摘要 患者男,60岁,体质量65 kg。2014年1月突然出现活动后胸闷、心悸,休息后缓解,自此后症状反复发作并逐步加重。入院前步行20米即感胸闷、气促、乏力,夜间不能平卧并伴双下肢水肿。入院后胸部X线检查示心胸比例0.70,呈普大型,两肺纹增多,主动脉迂曲,上纵隔影增宽(图1)。超声心动图示主动脉直径69 mm,室间隔厚11 mm,左心室后壁厚11 mm,左心室舒张末期内径77 mm,左心室收缩期内径69 mm,左心室射血分数(EF)0.22,短轴缩短分数(FS)0.11,主动脉瓣回声增强伴中度反流,二、三尖瓣中、轻度反流,心包腔少量积液,主动脉全程增宽,主动脉根部、升主动脉及主动脉弓内均探及飘动内膜回声,将管腔分为真假两腔。 CTA显示升主动脉夹层,累及主动脉弓、无名动脉及左锁骨下动脉,左颈总动脉闭塞(图2)。右心导管监测肺血管阻力5.5 wood。肝肾功能中、轻度受损,经治疗后基本恢复。术前诊断:扩张型心肌病、Stanford A 型主动脉夹层,心功能Ⅳ级。拟行全心脏、升主动脉及主动脉弓移植、降主动脉支架置入手术。
