摘要
目的探讨利用超声检查脑卒中患者升主动脉和主动脉弓斑块的意义。方法 52例经核磁共振或电子计算机X射线断层扫描技术证实脑内存在急性或亚急性栓塞灶的患者,经食管和经胸超声心动图分别检测升主动脉和主动脉弓。了解出现在升主动脉和主动脉弓的斑块情况。结果经胸超声心动图发现斑块位于升主动脉者18例,共20个斑块;经食管超声心动图发现斑块位于升主动脉者23例,共27个斑块。经胸和经食管超声心动图同时发现斑块位于升主动脉者16例,共18个斑块,其中不稳定斑块5个。经胸超声心动图发现斑块位于主动脉弓者29例,共43个斑块;经食管超声心动图发现斑块位于主动脉弓者40例,共58个斑块。经胸和经食管超声心动图同时发现斑块位于主动脉弓者25例,共35个斑块,其中不稳定斑块18个。经食管超声心动图发现的斑块数量多于经胸超声心动图。结论结合经食管超声心动图,可以避免经胸超声心动图图像显示不清的缺点,提高急性脑卒中患者大血管病变的阳性检出率,并有助于斑块性质的描述,为急性脑卒中患者血管源性栓子来源提供依据。
Objective To investigate the plaque in ascending aorta and aortic arch by ultrasound in patients with the stroke.Methods Fifty-two patients with magnetic resonance(MR) or X-ray computer tomography(CT) confirmed the presence of acute or subacute stroke,looking from the ascending aorta and aortic arch of vascular plaque by transesophageal and transthoracic echocardiography.The ascending aorta and aortic arch plaques were detected.Results There were 18 cases with a total of 20 plaques in the ascending aorta found by transthoracic echocardiography.There were 23 cases with a total of 27 plaques in the ascending aorta found by transesophageal echocardiography.There were 16 cases with a total of 18 plaques in the ascending aorta found by transthoracic and transesophageal echocardiography,including 5 unstable plaques.There were 29 cases with a total of 43 plaques in the aortic arch found by transthoracic echocardiography.There were 40 cases with a total of 58 plaques in the aortic arch found by transesophageal echocardiography.There were 25 cases with a total of 35 plaques in the aortic arch found by transthoracic and transesophageal echocardiography,including 18 unstable plaques.Transesophageal echocardiography showed the plaque number more than the transthoracic echocardiography results.Conclusions If combining transesophageal and transthoracic echocardiography,the shortcoming of showing unclear image shoud be avoided.The positive rate of large vascular disease in acute stroke patient will be increased.It is important of description of plaque for the diagnosis of acute stroke in patients that we find the emboli basis with large vascular sources.
