选择５４例动脉粥样硬化性血栓性脑梗塞（ＡＴＣＩ）早期临床表现不典型的病例对其早期（发病２４小时内）ＴＣＤ、ＣＴ检查进行回顾性对比研究，结果表明ＴＣＤ异常率（８３．３％）明显高于ＣＴ异常率（５．６％）。ＴＣＤ异常中以血管狭窄为主，以ＭＣＡ受累最多。提示ＴＣＤ能及时提供脑血液动力学变化，弥补了ＣＴ对ＡＴＣＩ早期诊断的不足。临床上对无明显定位体征而ＴＣＤ提示脑血管狭窄的病例，需警惕ＡＴＣＩ的可能。
54 patients with atherosclerotic thrombotic cerebral infarction (ATCI) were selected to retrospectively study the early stage (within 24 hours) of TCD and CT examination. The results showed that the abnormal rate of TCD (83.3 %) Was significantly higher than CT abnormal rate (5.6%). TCD abnormalities mainly vascular stenosis, with MCA involvement most. Tip TCD can provide timely cerebral hemodynamic changes, to make up for the lack of CT on the early diagnosis of ATCI. Clinically there is no obvious signs of positioning and TCD prompt cerebral vascular stenosis cases, need to be alert to the possibility of ATCI.
