Abstract:
Objective To investigate the dynamic changes of cerebral blood flow defined bytranscranial color Doppler (TCD) and their correlation with the severity and prognosis of acute ischemicstroke. Methods Fifty-six consecutive patients with the primary onset of acute ischemic strokereceived dynamic examinations with TCD upon admission and on days 2, 4, 7, 14 and 28 following theonset, and the mean blood flow velocity and pulsatility index were recorded. Results TCDexaminations upon admission revealed high abnormal rate. The mean blood flow velocity of the middlecerebral artery (VmMCA) on the lesion side was significantly lower than that on the contralateral side andthat of the control group. The blood flow velocity of the anterior cerebral artery (VmACA) on the lesion sidewas significantly increased compared with that on the contralateral side and that of the control group.VmMCA of main stem occlusion group {23.45 [7.55,38.72] cm/s}, central branch infarction group {52.53[45.56,66.93] cm/s}, and cortical branch of cerebral arteries infarction group {38.44[31.67,52.45] cm/s}was significantly lower than that of the control group {66.51 [56.64,71.43] cm/s}. VmMCA graduallyincreased in these patients after the treatment, showing significant difference from that measured uponadmission. The PI of the middle cerebral artery increased after admission, with significant difference fromthat recorded on admission and that of the control group. Conclusion TCD has high diagnostic valuefor ischernic stroke and may help evaluate the severity of the condition and the prognosis of the patients.
