摘要 患者女,59岁,因“突发意识障碍1h”于2012年10月收入江苏省苏北人民医院神经外科。既往有“高血压病史”20余年,规律服用降压药,血压维持平稳。入院时意识呈浅昏迷,格拉斯哥昏迷量表(GCS)评分6分,Hunt-Hess分级Ⅳ级。头部CT检查提示,鞍上池、纵裂池、双侧侧裂池见条状高密度影,双侧侧脑室后角见少量积血(图1a)。头部CTA检查提示,左侧后交通动脉起始处见瘤样突起,约为12.3mm×5.2mm(图1b,1c)。患者在入院后2h接受“开颅夹闭动脉瘤”手术。经左侧翼点入路,在外科显微镜下开放额叶蛛网膜及视交叉池,缓慢释放脑脊液,使脑压逐步下降。剪开侧裂和蛛网膜及颈动脉池蛛网膜,显露左侧颈内动脉,探查见左侧床突上段后下方动脉瘤(图1d)。暴露瘤颈过程中,发生动脉瘤颈破裂出血,血流汹涌,通过双吸引器保证术野清楚(1支吸引器对准破裂口,另1支清除瘤体周围血液)。
