Objective To study the nlanifestation and the clinical significance of the cerebral angiography of the isehemic cerebrovascular diseases.Methods Digital sublraction angiography(DSA)was taken in 312 patients with cerebral infarction and transient ischemic attack(TLA).The distribution of the lesion in the extra/intracranial arteries was compared.Results Cerebral angiography showed that the stenosis and occlusion was dominant in the intracranial arteries at the cerebral infarction in the internal carotid artery system and vertebrobasilar artery system[59.57%(56/94)and 61.90%(26/42)].TIA of internal carotid artery system was mainly because of stenosis of intracranial arteries (68.75%,22/32).TIA of vertebrobasilar artery system was mainly because of stenosis of extracranial arteries(61.70%,29/47).Conclusions The diseases of the intracranial arteries are the main causes of cerebral infarction(including internal carotid artery system and vertebrobasilar artery system) and TIA of internal carotid artery system. The diseases of the extracranial arteries are main causes of TIA of vertebrobasilar artery system.
