摘要
目的探讨颞窗超声检查对脑梗死患者大脑中动脉病变的诊断价值。方法选择2009年1月～2010年1月经临床及CT或MRI诊断的23例脑梗死,选取经颞窗可清晰显示的37根大脑中动脉进行观察,记录其病变情况,并与磁共振动脉成像(MRA)结果进行比较。结果颞窗超声检查对大脑中动脉病变的检出率为73.0%,MRA检查对大脑中动脉病变的检出率为81.1%,两者比较差异无统计学意义(χ2=1.33,P>0.05)。结论对脑梗死患者行颞窗超声检查可清楚观察大脑中动脉病变情况,对指导临床治疗及提示预后很有意义。
Objective To evaluate the value of ultrasonograph through temporal window in diagnosis of middle cerebral artery pathological changes of the patients with cerebral infarction.Methods 23 patients were diagnosed as cerebral infarction by CT or MRI detection from January 2009 to January 2010,and 37 middle cerebral arteries were clearly displayed through temporal window and changes were recorded and compared with magnetic resonance angiography.Results The pathological change rate of middle cerebral artery detected by ultrasonograph through temporal window was 73.0% and 81.1% by magnetic resonance angiography.The difference was not statistically significant（χ2=1.33,P0.05）.Conclusion Ultrasonograph can display the pathological changes of middle cerebral artery clearly and provide significant information for the treatment and prognosis to those patients with cerebral infarction.
