[摘要] 目的 研究因脑血管疾病入院的患者的脑血管狭窄程度与经颅多普勒超声(transcranial doppler,TCD)测试得出的血流速度之间的关系,从而为该疾病的治疗做出一定的贡献。方法 方便选取该院接收的60例因脑血管疾病入院的患者,该次实验研究的时间范围为2017年7月—2019年7月,对这些患者分别采用数字减影血管造影检查与多普勒超声检查,将两种检查方法的从检查结果进行对比。结果 狭窄组年龄(63.68±10.09)岁、高血压28例、糖尿病15例均高于非狭窄组,两组比较差异有统计学意义(t=4.320,P<0.05;χ2=23.254、11.429,P<0.05)。TCD对脑血管狭窄血管病变的检测当中,数值较高,患者的血管狭窄程度越严重,患者的平均血流速度越快,不同血管狭窄程度之间的患者平均血流速度之间的差异有统计学意义(P<0.05),平均血流速度与相应的血管的狭窄率之间有明显的的正相关关系。结论TCD测试得出的血流速度与患者的血管狭窄程度之间具有明确的相关性,可以通过患者的血流速度来判断患者的血管狭窄程度,具有重要的临床诊断价值以及诊断意义,效果显著。

[Abstract] Objective To study the relationship between the degree of cerebrovascular stenosis and the blood flow velocity obtained from transcranial Doppler (TCD) tests in patients admitted for cerebrovascular disease, so as to make the treatment for the disease A certain contribution. Methods A total of 60 patients admitted to the hospital for cerebrovascular disease were convenient selected. The time range of this experimental study was from July 2017 to July 2019. Digital subtraction angiography and Doppler ultrasound examination compares the results of the two examination methods. Results The age of stenosis group (63.68±10.09) years, 28 cases of hypertension, and 15 cases of diabetes were higher than those of non-stenosis group. The difference between the two groups was statistically significant(t=4.320, P<0.05; χ2=23.254, 11.429, P<0.05). In the detection of cerebrovascular stenosis and vascular lesions by TCD, the higher the value, the more severe the vascular stenosis of the patient, the faster the average blood flow velocity of the patient, and the difference between the average blood flow velocity of the patients with different degrees of vascular stenosis was statistically significant(P<0.05). There was a clear positive correlation between the mean blood flow velocity and the stenosis rate of the corresponding blood vessels. Conclusion There is a clear correlation between the blood flow velocity obtained by TCD test and the degree of vascular stenosis of the patient. The degree of vascular stenosis of the patient can be judged by the patient's blood flow velocity. It has important clinical diagnostic value and diagnostic significance, and has significant effects.

近些年来,我们国家的老龄化人口正在逐年增长,伴随着老龄化人口的不断增加,脑梗死这一疾病的发病率正在逐年提升。脑梗死这一疾病目前已经成为严重危害中老年身体健康以及生活质量的主要脑血管疾病,有效诊断出该疾病,对該疾病的治疗起着至关重要的作用[1-3]。数字减影血管造影(digital subtraction angigography,DSA)是诊断脑血管疾病的重要诊断方法,但是这种诊断方法的费用较高,操作较为复杂,而且会对患者带来一定的创伤。在临床应用上多有不便,经颅多普勒超声检查是利用多普勒效应研究患者脑底动脉血流动力学的一种新型无创性检测技术,这种检测技术相比于以往的DSA,具有无创性、价格低廉、操作简单、用时较短等优点[4-8]。该文从这种检查技术出发,探讨了TCD血流速度与患者的脑血管狭窄程度之间的关系,并进行了相关的实验研究,该次实验研究对象为60例脑血管患者,研究时间为2017年7月—2019年7月,现报道如下。……
