作者就头颅CT扫描与卒中病因如心原性栓塞和颅外大动脉病变间关系对200例可逆性脑缺血和缺血性卒中病人进行了前瞻性研究。 患者年龄17～84岁,平均58.5岁,其中男122例,女78例。头颅CT扫描均在卒中发作后1周内进行。将CT扫描图象分为①软脑膜动脉梗塞;②小的深部梗塞(腔隙性梗塞);③低灌性(边缘带)梗塞;④未分类的缺血性损害和⑤正常。所有患者都经过颅外及经颅多普勒、经胸和经食道超声心动图以及心电图检查。根据检查结果将卒中机理分为3组。组
The authors prospectively studied 200 patients with reversible cerebral ischemia and ischemic stroke who had a relationship between head CT scan and the cause of stroke, such as cardiogenic embolism and extracranial arterial disease. Patients aged 17 to 84 years, mean 58.5 years, of which 122 were male and 78 female. Head CT scan were performed within 1 week after stroke onset. The CT scan is divided into ① leptomeningeal artery infarction; ② small deep infarct (lacunar infarction); ③ low irrigation (margin zone) infarction; ④ not classified ischemic damage and ⑤ normal. All patients underwent extracranial and transcranial Doppler, transthoracic and transesophageal echocardiography and electrocardiogram examination. According to the test results, stroke mechanism was divided into 3 groups. group
