Background and Purpose: To evaluate the blood flow velocity using doppler ultrasound of the carotid artery, vertebral artery, and basilar artery in stroke patients
Material and Methods: To evaluate the blood flow, I measured the peak systolic velocity and mean velocity of the common carotid artery(CCA), internal carotid artery(ICA), external carotid artery (ECA). vertebral artery(VA), and basilar artery(BA) in 44 stroke patients and 15 healthy adults. To investigate the difference between ischemic stroke patients and normal healthy adults, I selected 44 ischemic stroke patients diagnosed by brain CT and brain MRI, and 15 healthy adults who did not have any symptoms of stroke, hypertension, heart disease, and diabetes melitus.
Results: Peak velocity in normal adults was 50.6{pm}1.6cm/sec in the CCA, 67.2{pm}1.7cm/sec in the ICA, 62.5{pm}2.4cm/see in the ECA, 45.5{pm}1.9cm/sec VA. and 50.5{pm}3.5cm/sec in the BA. Mean velocity in normal adults was 26.9{pm} 1.1cm/sec in the CCA, 43.7{pm}1.4cm/sec in the ICA, 26.7{pm}1.3cm/sec in the ECA. 31.6{pm}1.9cm/sec in the VA and 33.0{pm}2.6cm/sec in the BA. In this study, there was a significant increase in the velocity of ICA, ECA, and VA of ischemic stroke patients in comparison with normal healthy adults. And the blood flow velocity of this study in the CCA and ECA was different from other reported foreign values and the other known values in my country.
Conclusion: There was a significant difference in the blood flow velocity between ischemic stroke patients and normal healthy adults. And the blood flow velocity of this study was different from other reported foreign values and the other known values in my country. Therefore, it needs more detailed studies about old aged Korean and ischemic stroke patients than previous studies.
