【摘要】：目的探讨多普勒超声(TCD)检查对海南地区原住居民后循环缺血(PCI)的诊断价值。方法选800例PCI患者及100例健康者,采用TCD及CT血管成像(CTA)检查,探查双侧大脑后动脉(PCA)、双侧椎动脉(VA)、基底动脉(BA)的峰值血流速度(Vs)、平均血流速度(Vm)、舒张末期血流速度(Vd),记录动脉搏动指数(PI)及频谱形态变化特征。结果研究组TCD检查管腔闭塞32条,轻度狭窄272条,中度狭窄96条,重度狭窄16条;双侧VA、PCA、BA的PI值及右侧VA、BA的Vs值显著高于对照组,双侧PCA的Vd值显著低于对照组(P0.05);血流速度加快和减慢所占比例均显著高于对照组(P0.05)。结论 TCD与CTA具有高度一致性,TCD检查能为PCI的诊断、病情评估、治疗和预后提供依据。
[Abstract]:Objective to evaluate the diagnostic value of Doppler echocardiography (TCD) in posterior circulation ischemia (PCI) of native residents in Hainan area. Methods 800 patients with PCI and 100 healthy controls were selected. TCD and CT angiography were used to detect the peak blood flow velocity of bilateral posterior cerebral artery (TCD), bilateral vertebral artery (VA) and basilar artery (BA). Mean blood flow velocity (VMV), end-diastolic velocity (VDV), arterial pulsatility index (Pi) and spectral morphology were recorded. Results 32 lumen occlusions were examined by TCD in the study group. There were 272 cases of mild stenosis, 96 cases of moderate stenosis and 16 cases of severe stenosis. The Pi value of bilateral VACABA and the Vs value of right VABA were significantly higher than those of the control group, and the VD value of bilateral PCA was significantly lower than that of the control group (P0.05). The proportion of blood flow velocity acceleration and deceleration was significantly higher than that of control group (P 0.05). Conclusion TCD and CTA have a high consistency in the diagnosis and evaluation of PCI. Treatment and prognosis provide evidence.

【正文快照】： 缺血性脑血管病[1](ICVD)约占脑血管病的80%,后循环缺血(PCI)约占ICVD的20%[1]。PCI预后很差,是脑血管疾病的防治重点。本研究对海南地区原住居民PCI患者行TCD检查,为寻找PCI的无创诊断方法提供参考。1资料与方法1.1一般资料选择2014年1月至2015年12月本院收治的800例PCI患者
