摘要目的 探讨颈内动脉床突上段血泡样动脉瘤(BBA)的手术技巧.方法 对7例开颅手术夹闭的BBA进行分析,采取额极软脑膜下分离,预先或术中临时阻断载瘤动脉,直接游离瘤颈两侧或载瘤动脉相连续部,分离出能够通过动脉瘤夹闭小空间即可,不必完全显露瘤体;强调选用小弯形动脉瘤夹一次夹闭,如果瘤颈撕裂在载瘤动脉临时孤立无充盈状态下,将瘤颈根部包括载瘤动脉壁连续部部分动脉壁一并夹闭.结果 本组6例术后完全康复;1例术后2周出现大脑半球大面积梗死,肢体偏瘫,痴呆.结论 采用特殊的手术技巧,能够减少BBA的手术风险,提高治愈率.

abstractsObjective To explore the surgical techniques for rare blood blister - like aneurysm (BBA) in the superior segment of clinoid process of internal carotid artery. Method The clinical data of seven cases of BBAs were studied. The separation of pia mater of the frontal pole was performed. The parent artery was blocked temporarily during the surgery. Sculpture type was adopted to directly dissociate the continuation part between the aneurysm neck and parent artery to get a small space enough for incarceration of aneurysm without exposure of the entire aneurysm. One incarceration of the lesser curvature - like aneurysm clip was specially performed to temporarily isolate the parent artery in the case of avulsion of aneurysm neck,to incarcerate the aneurysm root including the continuous part of parent artery wall in a nonfilling state. Results There were 6 cases of complete recovery after operation, 1 case of large area infarction of hemicerebrum after 2 weeks of operation resulting in hemiplegia and dementia Conclusions Special surgical techniques could reduce the surgical risk for BBA and improve curative rate.
