采用脑血管血液动力学检测仪对５６例颈内动脉系统缺血性脑血管病患者发病初期的脑血管血液动力学指标（ＣＶＤＩ）进行了全面系统的观察与分析，并与ＣＴ、ＭＲＩ、ＤＳＡ等影像学检查相对照。其中急性脑梗塞（ＡＣＩ）３８例，短暂性脑缺血发作（ＴＩＡ）１８例。结果发现：①绝大多数患者病灶侧大脑半球总供血量及血流速度明显下降，脑血管阻力及临界压力升高，脑动脉弹性下降及脑血流自动调节功能衰退。②ＣＶＤＩ对于ＡＣＩ的早期（２４小时以内）诊断比ＣＴ更敏感，阳性率为９０％、１５％，说明ＣＶＤＩ的改变早于形态学的改变。③无论梗塞灶大小，ＣＶＤＩ轻度异常者，预后良好；ＣＶＤＩ严重异常者，预后均较差（Ｐ＜０．０１）。我们认为：ＣＶＤＩ的上述规律性变化，对于急性缺血性脑血管病的诊断、判定治疗效果及推测预后等均有重要的参考价值。
Fifty-six cerebral vascular hemodynamic parameters (CVDI) in patients with carotid artery ischemic cerebrovascular disease at the early stage of onset were systematically observed and analyzed by using a cerebrovascular hemodynamic analyzer. CT-MRI, DSA Such as imaging contrast. There were 38 cases of acute cerebral infarction (ACI) and 18 cases of transient ischemic attack (TIA). The results showed that: (1) The vast majority of patients had lesser hemispheric total blood supply and blood flow velocity, increased cerebral vascular resistance and critical pressure, decreased cerebral arterial elasticity and cerebral blood flow auto-regulation. (2) CVDI was more sensitive to CT than CT in the early (within 24 hours) diagnosis of ACI, the positive rate was 90% and 15%, indicating that the change of CVDI was earlier than the change of morphology. ③ regardless of infarct size, mild CVDI abnormal prognosis; CVDI serious abnormalities, the prognosis was poor (P <0.01). In our opinion, the above regular changes of CVDI have important reference value for the diagnosis of acute ischemic cerebrovascular disease, the judgment of therapeutic effect and the prediction of prognosis.
