作者以46例急性心原性脑栓塞病人为对象(设30例对照组),通过双侧颈内动脉造影,双侧颈总动脉多普勒超声检查进行对比研究,旨在确定能否通过测定颈总动脉舒张末期血流速度识别心原性栓子所致颈动脉系统血管闭塞的部位。46例急性心原性栓塞病人均于发病7天内,在同一天完成血管造影及多普勒超声检查。运用多普勒超声检查测定颈总动脉舒张末期血流速度,并计算双侧颈总动脉舒张末期血流速度比率(ED 比率)。
The author of 46 cases of acute cardioembolic patients as the object (set 30 cases of control group), bilateral carotid artery angiography, bilateral common carotid artery Doppler ultrasound comparative study to determine whether the determination of whether End-diastolic velocity of the common carotid artery identifies sites of carotid vascular occlusion caused by cardiogenic emboli. Forty-six patients with acute cardioembolism underwent angiography and Doppler ultrasonography on the same day within 7 days of onset. Doppler echocardiography was used to measure the end-diastolic blood flow velocity of the common carotid arteries and the ratio of end-diastolic blood flow velocity (ED) was calculated.
