摘要 患者男,57岁,体重65 kg,因“突发昏迷3d”急诊入院.术前诊断:(1)小脑大面积梗死,脑积水.(2)重度退行性主动脉瓣狭窄合并轻中度关闭不全,心功能Ⅱ级.(3)冠状动脉粥样硬化性心脏病,三支病变,无症状性心肌缺血.(4)高血压3级,极高危组.(5)发热待查.拟于静吸复合麻醉下急诊行“开颅去骨瓣减压+脑室外引流+气管切开术”.术前检查:浅昏迷,双侧瞳孔等大等圆,对光反射减弱.听诊主动脉瓣第一、二听诊区可闻及3/6级收缩期粗糙杂音,向颈部传导.头颅CT:小脑大面积梗死,脑积水.冠状动脉CT:冠状动脉粥样硬化,左前降支狭窄10%,左回旋支狭窄85%,右冠状动脉狭窄60%~ 70%.心脏瓣膜病,主动脉瓣损害,升主动脉增宽.心脏彩超:主动脉瓣重度狭窄伴轻中度关闭不全,升主动脉增宽;主动脉瓣口面积0.9 cm2,收缩期跨瓣压差86 mm Hg(1 mm Hg =0.133 kPa),舒张期跨瓣压差101 mm Hg,左室饱满,左房扩大;室间隔、左室壁增厚,左室射血分数54%.患者因心脏病变准备行“主动脉瓣置换+CABG+升主动脉探查术”,术前突发昏迷,发热(T42℃),故需急诊行开颅手术.化验检查:WBC 26.19×109/L.
