Objective To investigate the prognosis of using the single stenting implantation technique in the treatment of very small aneurysms of the intracranial internal carotid artery (ICA) .Methods The clinical data in 14 cases of very small aneurysms(diameter <3 mm) of ICA from August 2003 to January 2012 were collected ,4 males and 10 females ,aged 35-72 years old .5 cases adopted the single stenting implantation technique for conducting the embolotherapy and 9 cases were treated by the stent-assisted spring coil embolization technique .Results Of 14 cases of aneurysms ,13 cases succeeded in endovascular embolization treatment and 1 case(7 .1% ) appeared aneurysms rup-turing hemorrhage .The complete occlusion rate of aneurysms and the complete symptomless rate after 9 months in the only stent implantation group were 80 .0% and 60 .0% respectively ,which after 12 months in the stent-assisted spring coil group were 88 .9% and 55 .5% .Statistical results showed that the mRS scores of modifical Rankin scale in the only stenting group were significantly higher than that of the stent-assisted spring coil group (t= 4 .21 ,P=0 .039) ,however the complete occlusion rate of aneurysms was lower (χ2 =5 .09 ,P=0 .011) .Conclusion Adopting the single stent implantation embolization for treating very small aneurysms has the low complete occlusion rate ,but the patient′s prognosis and the survival quality are good with less complications .%目的：探讨单一支架置入技术栓塞治疗微小颅内动脉颈内动脉段（ICA）动脉瘤的预后。方法收集2003年8月至2012年1月收治的微小ICA动脉瘤（直径小于3mm）患者14例的临床资料，其中男4例，女10例；年龄35～72岁。采用单一支架置入技术栓塞治疗5例，采用支架辅助弹簧圈栓塞技术治疗9例。结果13例血管内栓塞治疗微小ICA动脉瘤手术完全成功，1例（7．1％）患者出现术中动脉瘤破裂出血。仅支架置入组9个月后动脉瘤完全闭塞率80．0％，完全无症状率60．0％；支架辅助弹簧圈组12个月后完全闭塞率88．9％，完全无症状率55．5％。统计结果显示，仅支架置入组患者的改良Rankin量表（mRS）评分较支架辅助弹簧圈组高（t＝4．21，P＝0．039），但是其动脉瘤完全闭塞率较低（χ2＝5．09，P＝0．011）。结论采用单一支架置入栓塞微小动脉瘤的患者完全闭塞率较低，但是患者的并发症少、预后生存质量较高。
