Application of Multimodal CT in Assessment and Prognosis of Collateral Circulation in Patients with Acute Anterior Circulation Stroke
Objective:To evaluate the value of multi-mode CT in evaluating collateral circulation and clinical prognosis in patients with acute anterior circulation ischemic stroke.Methods:A total of 50 clinically diagnosed patients with acute procirculatory stroke were enrolled.They were examined by multi-temporal CT angiography(mCTA)and CT perfusion imaging(CTP)before treatment.The CTP parameters of the core infarction area,ischemic penumbral zone and healthy control area were collected,patients were divided into good prognosis group and poor prognosis group according to the modified Rankin score(mRS score).The differences of CTP perfusion parameters between the two groups were compared.The Monen score was used to evaluate the mCTA lateral branches,and the differences of 90-day NHISS score and mRS Score between the good and bad lateral branches were compared.Results:Compared with the poor prognosis group,rCBV was higher in the good prognosis group.At 90 days,we found the good mCTA collateral assessment group had lower NHISS and mRS scores,less neurological impairment,and a better prognosis.Conclusion:Multi-modal CT can better evaluate the collateral circulation of stroke patients,has a certain indication of neurological function deficit and clinical prognosis.
