Abstract:
Objective To observe the relationship between cerebral border zone infarction and cerebral artery stenosis or occlusion.Methods 45 patients admitted to our hospital in 2002 were studied retrospectively.They were diagnosied as acute cerebral border zone infarction and classified into anterior border infartion,posterior border infartion and internal border infartion by diffusion weighted MR imaging(DWI). The stenosis or occlusion of cerebral arteries was evaluated by magnetic resonance angiography(MRA) or transcranial doppler(TCD) examinations.Results Cerebral artery stenosis or occlusion was founded in 32 patients(71.1%).The lesions were most located in middle cerebral artery(47.6%),next in internal carotid artery(31%), relatively seldom in anterior cerebral artery and posterior cerebral artery(11.9%). No difference of artery abnormity was found between the patients with single border infarction and the patients with mutiple border infarction.But middle cerebral artery stenosis was more frequently seen in the patients with internal border infartion( P
