采用经颅多普勒超声仪(TCD)对54例急性脑梗塞患者进行了检测,同时进行头颅 CT 检查以资比较。根据急性脑梗塞后时间不同,TCD 有如下表现:(1)无血流信号,8例,均为大脑中动脉闭塞,CT 上表现为大面积脑梗塞,(2)血流速度降低,28例,包括血流速度绝对降低与相对降低两种情况,(3)血流速度增快,12例,见于病程3～7天后的患者,(4)侧副信号增强型,22例,常与一、二型合并存在,(5)大致正常,6例,见于腔隙梗塞。TCD 为脑血管病的诊断,研究提供了一种新方法。
Fifty-four patients with acute cerebral infarction were examined by transcranial Doppler (TCD), and CT scans were performed for comparison. According to the different time after acute cerebral infarction, TCD has the following manifestations: (1) no blood flow signal, 8 cases were middle cerebral artery occlusion, CT showed large area cerebral infarction, (2) blood flow velocity decreased, 28 cases , Including absolute decrease and relative decrease in blood flow velocity, (3) faster blood flow, 12 patients seen in patients with disease duration of 3 to 7 days, (4) enhanced side accessory signal, 22 patients, often with one , Type two merged, (5) roughly normal, 6 cases, found in lacunar infarction. TCD provides a new method for the diagnosis and research of cerebrovascular disease.
