The Study Of Cerebral Collateral Circulation Establish And The Relationship Between Collateral Circulation And The Recent Prognosis In Patients With Acute Cerebral Infarction

Partâ… :Investigation of cerebral collateral circulation establish in acute cerebral infarction with cerebral artery stenosisObjective To explore the cerebral collateral circulation establishment situation in intracranial artery stenosis or occlusion patients with acute infarction.Methods 235 patients with cerebral infarction ,whose intracranial arterial stenosis or occlusion were to be located by imaging and divided into two groups according to whether the collateral circulation. The constituent ratio of age and gender was matched. Statistical analyses were performed with the SPSS package(version 16.0), and the difference between measurement data were decided by compared t test or single, the difference between the numeration data were assessed by Wilcoxon signed rank sum test, The cerebral collateral circulation establishment situation and its related factors were analyzed with multinomial logistic regression analysis. Results1. Univariate analysis showed: The highest detection rate of collateral circulation was DSA,MRA followed.2. Logistic regression analysis shows that: the formation of cerebral collateral circulation establishment situation in patients with acute infarction is correlated to middle cerebral artery (MCA) stenosis,internal carotid artery (ICA) occlusion and Basilar artery (BA) stenosis . OR were 0.598,2.395,3.494; P values were 0.104,0.081,0.015.Conclusion The stimulative factors of cerebral collateral circulation establishment are middle cerebral artery (MCA) stenosis,internal carotid artery (ICA) occlusion,Basilar artery(BA) stenosis. Partâ…¡:The influence of cerebral collateral circulation situation on the recent prognosis in patients with acute cerebral infarctionObjective To explorer the correlation between the cerebral collateral circulation situation and early prognosis in patients with acute infarction.Methods 166 patients with cerebral infarction were divided into two groups according to whether the collateral circulation is established,All the patients intracranial arterial stenosis or occlusion were to be located by imaging of CTA/MRA and evaluated using MESSS on admission and day 28 after the onset of the illness.and were evaluated using the Barthel index on day 28 and day 90 after the onset of the illness ,and effect prognosis factors were analyzed by univariate analysis and multinomial logistic regression analysis. Results The ability of daily living on day 28 and day 90 after onset of the collateral circulation group were not significantly better than the other group(pï¹¥0.05).Conclusion The recent prognosis of the collateral circulation group were not significantly better than the other group in 166 ICVD patients. It was not appear statistically significant that sample size might be less relevant, it needed further large-scale clinical studies could perorated definite conclusions.
