缺血性脑卒中患者MCA血流速度及脉动指数变化的相关分析

摘要

Objective To investigate cerebral ischemic stroke patients MCA blood flow velocity and pulsatility index. Methods A total of 120 patients with ischemic stroke were slected in the department outpatient and inpatient hospital of First Affiliated Hospital of Jiamusi University from January 2016 to January 2017, including 56 cases of male, female 64 cases. The transcranial oppler ultrasound use to test patients bilateral middle cerebral artery and detected blood flow velocity and pulsatility index .The changes of blood flow velocity and pulsatility index in the middle cerebral artery of the affected side and the healthy side were . Results All of patients with the affected side middle cerebral artery systolic peak flow velocity (t=15.63, P＜0.05), diastolic peak flow velocity (t=10.61,P＜0.05) was smaller than the contralateral side; and the affected side average blood flow velocity compared with the contralateral side was not statistically significant (t=0.58,P＞0.05); and for cerebral artery the affected side pulsatility index are significantly higher than the contralateral (t=3.54, P＜0.05).Conclusion The cerebral ischemic stroke patients with cerebral infarction in the middle cerebral artery, the clinical observation of TCD in patients with middle cerebral artery blood flow velocity and pulsatility index of the clinical diagnosis and treatment, predict the change of the disease has guiding significance.%目的 探讨并分析缺血性脑卒中患者MCA血流速度及脉动指数的变化.方法 选取2016年1月-2017年1月就诊于佳木斯大学附属第一医院神经三科门诊及住院部的120例缺血性脑卒中住院患者,其中男性56例,女性64例.使用经颅多普勒超声诊断仪探查患者双侧大脑中动脉,测出患者大脑中动脉的血流速度和脉动指数.比较所有患者患侧与健侧的大脑中动脉血流速度和脉动指数变化.结果 所有患者患侧大脑中动脉收缩期最快血流速度(t=15.63,P＜0.05)、舒张期最快血流速度(t=10.61,P＜0.05)明显小于健侧;而平均血流速度患侧与健侧比较无统计学意义(t=0.58,P＞0.05);并且大脑中动脉供脉动指数值明显高于健侧(t=3.54,P＜0.05).结论 缺血性脑卒中患者大脑中动脉供血区脑梗死,临床进行TCD观察患者大脑中动脉血流速度及脉动指数的变化的临床诊疗,预判病情变化有指导意义.
