为探讨脑震荡经颅三维多普勒(3D-TCD)不同时期特点、参数,为该病临床诊断和判定治愈标准的评估提供一种无创、客观的检查方法,对135例脑震荡分别于24 h 内、3～7天和治疗终结采用3D-TCD 检测大脑中动脉(MCA)、基底动脉(BA)脑血流平均峰流速度(MVm)参数、频谱形态、特点,并与临床诊断和治愈标准进行比较分析。结果表明,在临床确诊的135例脑震荡中,3D-TCD 参数符合诊断101例,基本符合(临界值)12例,不符合22例(16.2%)。治疗终结,临床判定治愈96例(71.1%),好转39例(28.9%),而3D-TCD 判定符合治愈118例(87.4%),判定好转15例(17.8%)。结论:3D-TCD技术作为脑震荡诊断依据和治愈标准之一是可行的。本文提出了脑震荡所致脑血管痉挛的频谱特点、形态及参数。 In order to explore the features and parameters of different phases of 3D-TCD during concussion, we provide a non-invasive and objective examination method for the clinical diagnosis and judgment of the cure standard. h, 3 to 7 days and the end of treatment, 3D-TCD was used to detect the mean cerebral flow velocity (MVm) parameters, spectral shapes and characteristics of the middle cerebral artery (MCA) and basilar artery (BA) Standard for comparative analysis. The results showed that in the clinical diagnosis of 135 cases of concussion, 3D-TCD parameters consistent with the diagnosis of 101 cases, basically in line with the (critical value) in 12 cases, does not meet the 22 cases (16.2%). At the end of treatment, clinical judgment was cured in 96 cases (71.1%) and improvement in 39 cases (28.9%), while 3D-TCD was found in 118 cases (87.4%) and in 15 cases (17.8%) in 15 cases. Conclusion: 3D-TCD is one of the diagnostic criteria and cure criteria for concussion. This paper presents the spectrum characteristics, morphology and parameters of cerebral vasospasm induced by concussion.
