Investigation on cerebral collateral circulation situation in patients with cerebral artery stenosis infarction

Objective To explore the cerebral collateral circulation establishment situation in acute infarction patients with intracranial artery stenosis or occlusion.Methods 235 patients with cerebral infarction,whose intracranial arterial stenosis or occlusion were located by imaging,were divided into two groups according to whether the collateral circulation or not,and the promoting factors for establishment of collateral circulation were analyzed by univariate analysis and multinomial logistic regression analysis.Results Univariate analysis showed the highest detection rate of methods for collateral circulation was DSA,and MRA was lower.Logistic regression analysis showed that with collateral circulation as the dependent variable,middle cerebral artery(MCA) stenosis,internal carotid artery(ICA) occlusion and Basilar artery(BA) stenosis were entered into the equation,and OR were 0.598,2.395 and 3.494,with P values were 0.104,0.081,0.015.Conclusion Middle cerebral artery(MCA) stenosis,internal carotid artery(ICA) occlusion and basilar artery(BA) stenosis may stimulate cerebral collateral circulation establishment.
