摘要 1病例报告<br>  患者女,65岁,因活动后气促、乏力10 d入院。症状多在劳累及爬楼后出现,休息后自行缓解。无胸闷、胸痛、晕厥、黑蒙、咯血、双下肢水肿等症状。既往有可疑高血压病史,否认糖尿病、高脂血症病史,否认近期有外伤、手术史。入院前2d曾到当地医院就诊,运动试验活动5 min后不能坚持,结果提示:可疑阳性。入院血压144/90 mm Hg,心率75次/min,查体无阳性体征。超声心动图:左心房内径32 mm,左心室内径45 mm,右心室前后径20 mm,横径37.6 mm,右心房内径35.6 mm,室间隔厚度9.4 mm,左心室后壁厚度10 mm,EF 71%,FS 36%,三尖瓣轻度反流(4.1 cm2),压差55 mm Hg。胸片:双肺纹理增多,心胸比0.59。心电图:左前分支阻滞,多导联T波改变。血生化:BNP 263 pg/ml。 D-二聚体256μg/L。血气分析:PO267 mm Hg, SO294%,PCO235.3 mm Hg。血常规、甲状腺功能、血糖、肝功、肾功、心肌酶谱、尿常规、大便常规正常。初步诊断:(1)冠状动脉粥样硬化性心脏病?(2)肺动脉高压待查?查肺功能:肺通气功能正常,小气道功能正常,支气管舒张试验阴性。下肢血管超声:双侧股总动脉粥样硬化斑块形成。肺血管CTA:双侧肺动脉栓塞,右侧为重,右侧肺动脉主干受累,左侧肺动脉分支部分支受累。诊断:肺栓塞(见图1)。立即予尿激酶20000 U/kg/2 h静脉滴注溶栓,低分子肝素注射液0.4 ml 皮下2次/d,华法林1.25 mg口服1次/d抗凝。溶栓后2 h:D-二聚体2589μg/L, INR 1.14。血气分析:PO281 mm Hg,SO297%。溶栓后3 d:超声心动图:左心房内径33 mm,左心室内径48 mm,右心室横径36 mm,右心房内径37 mm,室间隔厚度10 mm,左心室后壁厚度10 mm,EF 65%,FS 36%,三尖瓣局限性反流(2.9 cm2)。溶栓后4 d:D-二聚体465μg/L, INR 0.93。加大华法林剂量为2.5 mg 口服1次/d。溶栓后7 d:肺血管CTA:右肺动脉主干及其分支血管以及左肺动脉局部小分支血管栓塞,较前好转。溶栓后8 d:D-二聚体472μg/L,INR 1.09。加大华法林剂量为3.75 mg口服1次/d。溶栓后21 d:D-二聚体443μg/L, INR 3.04,血气分析:PO2104 mm Hg, SO298%。
