目的　探讨可脱性球囊在颅内动脉瘤介入治疗中的价值及缺点 ,并探讨不同大小动脉瘤的栓塞技巧。方法　 2 0例动脉瘤患者中 ,小动脉瘤 8例 (〈12mm〉 ,大动脉瘤 7例 (12～ 2 5mm) ,巨大动脉瘤 5例 (>2 5mm)。 14例患者行动脉瘤腔内直接栓塞治疗 ,6例行载瘤动脉闭塞。结果　 14个采用球囊行瘤腔内栓塞的动脉瘤中 ,3个月后DSA随访 ,10个动脉瘤被完全栓塞 ,4个动脉瘤部分栓塞。 6例采用球囊行载瘤动脉闭塞的动脉瘤患者 ,3个月DSA随访皆未见动脉瘤显影。结论　颅内大动脉瘤或巨大动脉瘤的可脱性球囊瘤腔内直接栓塞治疗是一种行之有效的治疗方法 ,外科不能手术或行瘤腔内直接栓塞治疗难度较大的某些动脉瘤 ,载瘤动脉的闭塞治疗仍不失为一种有效的治疗方法 Objective To investigate the value and shortcomings of detachable balloon in the interventional treatment of intracranial aneurysms and explore the embolization skills of aneurysms of different sizes. Methods Twenty patients with aneurysm included 8 aneurysms (<12 mm>, 7 aneurysms (12-2 mm) and 5 giant aneurysms (> 2 5 mm. Embolization and embolization in 6 cases.Results Of the 14 aneurysms with balloon embolization in the aneurysm, DSA was followed up 3 months later, 10 aneurysms were completely embolized and 4 aneurysms were partially embolized.6 In patients with aneurysm with balloon-occluded aneurysm, no aneurysm developed at 3-month follow-up in DSA.Conclusion The intracapsular direct embolization of intracranial aortic aneurysm or giant aneurysm is a Effective treatment methods, surgery can not surgery or intracavitary direct embolization of the treatment of some aneurysms more difficult, occlusion of the parent artery is still an effective treatment
