经食管超声心动图诊断心脑卒中的意义

The Diagnostic Sense for Cardiac Sources of Embolism by Transesophageal Echocardiography

目的 研究经食管超声心动图TEE及经胸超声心动图TTE对心源性脑卒中诊断的临床意义。方法 对6 4例缺血性脑卒中患者及 6 0例非脑卒中对照者进行TEE及TTE检测。结果 TEE与TTE比较 ,心脑卒中因素检出率 (40例 / 13例 ,P <0 .0 1)。脑血管病组与对照组比较 ,TEE心脑卒中因素检出率 (2 7例 / 13例 ,P <0 .0 1)。经TEE探查有心脑卒中因素者与无心脑卒中因素者比较 ,年龄 (6 7.5 / 5 7.4岁 ,P <0 .0 5 ) ,心房颤动 (18/ 10例 ,P <0 .0 1) ,主动脉活动性斑块 (5 / 0例 ,P <0 .0 1)。结论 脑缺血发作患者 ,TEE探查潜在心脑卒中因素较TTE更敏感。

Objective To study the diagnostic yields of transesophageal and transthoracic echocardiography (TEE and TTE) in the detection of cardiac sources of embolism. Methods 64 patients suffered from ischemic stroke and 60 subjects were out of stroke as healthy controls, those were detected by TEE and TTE. Results 40 cases with cardiac sources of embolism were detected by TEE and 13 by TTE(40 vs 13, P <0.01). There is significantly different in detecting cardiac sources of embolism by TEE between the cerebral ischemic group and controls (27 vs 13, P <0.01). All subjects were examined by TEE. One group is with cardiac sources of embolism, while the other group is without. Which had significant difference in age(67.5 vs 57.4, P <0.05), atriofibrolation (18 vs 10, P <0.01), and aortic plaque (5 vs 0, P <0.01). Conclusion TEE is more sensitive in the detection of potential cardiac sources of embolism than TTE is. [
