- W3030185317 abstract "Objective To evaluate the diagnostic value of digital subtraction angiography （DSA） and carotid artery ultrasound for transient ischemia attack （TIA）. Methods Among the 74 patients with TIA, 45 had internal carotid artery （ICA）-TIA and 29 had vertebrobasilar artery （VBA）-TIA. DSA examination was performed in order to detect intracranial and extracranial arterial stenosis in the above two systems. Cervical artery ultrasound examination was used to understand the distribution of arterial plaques. Results DSA showed that the detection rate of vascular stenosis in patients with ICA-TIA was 84.4% （n =38）, and the patients with serious, moderate and slight stenoses were 31.1% （n = 14）, 26.7% （n = 12） and 11.1% （n = 5）, respectively. Of those, intracranial arterial stenosis was 44.4% （n = 20）, and it was significantly higher than 22.2% （n = 10） in extracranial arterial stenosis （P 〈 0. 001 ）; the detection rate of vascular stenosis in patients with VBA-TIA vcas 65.5% （n = 19）, and the patients with serious, moderate and slight stenoses were 17.2% （n = 5）, 27.5% （n = 8）, and 20.7% （n = 6）, respectively. Of those, extracranial arterial stenosis was 44. 8% （n = 13）, and it was significantly higher than 13.8% （n = 4） in intracranial stenosis （P 〈 0. 001 ）. Carotid artery ultrasound showed that the detection rate of ICA plaque was 44.4% （n = 20）, and it was higher than 24. 1% （n = 7） in patients with VBA-TIA; the detection rate of the plaques in the initial segment of subelavian artery in patients with VBA-TIA was 44.8% （n = 13）, and it was significantly higher than 13.3 % （n = 6） in patients with ICA-TIA （P 〈 0.001 ）. Conclusions There were differences between the intracranial and extracranial vascular lesions and the distribution of atherosclerotic plaques in patients with ICA-TIA and VBA-TIA. The former was more common in intracranial lesions, and the latter was more common in extracranial lesions.Key words: transient ischemic attack; digital subtraction angiography; ultrasonography" @default.
