【摘要】：目的 :探讨用TCD(经颅多普勒超声)诊断双颈内动脉颅外段闭塞的临床效果。方法 :对近年来我院收治的30例急性脑梗死患者和在我院体检中心进行健康体检的30名健康人的临床资料进行回顾性研究。将这30例急性脑梗死患者作为脑梗死组,将这30名健康人作为健康组。这30例脑梗死患者的病情经DSA(数字减影血管造影检查)或MRA(磁共振血管成像检查)后,均被确诊为双颈内动脉颅外段重度狭窄或闭塞。使用TCD对两组研究对象双侧的MAC(大脑中动脉)、PAC(大脑后动脉)和ACA(大脑前动脉)的PSV(收缩期峰值流速)和PI(血管搏动指数)进行检查。然后,观察两组研究对象颈内动脉的血流参数及其超声图像的特点。结果:脑梗死组患者颈内动脉的血流参数与健康人相比具有显著的不对称性,且其患侧MCA、ACA的超声图像表现为波浪形圆钝血流频谱改变。结论 :用TCD诊断双颈内动脉颅外段闭塞的效果显著,可准确检测出患者颈内动脉颅外段重度狭窄或闭塞的情况,为临床上诊断缺血性脑卒中提供准确的参考依据。
[Abstract]:Objective: to explore the use of TCD (transcranial Doppler ultrasound). Clinical effect of diagnosis of bilateral internal carotid artery extracranial occlusion methods:. The clinical data of 30 patients with acute cerebral infarction treated in our hospital and 30 healthy people who underwent physical examination in our physical examination center in recent years were retrospectively studied. The 30 patients with acute cerebral infarction were treated as cerebral infarction. Group. These 30 healthy people were used as the healthy group. The patients with cerebral infarction were examined with DSA (digital subtraction angiography) or MRA-MRA (magnetic resonance angiography). All patients were diagnosed as severe stenosis or occlusion of the extracranial segment of the internal carotid artery. TCD was used to study the bilateral middle cerebral artery (MCA) in both groups. PSV (peak systolic velocities) and Pi (pulsatility index) of PACand ACAA (anterior cerebral artery) were examined. Then. Results: the blood flow parameters of the internal carotid artery in the patients with cerebral infarction were significantly asymmetrical compared with those of the healthy subjects, and the MCA of the affected side was significantly different from that in the patients with cerebral infarction. ACA showed the change of blood flow spectrum in wavy circle. Conclusion: the diagnosis of bilateral internal carotid artery extracranial occlusion by TCD is very effective. It can accurately detect the severe stenosis or occlusion of the extracranial segment of the internal carotid artery and provide an accurate reference for the clinical diagnosis of ischemic stroke.

【正文快照】： 颈内动脉颅外段出现重度狭窄或闭塞是导致缺血性脑卒中的重要原因。缺血性脑卒中患者侧支循环代偿的情况与其缺血性症状的发生有直接的联系。有研究表明,TCD属于无创检查方法,此检查方法可直接观察到患者颅内血流动力学变化的情况,为临床上诊断缺血性脑卒中提供准确的参考依据
