It has been generally accepted that Asians are more likely to develop intracranial stenosis than extracranial internal carotid artery(ICA) stenosis. However, there has been very few systemic investigation about characteristics of ICA stenosis. We investigated the clinical and angiographical characteristics of ICA stenosis in patients with acute ischemic stroke. From data of Yonsei Stroke Registry, a total 300 acute ischemic stroke patients who were undertaken conventional cerebral angiography from July, 1997 to September, 2000 were investigated. We divided
patients into three groups – isolated intracranial ICA stenosis (IICA group), isolated extracranial ICA stenosis (EICA group), and combined stenosis of intracranial and extracranial ICA stenosis (combined group). A total 107 patients had stenotic lesion in the ICA. Forty five patients were classified to IICA group, 42 patients to EICA group, and 20 patients to combined group. There were no differences among three groups in the degree of stenosis(50.2%, 49.6%, 56.8% each : p= 0.34) and risk factors of ischemic stroke. Frequencies of combined stenosis in anterior and posterior circulation were similar in three groups.ICA stenosis was common in patients with acute ischemic stroke patients. Significant differences of the frequency and risk factors between intracranial and extracranial ICA stenosis were not found. ICA stenosis at the extracranial portion as well as intracranial portion should be considered as a potentially common source of ischemic stroke.ope
