Carotid atherosclerosis is often mentioned as one of the main causes of stroke. Currently, embolization is considered the most common mechanism that causes ischemic strokes due to atherosclerotic lesions in the carotid artery. Transcranial Doppler (TCD) ultrasound provides relatively inexpensive, noninvasive, real-time measurement of blood flow characteristics and cerebrovascular hemodynamics within brain arteries. The pulsatile index measured by transcranial Doppler is a parameter that indicates the degree of elasticity of the blood vessels of the brain.
The aim of this study is to determine the relationship between the value of the pulsatile index of the middle cerebral artery and the basilar artery in patients with carotid stenosis using transcranial Doppler and the value of the pulsatile index in relation to the degree of carotid stenosis.
The study involved a total of 140 patients examined at the Color Doppler and Transcranial Doppler Department of the Neurology Department of the General Hospital "Prim Dr. Abdulah Nakas" Sarajevo The patients were divided into two groups. The research was conducted in the General Hospital "Prim. dr. Abdulah Nakas" in Sarajevo at the Department for Color Doppler and Transcranial Doppler of the Department of Neurology and included patients examined in the period from February 2022 to December 2022. All patients underwent extracranial Doppler of the carotid arteries and transcranial Doppler of the middle cerebral artery and basilar artery.
The mean values of PI in ACM in the total sample were statistically significantly lower in patients with stenosis up to 50% compared to the average in patients with stenosis over 50%. Average values of PI in AB in the total sample were statistically significantly lower in patients with stenosis up to 50% compared to the mean values in patients with stenosis over 50%.
Transcranial Doppler findings showed an increased pulsatile index in patients who had carotid stenosis greater than 50% compared to patients with mild carotid stenosis. The study showed that in clinical work it would be necessary to introduce the pulsatile index as an indispensable neurosonological parameter that would be included in the findings of the transcranial Doppler and thus objectify the potential risk of a cerebrovascular ischemic event.
颈动脉粥样硬化常被提及为中风的主要原因之一。目前，栓塞被认为是颈动脉粥样硬化病变导致缺血性中风的最常见机制。经颅多普勒（TCD）超声能相对廉价、无创地实时测量脑动脉内的血流特征和脑血管血流动力学。经颅多普勒测量的搏动指数是一个表明脑动脉血管弹性程度的参数。
本研究的目的是使用经颅多普勒确定颈动脉狭窄患者大脑中动脉和基底动脉搏动指数值与颈动脉狭窄程度之间的关系。
该研究共纳入了140名在萨拉热窝“阿卜杜拉·纳卡斯博士总理医院”神经内科彩色多普勒和经颅多普勒科室接受检查的患者。患者被分为两组。研究在萨拉热窝“阿卜杜拉·纳卡斯博士总理医院”神经内科彩色多普勒和经颅多普勒科室进行，纳入了2022年2月至2022年12月期间接受检查的患者。所有患者均接受了颈动脉颅外多普勒检查以及大脑中动脉和基底动脉的经颅多普勒检查。
在总样本中，狭窄程度高达50%的患者大脑中动脉PI的平均值与狭窄程度超过50%的患者相比，在统计学上显著更低。在总样本中，狭窄程度高达50%的患者基底动脉PI的平均值与狭窄程度超过50%的患者相比，在统计学上显著更低。
经颅多普勒检查结果显示，与轻度颈动脉狭窄患者相比，颈动脉狭窄大于50%的患者搏动指数升高。该研究表明，在临床工作中，有必要引入搏动指数作为一个不可或缺的神经超声参数，将其纳入经颅多普勒检查结果中，从而客观评估脑血管缺血事件的潜在风险。
