Lesion pattern and collateral circulation in patients with cerebral infarction caused by severe stenosis or occlusion of unilateral extracranial carotid artery
摘要
Abstract
To investigate the lesion pattern and collateral blood flow in patients with cerebral infarction causedby severe stenosis or occlusion of unilateral extracranial internal carotid artery (ICA).Forty two patients with acute is-chemic stroke shown on diffusion-weighted imaging (DWI) and stenosis ( ^70%) or an occlusion of unilateral extracranial ICA confirmed by cerebral angiography, including 20 patients with severe stenosis and 22 with occlusion, were enrolled in the study within 3 days of onset. The ischemic lesions and primary collateral pathway were compared between two groups, and the relationship between ischemic lesions and primary collateral pathway was analyzed.ResultsMultiple ischemic lesions in severe stenosis or occlusion of extracranial ICA was 80%, the presence of border-zone infarct (BZI) concomitant partial infarct (PI) was higher in severe stenosis group than that in occlusion group( P<0.01). The presence of collateral flow via anterior communicating artery (ACoA) and posterior communicating artery (PCoA) was higher in occlusion group than that in severe stenosis group (P< 0.05), the prevalence of collateral flow via PcoA was higher in severe stenosis group than that in occlusion group( P<0.05). There was an increased prevalence of external border zone infarcts in the group without ACoA collateral flow compared with the group with ACoA collateral flow (P<0.05). No differences were found for any other ischemic lesions and collateral pathway. An acute ischemic lesion in ICA severe stenosis or occlusive disease is mainly multiple. Collateral flow via the ACoA is associated with a reduction of the prevalence external border zone lesions, but not with any other type of ischemic lesion.关键词
