摘　　要：目的 :探讨经食道超声心动图 (TEE)及经胸壁超声心动图 (TTE)在探查心脏及主动脉弓潜在性栓塞源(PES)中的相对价值 ,并进一步了解主动脉弓动脉粥样硬化 (AAA)在缺血性中风中的作用。方法 :所有患者进行了TTE及TEE检查 ;同时对所有患者进行了颈动脉实时超声 ,TCD和CT检查 ,部分患者进行了DSA及MRI等检查。结果 :TTE不能发现主动脉弓病变 ;在TEE检查中 :31例 (63 % )在主动脉弓发现有动脉粥样硬化性病变。两者比较 ,TEE对心脏及主动脉弓的PES的发现率为 48.98% ,而TTE仅为 1 8.4%。结论 :TEE是目前探查主动脉弓及心脏PES的一个较好的检查手段。主动脉弓动脉粥样硬化在缺血性中风中非常常见 。Objective:The purpose of this study was to determine the relative value of Transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) on exploring the potential embolic source (PES) of heart and aortic arch, and further to study the clinical significant of AAA. Methods:Forty-nine consecutive patients with cerebral embolism were included in this study. We used TEE and TTE to evaluate potential source of emboli in aortic arch and heart, and duplex in carotid artery. Results: Of 49 patients, 31(63%) patients showed evidence of AAA;The potential sources of embolization of heart and aortic arch is 48.98% found by TEE,but only in 18.4% by TTE; 9 patients had heart disease; age and ICAA had significantly correlated with AAA. Conclusions:TEE is a better method to explore atherosclerotic lesion in the thoracic aorta at present. AAA is an important potential source of cerebral embolic stroke.
