Correlation between clinical manifestation and cerebral artery stenosis in transient ischemic attack patients

Objective To investigate the correlation between cerebral artery stenosis and transient ischemic attack (TIA). Methods 53 TIA patients from Nanjing Stroke Registry were studied. The occurrence of cerebral artery stenosis in patients was assessed. Results Cerebral artery stenosis or occlusion were found in 39 patients. Among them 13 cases had extracranial artery stenosis, 11 patients had intracranial artery stenosis and 15 patients had both extracranial and intracranial artery stenosis. 14 patients showed normal image. 22 out of 32 patients with anterior circulation TIA had anterior circulation stenosis (68.8%). 8 out of 21 patients with posterior circulation TIA had posterior circulation stenosis (38.1%). The occurrence of stenosis was significant difference between two groups(P 0.05) . Conclusion The occurrence of extracranial artery stenosis is more frequent than that of intracranial artery in TIA patients. The coincidence between clinical manifestations and the same type cerebral artery stenosis is more in anterior circulation TIA than that in posterior circulation TIA.
