism results of three stents after immediate postoperative angiography aneurysm: Neuroform stent occlusion rate was 40.0％ (28/ 70),the tumor residual rate was 38.6 ％ (27/70),and the partial embolization rate was 21.4 ％ (15/70) ; The Enterprise stent occlusion rate was 42.1％ (16/38),the tumor residual rate was 36.8 ％ (14/38),and the partial embolization rate was 21.1％ (8/38).The Solitaire AB stent occlusion rate was 40.0 ％ (8/20),the tumor residual rate was 35.0 ％ (7/20),and the partial embolization rate was 25.0 ％ (5/20).There were not significant differences in aneurismal occlusion (H =0.12,P ＞ 0.05).Early peri-operative complications results were: Neuroform stent occurred in 7,Enterprise frame in 4,and Solitaire AB stent occurred in 2.There were no significant differences in the incidence of complications in the early period after coiling (x2 =0,P ＞ 0.05).Conclusions Three kinds of intracranial stents assisted embolization of intracranial aneurysms are applied safely and effectively.The stent may be chosen according to morphology of parent artery and stent biological character.
