Abstract:
Objective To study the diagnostic value of TCD and MRI in transient ischemic attack (TIA) of internal carotid artery system.Methods The clinic data was analyzed to contrast the relation of the clinic manifestation and the TCD and MRI results of 66 patients suffered from TIA of the internal carotid artery system.then chi-square test was adopted.Results In TIA interval, extensive hemodynamics changes were occurred in the intracranial arteries among 60 patients(90 9%), and 22 patients(33 3) presented different degrees of stricture on the corresponding symptom side, MRI test showed lacunar infarct or small infarct foci among 50 patients(75 8%), and ischemic leukoenporosis among 35 patients(53 5%). But the foci took a two-side distribution and were relatively symmetrical. No significant correlation existed between the symptom and the foci,and the positive rate of TCD did not show remarkable difference between the symptoms and the foci, and the positive ratio of TCD did not show remarkable difference whether the MRI infarct foci existed or not. Meanwhile, there were also no notable distinction between the stricture change of arteries in the corresponding symptom side with the infarct foci and that of arteries in the corresponding symptom side without the infarct foci.Conclusions TCD can find the change of arteries related in TIA of the internal carotid artery system, and can be used as routine and primary screening. While MRI may bear no special clinic significance to TIA of the internal carotid artery system, but it has localization meaning to CWS, a clinical subtype of TIA.
