Analysis of the severity and prognostic factors of cerebral edema after mechanical thrombectomy in patients with anterior circulation occlusion of great vessels / 中风与神经疾病杂志

ABSTRACT

@#Objective　To investigate the severity and prognostic factors of cerebral edema after mechanical thrombectomy in acute ischemic stroke with anterior circulation occlusion of great vessels.Methods　Eighty-three patients with acute cerebral infarction undergone mechanical thrombotomy in our hospital were selected.According to cerebral edema.They were divided into mild group,moderate group and severe group.The patients were divided into the good prognosis group and the poor prognosis group by the improved 90 day Rankin scale.Univariate analysis and Logistic regression analysis were used to analyze the severity of cerebral edema and the prognostic factors.Results　History of hypertension.baseline NHISS>15 points were positively correlated with the severity of cerebral edema.while M2 segment and distal occlusion and successful recanalization were negatively correlated with the severity of cerebral edema.Severe cerebral edema and baseline NHISS>15 were risk factors for poor prognosis 3 months and good collateral circulation and successful recanalization were predictive factors for good prognosis.Conclusion　Baseline NIHSS score>15 points,history of hypertension,non-recanalization of blood vessels and occlusion of cerebral blood vessels were the predictors of the severity of cerebral edema in acute stage after mechanical thrombectomy in patients with anterior circulation occlusion of great vessels.Severity of cerebral edema,baseline NIHSS score,vascular recanalization and collateral circulation status were predictors of neurological recovery after 90 days.
