摘要： 探讨基底动脉顶分叉部动脉瘤的手术适应证及手术操作技巧。回顾分析3 例经颞下入路手术治疗基底动脉顶分叉部动脉瘤患者临床表现、影像学资料及手术过程。其中2 例动脉瘤完全夹闭，1 例因保护穿支动脉而残留部分瘤颈。术后随访6 个月至2 年，均恢复良好，改良Rankin 量表评分分别为2分、0分、1分；日常生活活动能力量表（Barthel指数）评分为65分、100分和95分。

Abstract: The study was to explore the operative experience in 3 patients with basilar bifurcation aneurysms treated with microsurgery via subtemporal approach. The clinical manifestations, angiograms, and surgical operation were retrospectively analyzed. The effect of clipping treatment was satisfactory in 2 patients. One case was treated with remnant neck of aneurysms in order to protect perforating branches of artery. The blood flow was unobstructed in parent artery and distal artery. Patients were followed for 6 months to 2 years after surgery. The recovery was good. The patients' mRS (modified Rankin Scale) were 2, 0, 1, respectively. Barthel index [Activities of Daily Living (ADL)] were 65, 100, 95, respectively. There?fore the subtemporal approach is safe and effective in the treatment of basilar bifurcation aneurysm surgery.
