经食道心脏超声在心源性栓塞性脑梗死诊断中的应用

Application of transesophageal echocardiography in the diagnosis of patients with cardio-embolic cerebral infarction

目的探讨经食道心脏超声(TEE)和经胸壁心脏超声(TTE)在心源性栓塞性脑梗死(CES)诊断中的价值。方法以在本院接受诊断的46例隐源性青年脑梗死患者为研究对象,全部患者均经头颅MRI诊断为急性脑梗死,并均进行TEE和TTE检测,对比两种诊断数据,分析两种不同诊断技术的价值。结果采用TEE共检出CES患者15例(占32.6%),采用TTE共检出CES患者4例(占8.7%),TEE的检出率明显高于TTE,差异有统计学意义(χ2=8.02,P<0.01)。结论 TEE在诊断CES中有明显优势,具有重要的临床应用价值。

Objective To explore the diagnostic value of transesophageal echocardiography （TEE） and transthoracic e- chocardiography（TTE） for patients with cardio-embolic cerebral infarction（CES）. Methods 46 cases of young patients with cryptogenic infarction in our hospital were selected as the experiment object.All the patients were diagnosed as a- cute cerebral infarction by cranial MRI.All the 46 patients were tested with TEE and TFE to compare the diagnostic data for the analysis of the value of the two different diagnostic techniques. Results 15 patients （accounted for 32.6%） with CES were diagnosed by TEE,and 4 patients （accounted for 8.7%） were diagnosed by TEE.The detection rate of TEE was obviously higher than that of TTE,the difference was statistically significant （X^2=8.02,P〈0.01）. Conclusion TEE has obvious advantages in the diagnosis of CES,which has important clinical application value.
